Can we implement exit after a particular time period (say 30 min) after entry irrespective of the price in api bridge

Hi Suraj!

Yes, it is possible to exit a trade after a particular time period. You can code the same in your strategy logic in a platform of your choice ( Amibroker, Tradingview, MT4).

For example - A logic can be defined to exit after the 'n' number of candles.

A slight variation of the above is followed in Donchian Channel Strategy where if the candle closes below low of the past "n" candles, it sends Long Exit and Short Entry.
