When dealing with time, a lot of people use strings; they can not be optimized. Using (int) seconds or (double) hours and fraction can be inputs.

Invalid time, format is HH:MMinput string StartTradingTime ="00.11"; input string StopTradingTime ="23.10"; bool CheckTradingTime() { if (StringSubstr (CurrentTime,0,5) >=StartTradingTime) TradingIsAllowed=true; if (StringSubstr (CurrentTime,0,5) >=StopTradingTime) TradingIsAllowed=false; return TradingIsAllowed; }
Optimizable. input int StartTradingTime = 11*60; // "00:11:00" input int StopTradingTime = 23*3600+10*60; // "23:10:00"; bool CheckTradingTime(){ int now = time(); return StartTradingTime <= now && now < StopTradingTime; }
