The code, if you change f.i barperiod=30, same entries different values:

int timezone = WET;
int profit(){
if(TradeIsOpen and (TradeProfit/TradeUnits/PIP < -50)){exitTrade();}
if(TradeIsOpen and (TradeProfit/TradeUnits/PIP >4)){exitTrade();}
return 0;
}

function tick(){
if(lhour(timezone) == 7 && minute(timezone)==0) { enterShort(profit);}
if(lhour(timezone) == 13 && minute(timezone)==0){ exitShort(); }
// printf("ntick %f",priceClose());
}

function run() {
set(PLOTNOW+PARAMETERS+TICKS);
StartDate = 20180101;
EndDate = 20180301;
BarPeriod = 60;
