CopyClose And CopyOpen return bad result

[hyalavi]

Hello

CopyClose and CopyOpen return bad result after close and reopen metatrader5

I am comparing two copyclose with same parameters and I receive different result from this functions;

My Code:

double iClose1[1],iClose2[1];

CopyClose(_Symbol,PERIOD_MN1,date,1,iClose1);

CopyClose(_Symbol,PERIOD_MN1,date,1,iClose2);

   

if(iClose1[0] != iClose2[0])

Print("ERROR: ",iClose1[0]," != ",iClose2[0]);

else

Print(iClose1[0]," = ",iClose2[0]);

And this code on open metatrader5 print this result:

2454.0 = 2454.0

ERROR: 9.79818532658781e-312 != 7.138640856869782e-189

Can anyone help me?!

Tanks

You have to understand the way double values work, e.g. here!

Two doubles are practically never equal like integers only too close to be different!

if(fabs(iClose1[0]-iClose2[0]) > _Point*0.001) ...
