Thank you so much @jstap I have read your link and many other related links. Including checking the code. But the result is the same error. Is it possible that the error occurred not from the code, but from some settings? And how can I fix it?
So it says

can't open "S:\www-node\Server\apps\fxdreema\components\builder\templates\export\MQL5\compiler\MQL5\Include\WinAPI\winapi.mqh" include file
'AlgoTradingStatus' - undeclared identifier

For your link I make it on MT4 and Complete run and working perfectly.
But MT5 with MT5 code is not work with error >> can't open "S:\www-node\Server .... winapi.mqh

I do not know, I only used it with MT4
