What's New in 2.0.5

Bug-fix release: NaN handling in the indicator kernels. Chaining one indicator into another was silently producing nothing, because every indicator emits warm-up NaNs and the moving-average kernels let a single NaN poison their running accumulator for the rest of the series (#2029).

df["RSI_wma"] = ta.rsi(ta.wma(df["close"], 55), 14)
df["RSI_avg"] = ta.wma(df["RSI_wma"], 9)      # was: NaN on every row
ta.crossover(df["RSI_wma"], df["RSI_avg"]).sum()   # was: 0 across 1600 bars

Three of these failed silently with plausible numbers rather than NaN:

stdev returned 0.0, not NaN, for the rest of the series after a NaN (f64::max yields the other operand against NaN), collapsing Bollinger width.
rsi returned a flat 100 over an upstream indicator's warm-up: a NaN delta is neither a gain nor a loss, so avg_loss seeded to 0 and took the "no losses" branch.
median panicked through the PyO3 boundary on any window containing a NaN.

ta.crossover / ta.crossunder were never at fault and are unchanged.

The NaN contract is now stated and enforced on both backends. Rolling-window kernels are window-local: a NaN blanks only the windows containing it and the series recovers once it slides out, the same rule as pandas .rolling(period). Recursive kernels (the EMA family) skip leading NaNs and seed at the first finite value. The Rust core and the pure-NumPy fallback had drifted apart here, so the same script gave different answers from a wheel and from a source checkout; they are now checked against each other in CI.

ta.vi and ta.ulcerindex returned all-NaN on clean OHLCV and now produce values. For NaN-free input every other indicator is unchanged, bit for bit.

What's New in 2.0.4

GTT (Good Till Triggered) orders: placegttorder, modifygttorder, cancelgttorder and gttorderbook, covering both SINGLE and OCO triggers. An impossible trigger spec is refused locally before anything is sent.
Strategy module API: nine methods on the API-key surface - strategylist, strategystatus, strategystart, strategystop, strategycloseall, strategycloseleg, strategyruns, strategyorders and strategyevents.
Strategy webhook client revamped for the new protocol: start(mode) and stop() for batch strategies, long_entry / long_exit / short_entry / short_exit for signal strategies. mode on start has no default, the token is never rendered in a repr, and every documented rejection is returned with its result label instead of raised.
Breaking: Strategy.strategyorder() was removed. The webhook it posted to no longer exists. See Strategy Module for the replacements.

What's New in 2.0.0

Version 2.0.0 replaces the old Numba/JIT indicator engine with a Rust core (via PyO3):

No optional extra, no Numba. Indicators are compiled into the wheel. The legacy pip install openalgo[indicators] extra and the numba/llvmlite dependencies are removed; pip install openalgo is all you need.
Python 3.12, 3.13 and 3.14 are all supported (abi3 wheels). Numba previously blocked newer Python/NumPy versions.
New TA-Lib-compatible indicators: mom, rocp, rocr, rocr100, apo, midpoint, midprice, avgprice, medprice, typprice, wclprice, plus_dm, minus_dm, dx, adxr, stochf, linregangle, linregintercept.
Performance: every indicator is O(n). Benchmarked head-to-head with TA-Lib on 924k bars, the regression/statistics family (linreg, tsf, stddev, cci, macd, ...) runs faster than TA-Lib; the rest are on par. See the performance comparison and TA-Lib compatibility notes.
Backward compatible: the from openalgo import ta API is unchanged - existing code keeps working without modification.

Installation

To install the OpenAlgo Python library, use pip:

pip install openalgo

The 100+ technical indicators are built in (powered by a Rust core); no extra install step or optional dependency is required.

Get the OpenAlgo apikey

Make sure that your OpenAlgo Application is running. Login to OpenAlgo Application with valid credentials and get the OpenAlgo apikey.

For detailed function parameters refer to the API Documentation.

