      bar_time=Time[0];

3. The EA is attached to EURUSD chart

4. I am trading all the currencies present in market watch using the following code.

   for(int i =0; i< SymbolsTotal(true); i++){

5. I am accessing the previous day low and high using the following code

OrderSend(SymbolName(i,true),OP_SELLSTOP,0.01,(iLow(SymbolName(i,true),PERIOD_H4,1)),1,(iHigh(SymbolName(i,true),PERIOD_H4,1)),0,"",4,0,clrGreen);

EURUSD_high = iHigh( SymbolName(i,true), PERIOD_D1, 1);

try something like this https://docs.mql4.com/series/ihigh

but note: the symbol needs to be shown to get the value, if you are trading multiple currencies be sure to enable the ones you are using

Thank you for the reply.

I am using iHigh and iLow please look at the code in Sl No. 5
I am only accesing the values which are present in Market watch please look at the code in sl no 4.

On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.
