| Default values | Available values
| -------------- | ----------------
| bidask = 1 | 0, 1 // 1 = bidask active, 0 = bidask inactive
| heartbeat = 1 | 0, 1 // 1 = print heartbeat message, 0 = don't print heartbeat message
| replay = 0 | 0, 1 // 1 = Feed replay, 0 = Normal feed ( default - If parameter not entered then replay = 0 )
isSocketConnected() // Check if socket is connected or not. Returns Boolean value
getMarketStatus() // Return the current market status
rtSubscribe( newSymbols ) // Dynamically subscribe to new symbols // newSymbols is array of symbol
rtUnsubscribe( oldSymbols ) // Dynamically unsubscribe from currently subscribed symbols // oldSymbols is array of symbol
rtDisconnect() // Disconnect live data feed and close socket connection
The library will check for internet connection and once steady will try to re-connect the Websocket.
historical.auth(user, pwd); // For authentication.
from = formatTime(2021, 3, 2, 9, 15) // (year, month, date, hour, minute) // hour in 24 hour format
to = formatTime(2021, 3, 5, 9, 15) // (year, month, date, hour, minute) // hour in 24 hour format
All API calls returns a promise. You can use .then(...)
and .catch(...)
OR async
and await
method
You can use “duration” instead of using “from and to” in both the above functions. If you are using “duration” then, the function will be like:
| Default values | Available values

| response = 'json' | response : 'json', 'csv'
| bidask = 1 | bidask: 1, 0 // 1 – bidask feed active , 0 – bidask feed inactive
| interval = '1min' | interval:'1min', '2min', '3min', '5min', '10min', '15min', '30min', '60min', 'EOD'
| nticks = 2000 | nticks: Any number // Max upto last 5 days of ticks
| nbars = 200 | nbars: Any number
| getSymbolId = 0 | getSymbolId : 1, 0 // 1 - symbolId active , 0 - symbolId inactive
| segment = 'FO' | segment: 'FO', 'EQ', 'MCX', 'BSEFO', 'BSEEQ'
| topsegment = 'NSEFUT' | topsegment: 'NSEFUT', 'NSEEQ', 'NSEOPT', 'CDS', 'MCX'
| top = 50 | top: Any number
*symbol in historical api is symbol name. For eg: 'NIFTY-I' or 'RELIANCE' etc.
*In historical.getBhavCopy, current date is default. Date format is 'yyyy-mm-dd'