Getting Started with OpenAlgo

First, import the api class from the OpenAlgo library and initialize it with your API key:

from openalgo import api

# Replace 'your_api_key_here' with your actual API key
# Specify the host URL with your hosted domain or ngrok domain.
# If running locally in windows then use the default host value.
client = api(api_key='your_api_key_here', host='http://127.0.0.1:5000')

Check OpenAlgo Version

import openalgo
openalgo.__version__

Technical Indicators (100+)

OpenAlgo ships 100+ technical indicators powered by a Rust core (via PyO3) — including trend, momentum, volatility, volume, oscillators, statistics, and hybrid indicators. They are built in; no optional dependency or extra install step:

pip install openalgo

Quick example:

import numpy as np
from openalgo import ta

close = np.array([100, 101, 102, 103, 104, 105, 106, 107, 108, 109], dtype=float)
high  = close + 0.5
low   = close - 0.5

# Trend
sma   = ta.sma(close, period=5)
ema   = ta.ema(close, period=5)
supertrend, direction = ta.supertrend(high, low, close, period=7, multiplier=3.0)

# Momentum
rsi   = ta.rsi(close, period=14)
macd_line, signal_line, hist = ta.macd(close, fast=12, slow=26, signal=9)

# Volatility
atr   = ta.atr(high, low, close, period=14)
upper, middle, lower = ta.bbands(close, period=20, std=2.0)

Many indicators are value-compatible with TA-Lib; where OpenAlgo intentionally follows TradingView/Pine conventions instead (EMA/ATR/ADX seeding, etc.), the differences are documented in the TA-Lib compatibility notes.

WebSocket Verbose Control

The streaming feed supports verbosity levels (0 silent, 1 connection/auth/subscription info, 2 full debug with every tick):

client = api(
    api_key="your_api_key",
    host="http://127.0.0.1:5000",
    ws_url="ws://127.0.0.1:8765",
    verbose=1,                 # 0 / 1 / True / 2
)

PlaceGTTOrder Example

A GTT (Good Till Triggered) order is a price trigger that sits with the broker until LTP crosses your level, then places the underlying order automatically.

There are two shapes, and picking the wrong one is the usual mistake:

Type	Use when	Triggers	Orders fired
`SINGLE`	One entry or exit at a level	1	1
`OCO`	You hold a position and want both a stoploss and a target, whichever hits first	2	1 of 2, the other is auto-cancelled

For a SINGLE, exactly one of triggerprice_sl / triggerprice_tg carries your level and the other stays 0. Pick by where the trigger sits relative to LTP: triggerprice_sl for a level below LTP (sell stop-loss, buy the dip), triggerprice_tg for one above (breakout buy, sell at target). A SINGLE has no stoploss leg, so the suffix is only a directional hint.

For an OCO, the suffix is a real role and all four fields are required: triggerprice_sl with its stoploss limit, and triggerprice_tg with its target limit, where triggerprice_sl < triggerprice_tg.

GTT accepts CNC and NRML only. MIS is refused: a GTT can sit for days and MIS is squared off the same session.

# SINGLE - "Buy IDEA if it dips to 9.55, with a LIMIT order at 9.50"
# LTP is above 9.55, so the trigger sits below it -> triggerprice_sl
response = client.placegttorder(
    strategy="My GTT Strategy",
    symbol="IDEA",
    action="BUY",
    exchange="NSE",
    product="CNC",
    quantity=1,
    price_type="LIMIT",
    price=9.50,
    triggerprice_sl=9.55
)
print(response)

# SINGLE - "Buy RELIANCE at MARKET if it breaks above 1450"
# LTP is below 1450, so the trigger sits above it -> triggerprice_tg
response = client.placegttorder(
    strategy="My GTT Strategy",
    symbol="RELIANCE",
    action="BUY",
    exchange="NSE",
    product="CNC",
    quantity=1,
    price_type="MARKET",
    price=0,
    triggerprice_tg=1450
)

