Problem with ObjectGetValueByTime asap help needed

Demosfen 2019.10.31 09:32

So I use this function to get the value of a trendline for a specific bar:

double trendline(int i)
{
   double trendline=ObjectGetValueByTime(0,"Trendline",iTime(NULL, PERIOD_D1, i),0);
   
   return trendline;
}

then I compare it with bar close using:

if(barclose(1)>trendline(1) && barclose(2)<trendline(2))
{
  entry="buy";
}

with

double barclose(int i)
{   
   MqlRates PriceInformation[];
   ArraySetAsSeries(PriceInformation,true);
   int Data=CopyRates(Symbol(),PERIOD_D1,0,5,PriceInformation);
   double barclose=PriceInformation[i].close;
   
   return barclose;
}

however when I tested this in real life today it produced entry= "buy" when it shouldn't.

Does anyone have an idea why it could happen?

Should I use ChartRedraw(0); ?

Demosfen: xpert is placed is the specific symbol / tf.

Your code breaks if you change to any timeframe not the D1. It's your money.
