Hello, can I ask a question here? It has been confused me for a long time. Thank you! When doing back test in Visual mode, instead of automatically proceeding, we can manually show the bar one by one by pressing F12 key. What I want to do is that by pressing one key, for example S key (the key code is 0x53), then F12 will be sent to MT4 five times. The code is as below. The result is, when in back test, pressing S key will show bars just as F12 was entered, however, only one, or two, at most three bars come out every time! I wonder why it does not...

Thanks for your quick reply! >What does F12 do on the MT4? When doing back test manually, F12 moves the chart forward by 1 candlestick at a time. The url below describes this. https://www.fxdayjob.com/manual-backtesting-in-mt4 >With the code above when you click S it will call click A and print A 5x However, this does not apply to F12. As I wrote yesterday, pressing S key will show only one , or two bars, at most three bars come out at a time, not 5x! Maybe this is the bug of MT4 back test?? {image}

I tried your code and found on back test "A" was printed for five times. So I guess Backtest window does receive F12 5x but can not deal with for some reason. I will new a thread to ask other guys if there is workaround. Thank you so much for your time and advice!