# OCO - "I am short 5 INFY. Stop me out at 1480, take profit at 1620"
# price is 0: OCO prices each leg separately through stoploss and target
response = client.placegttorder(
    strategy="Bracket OCO",
    trigger_type="OCO",
    symbol="INFY",
    action="SELL",
    exchange="NSE",
    product="CNC",
    quantity=5,
    price_type="LIMIT",
    price=0,
    triggerprice_sl=1480,
    stoploss=1478,
    triggerprice_tg=1620,
    target=1622
)

PlaceGTTOrder Response:

{"status": "success", "trigger_id": "23132604291205"}

Save the trigger_id: modify and cancel both need it.

ModifyGTTOrder Example

Modify is a full replacement, not a patch. Every field on the trigger is replaced by what the call sends, so pass everything you want to keep rather than only the values that changed.

response = client.modifygttorder(
    trigger_id="23132604291205",
    strategy="My GTT Strategy",
    symbol="IDEA",
    action="BUY",
    exchange="NSE",
    product="CNC",
    quantity=1,
    price_type="LIMIT",
    price=9.60,           # was 9.50
    triggerprice_sl=9.65  # was 9.55
)
print(response)

ModifyGTTOrder Response:

{"status": "success", "trigger_id": "23132604291205"}

Trigger prices, limit prices, quantity and pricetype are modifiable. trigger_type, symbol, exchange and action are not - cancel and re-place instead. Only active GTTs can be modified; triggered, cancelled and expired ones are immutable.

CancelGTTOrder Example

response = client.cancelgttorder(
    trigger_id="23132604291205",
    strategy="My GTT Strategy"
)
print(response)

CancelGTTOrder Response:

{"status": "success", "trigger_id": "23132604291205"}

Cancelling an OCO removes both legs atomically; there is no per-leg cancel.

GTTOrderBook Example

By default this lists active triggers only, the ones that can still fire. Pass status="all" to include the history as well (triggered, cancelled, expired, rejected), ordered active first; in analyzer mode a fired leg also carries the triggered_order_id of the sandbox order it placed.

# Active triggers only (default)
response = client.gttorderbook()
print(response)

# Active triggers first, then the triggered / cancelled / expired history
response = client.gttorderbook(status="all")
for gtt in response["data"]:
    print(gtt["trigger_id"], gtt["status"], gtt["symbol"], gtt["trigger_prices"])

trigger_prices is sorted ascending: a SINGLE has one element and one leg, an OCO has two of each with the stoploss first.

The SDK refuses an impossible trigger spec before anything leaves the machine, and returns the refusal in the same shape as an API error:

# SINGLE with no trigger price at all
client.placegttorder(symbol="IDEA", action="BUY", exchange="NSE",
                     product="CNC", quantity=1, price=9.50)
# {'status': 'error',
#  'message': 'SINGLE GTT requires a positive triggerprice_sl or triggerprice_tg.',
#  'error_type': 'validation_error'}

Strategy Module

OpenAlgo's /strategy module runs multi-leg options strategies with end-to-end risk management, plus a signal-driven mode for TradingView alerts. Two surfaces reach it, and they take different credentials:

Surface	Credential	Use for
`api(api_key=...)`	Your OpenAlgo API key	Lifecycle and reads: list, status, start, stop, close_all, close_leg, runs, orders, events
`Strategy(...)`	The strategy's `oaws_` webhook token	The public webhook at `/strategy/webhook/<token>`, which is what TradingView posts to

Building a strategy stays in the browser wizard at /strategy. The API-key surface is lifecycle plus reads only: nothing on it can create a strategy, edit its configuration, enable live trading, rotate a webhook token, or delete anything.

Two strategy kinds, and each refuses the other's vocabulary:

batch - a multi-leg spread entered and exited as a unit. start / stop.
signal - one alert moves one leg. long_entry / long_exit / short_entry / short_exit. There is no start and no mode: the first signal after the platform session boundary opens the run.

