A simpler way to get Hour() value

MqlDateTime mdt;
TimeCurrent(mdt);

if(Spread<MaxSpread && mdt.hour>=StartHour && mdt.hour<StopHour){

It's working, thank you mate.

if(Spread<MaxSpread&&Hour()>=StartHour&&Hour()<StopHour){

int     Hour(void         ){ return TimeHour(TimeCurrent()); }
int TimeHour(datetime when){ return when/3600 % 24; }
