In Amibroker the general way of computing the Equity curve is to backtest the given trading system and the report computes the equity curve, drawdown…etc results for you. And to compute the equity curve you have to push the backtest button every time which makes you little uncomfortable if you want to measure the Equity curve in realtime.
This internet has very less resource on how to backtest a strategy on intraday basis as most of the strategy adapted so far in marketcalls are carry forward strategy. Strategies like Ichimoku Cloud TSL, SDA2 Trend Trading System and Supertrend etc are mostly carry forward strategy. And to implement a pratical intraday strategy you need to mix mathematical models with time based strategies (i.e) when to initiate a position ,when to exit and whent to stop the trade during the day.