Four rules worth knowing before you call anything:

mode on start is required and is never defaulted, in the SDK or on the server. It is a keyword argument with no default, so omitting it is a TypeError rather than a live order.
Live is opt-in per strategy. A strategy is created sandbox-only, and mode="live" is refused with a 409 until the operator enables live trading on the strategy page.
An accepted stop is not proof of flatness. Read stop_pending and the per-leg outcomes; never infer flatness from the HTTP status.
A strategy that is not yours answers 404, identical to one that does not exist, so the id space cannot be probed.

StrategyList Example

response = client.strategylist()
print(response)

# Optional filters. An out-of-vocabulary status is a 400, not an empty list.
client.strategylist(status="running")
client.strategylist(q="NIFTY")

StrategyList Response:

{
  "status": "success",
  "data": [
    {
      "id": 7,
      "name": "NIFTY Short Straddle",
      "strategy_kind": "batch",
      "direction": "both",
      "underlying": "NIFTY",
      "underlying_exchange": "NSE_INDEX",
      "strategy_type": "intraday",
      "entry_time": "09:20",
      "exit_time": "15:10",
      "product": "NRML",
      "pricetype": "MARKET",
      "overall_sl_mtm": -5000.0,
      "overall_target_mtm": 8000.0,
      "live_enabled": false,
      "status": "running",
      "current_run_id": 42,
      "last_finalized_run": {"id": 41, "pnl_realized": 1250.0, "stopped_at": "2026-08-29T09:40:11.482913+00:00"}
    }
  ]
}

The list form omits legs; call strategystatus for one strategy's legs. For a stopped strategy, last_finalized_run.pnl_realized is the durable final P&L.

StrategyStatus Example

response = client.strategystatus(strategy_id=7)
print(response)

StrategyStatus Response:

{
  "status": "success",
  "data": {
    "id": 7,
    "name": "NIFTY Short Straddle",
    "status": "running",
    "current_run_id": 42,
    "legs": [
      {"id": 1, "segment": "options", "position": "S", "lots": 1, "option_type": "CE",
       "strike_mode": "atm", "atm_offset": "ATM", "expiry": "weekly",
       "sl_pts": 30, "target_pts": 60, "trail": {"x": 10, "y": 5}}
    ]
  },
  "run": {
    "id": 42,
    "mode": "sandbox",
    "broker": "sandbox",
    "started_at": "2026-08-30T03:50:11.402118+00:00",
    "stopped_at": null,
    "stop_reason": null,
    "stop_requested_at": null,
    "stop_requested_reason": null,
    "pnl_realized": 0.0,
    "pnl_peak": 0.0,
    "pnl_trough": 0.0,
    "trigger_source": "manual",
    "resolved_expiries": {"1": "04-SEP-26", "2": "04-SEP-26"}
  }
}

run is null whenever the strategy has no current run, which is the normal state of a stopped strategy. Prefer it over the strategy's own status when you need to know whether anything is actually open. A populated stop_requested_reason means a stop is durable but not yet confirmed flat: the run is still current and still managed.

StrategyStart Example

Starts a batch strategy: every leg's entry order is placed.

response = client.strategystart(strategy_id=7, mode="sandbox")
print(response)

# Partial success is a 200. Check each leg rather than assuming they all
# reached the market.
for leg in response.get("legs", []):
    if not leg["ok"]:
        print(f"leg {leg['leg_id']} rejected: {leg['error']}")

StrategyStart Response:

{
  "status": "success",
  "run_id": 42,
  "mode": "sandbox",
  "legs": [
    {"leg_id": 1, "ok": true, "acknowledged": true,
     "symbol": "NIFTY04SEP2624500CE", "broker_order_id": "26083004118201", "error": null},
    {"leg_id": 2, "ok": true, "acknowledged": true,
     "symbol": "NIFTY04SEP2624500PE", "broker_order_id": "26083004118244", "error": null}
  ]
}

ok: true with acknowledged: false is a real broker order whose id could not be written back, not a rejection - it reconciles itself. A second start against a running strategy answers 409, so two triggers firing at once cannot both place a full set of entries.

