Using iVolume to determine a new day would be very unreliable. Instead simply use iTime . Try the following: datetime currentDay; void OnTick() { if(currentDay!=iTime(NULL, PERIOD_D1,0)) { int buyTicket=OrderSend(Symbol(),OP_BUYSTOP,0.01,P,3,S1,R1,"MyBuyPosition",7777,0,clrGreen); currentDay=iTime(NULL, PERIOD_D1, 0); } }
