Just to be clear, the inside bar lookup is only something available into the backtest (probacktest), not in real live trading. To get this feature, we’ll have to wait more for the multi timeframe support to come later next year.
But still with the inside candel info we will be able to make more accurate/ reliable codes? Because the probacktest modification wikk have all the data that has been accuring inside a candle right?
The tick backtest mode is a way to make sure that trades are triggered in the right order inside a bar, this test were not made correctly before this improvement. So, to answer your question, backtests will be (are) far more accurate than now (previously).