StrategyStop Example

Exits every owned position at market.

response = client.strategystop(strategy_id=7)
print(response)

StrategyStop Response:

{
  "status": "success",
  "run_id": 42,
  "stop_pending": true,
  "exits": [
    {"leg_id": 1, "ok": true, "position_ref": "969bc536b1c14d15992f730c2c136d7a",
     "exit_owner": "live", "error": null}
  ]
}

stop_pending: true means the request is durable and its exits were accepted, but the run stays open, subscribed and managed until fills prove every position is flat. A 409 can also carry stop_pending: true when an unfilled entry or a refused exit still needs management - retry the stop in that case.

StrategyCloseAll Example

Same stop mechanics as strategystop, different audit intent: a close_all_manual event is written first, which proves an operator asked for a flatten.

response = client.strategycloseall(strategy_id=7)
print(response)

StrategyCloseLeg Example

Exits one leg at market; the run continues with the rest. leg_id is the id the wizard assigned within the strategy, the same value that appears in legs[].id on strategystatus. It is not an order id.

response = client.strategycloseleg(strategy_id=7, leg_id=2)
print(response)

StrategyCloseLeg Response:

{
  "status": "success",
  "run_id": 42,
  "leg_id": 2,
  "run_stopped": false,
  "exits": [
    {"leg_id": 2, "ok": true, "position_ref": "80bb5fc9333f4922a582229f06a0fe45",
     "exit_owner": "live", "error": null}
  ]
}

run_stopped reports only what this call could prove. A live broker normally acknowledges before its fill, so even the last accepted exit returns false and the fill finalises the run later. A leg_id that names no open leg is a 409, not a 404.

StrategyRuns Example

Every activation of a strategy, newest first.

response = client.strategyruns(strategy_id=7, limit=10)
print(response)

StrategyRuns Response:

{
  "status": "success",
  "data": [
    {
      "id": 42,
      "strategy_id": 7,
      "mode": "sandbox",
      "broker": "sandbox",
      "started_at": "2026-08-30T03:50:11.402118+00:00",
      "stopped_at": "2026-08-30T09:40:02.771905+00:00",
      "stop_reason": "eod",
      "pnl_realized": 3140.5,
      "pnl_peak": 4880.0,
      "pnl_trough": -1220.25,
      "trigger_source": "manual",
      "resolved_expiries": {"1": "04-SEP-26", "2": "04-SEP-26"}
    }
  ]
}

limit is 1 to 500 and is bounded rather than clamped: a value outside the range is a 400, so you learn it was refused. An overall threshold triggers an exit, it does not promise the result - market exits fill at the available bid/ask, so pnl_realized can differ from the threshold that caused the stop.

StrategyOrders Example

Every order the engine placed, oldest first, so an entry always precedes its exit.

response = client.strategyorders(strategy_id=7)

# Narrow a long history to one run. A run belonging to another strategy matches
# nothing rather than leaking its orders.
response = client.strategyorders(strategy_id=7, run_id=42)
print(response)

StrategyOrders Response:

{
  "status": "success",
  "data": [
    {
      "id": 318,
      "run_id": 42,
      "leg_id": 1,
      "kind": "entry",
      "position_ref": "969bc536b1c14d15992f730c2c136d7a",
      "broker_order_id": "26083004118201",
      "symbol": "NIFTY04SEP2624500CE",
      "exchange": "NFO",
      "action": "SELL",
      "qty": 75,
      "product": "NRML",
      "pricetype": "MARKET",
      "price": 0.0,
      "status": "complete",
      "placed_at": "2026-08-30T03:50:11.610224+00:00",
      "filled_at": "2026-08-30T03:50:12.004881+00:00",
      "avg_fill_price": 142.35,
      "filled_qty": 75,
      "reject_reason": null
    }
  ]
}

A row is written before the broker answers, so an order can appear with status: "pending" and a null broker_order_id. That is deliberate: an order that reached the broker but was never recorded would be invisible to crash recovery.

