OpenAlgo
OpenAlgo
Overview
OpenAlgo is a Pine Script v6 helper library for strategies that send their orders to the open-source OpenAlgo order-routing platform through TradingView alerts, typically for Indian markets. It handles the conversions and message formats those strategies repeat: expiry and symbol formats, ATM strikes, the order JSON, custom alert templates, an end-of-day time check and an "all selected filters pass" gate.
This library only builds text and values inside Pine Script. It does not place orders by itself; orders are sent by TradingView alerts that the user configures.

Library "OpenAlgo"
Helpers for strategies that route orders to OpenAlgo through TradingView alerts: symbol and expiry
conversion between OpenAlgo (NFO:NIFTY24FEB2623500CE) and TradingView (NSE:NIFTY260224C23500)
formats, ATM strike rounding, the OpenAlgo order JSON, custom alert templates, an end-of-day time
check and an all-selected-filters gate.
tvExpiry(expiry)

dflt (string): (series string) Returned when there is no prefix. Optional. Default is "NSE".
Returns: (string) The exchange.
rootSymbol(tickerid)
Root symbol of a ticker: the exchange prefix and continuous-contract suffixes ("1!", "2!", "!") removed,

Returns: (string) The root symbol.
atmStrike(price, interval)
Nearest strike to a price on a strike grid (a remainder of exactly half an interval rounds down).

OpenAlgo `placesmartorder` JSON payload.
Parameters:
apikey (string): (series string) OpenAlgo API key.
strategyName (string): (series string) Strategy name.
symbol (string): (series string) OpenAlgo symbol.

Returns: (string) The JSON payload.
fillTemplate(template, signal, symbol, action, exch, price, quantity, strategyName)
Fills a custom alert template. Placeholders: {{signal}}, {{exchange}}, {{symbol}}, {{action}}, {{price}},

pastTime(hhmm)
Whether the bar's time (in the exchange time zone) is at or past an HHMM time, e.g. for an end-of-day
square-off.
Parameters:
hhmm (int): (series int) Time as HHMM, e.g. 1525.
Returns: (bool) `true` from that minute to the end of the day.
allPass(enabled, passed)
Filter gate: `true` when at least one filter is enabled and every enabled filter passed.

This library only builds text and values inside Pine Script. It does not place orders by itself; orders are sent by TradingView alerts that the user configures.
What's inside
- tvExpiry(expiry): converts an OpenAlgo expiry in DDMMMYY form (24FEB26) to TradingView's YYMMDD form (260224).
- exchangeOf(tickerid, dflt) and rootSymbol(tickerid): split a ticker such as NSE:NIFTY1! into its exchange (NSE) and root symbol (NIFTY), removing continuous-contract suffixes.
- atmStrike(price, interval): nearest strike on a strike grid.
- optionSymbol(root, expiry, strike, isCall): OpenAlgo option symbol, for example NIFTY24FEB2623500CE.
- orderJson(...): the OpenAlgo smart-order JSON payload (API key, strategy, symbol, action, exchange, price type, price, product, quantity, position size).
- fillTemplate(...): fills a custom alert template with the placeholders {{signal}}, {{exchange}}, {{symbol}}, {{action}}, {{price}}, {{quantity}} and {{strategy}}.
- pastTime(hhmm): true from a given exchange-time minute (for example 1525) to the end of the day, for end-of-day square-off logic.
- allPass(enabled, passed): true when at least one filter is enabled and every enabled filter passed.
Quick start
Notes
- Never publish a script with a real API key in its defaults. Keep keys in the script's inputs on your own chart, or in the alert message.
- Alert payloads are sent by TradingView only when the user creates an alert with a webhook; the library has no network access of its own.