StrategyEvents Example

The risk-event audit trail, newest first. The trail is append-only.

response = client.strategyevents(strategy_id=7, limit=100)

# Filters. An out-of-vocabulary kind or severity is a 400, not an empty list.
client.strategyevents(strategy_id=7, run_id=42)
client.strategyevents(strategy_id=7, severity="critical")
client.strategyevents(strategy_id=7, kind="run_stop_failed")

StrategyEvents Response:

{
  "status": "success",
  "data": [
    {
      "id": 2041,
      "run_id": 42,
      "strategy_id": 7,
      "ts": "2026-08-30T06:21:40.104112+00:00",
      "kind": "leg_sl_hit",
      "severity": "warn",
      "leg_id": 1,
      "message": "stop loss hit: last price 172.8 is at or above the stop 172.35 on a short position",
      "payload": null
    }
  ]
}

Events an operator should not ignore:

Kind	Severity	Meaning
`run_stop_requested`	info	The stop is durable and new signal entries are gated. Not proof the broker is flat
`run_stop_failed`	critical	The broker refused a stop's exits and the run is still holding those positions
`order_ack_unrecorded`	critical	The broker accepted an order but its acknowledgement could not be written; it reconciles itself
`leg_expiry_fallback`	warn	The chain did not list the expiry rank the leg asked for, so a nearer one was used
`flip_outgoing_exit_rejected`	critical	The outgoing side of a signal flip is still held

Strategy Webhook Example

The public webhook is what TradingView and other alert senders post to. It is not under /api/v1 and takes no API key: the oaws_ token in the URL is the whole credential. It is shown exactly once, in the browser, when the strategy is created or its token is rotated - no endpoint returns it. Treat it as a password.

from openalgo import Strategy

strategy = Strategy(
    host_url="http://127.0.0.1:5000",
    webhook_token="oaws_your_webhook_token_here"
)

# Batch strategy: mode is required on start and never defaulted
print(strategy.start("sandbox"))
print(strategy.stop())

Webhook Start Response:

{
  "status": "success",
  "result": "ok",
  "message": "Strategy start accepted",
  "strategy_id": 7,
  "run_id": 42
}

# Signal strategy: one alert moves one leg. Name the leg by id, or by symbol
# and exchange. leg_id wins when both are given.
strategy.long_entry(leg_id=1)
strategy.long_exit(leg_id=1)
strategy.short_entry(symbol="RELIANCE", exchange="NSE")
strategy.short_exit(symbol="RELIANCE", exchange="NSE")

Every documented outcome is returned, not raised, because the result label is the contract:

response = strategy.start("sandbox")
result = response.get("result")

if result == "ok":
    print(f"accepted, run {response['run_id']}")
elif result == "rejected_dedupe":
    print("duplicate delivery within 60s, already handled")   # HTTP 200
elif result == "rejected_cooling_off":
    print("stopped within the last 30s, try again shortly")   # HTTP 409
elif result == "rejected_live_disabled":
    print("enable live trading on the strategy page first")   # HTTP 403

A signal that does nothing is a success with a note, not a failure: Signal accepted (already_long). The notes are already_long, already_short, no_matching_position, outside_entry_window and outside_trading_window. Reporting a no-op as a failure invites a retry, and a retry on an order path is how one alert becomes two positions. Being refused is different: a signal blocked by the strategy's direction, or naming a leg that does not exist, answers rejected_invalid_action with the engine's own message.
