Error : zero divide : Why ?

New comment

Hello

I have a pb that i can't solve :

double ab =iMA("EURUSD",0,1,0,MODE_SMA,PRICE_CLOSE,pos);
double bc =iMA("USDCHF",0,1,0,MODE_SMA,PRICE_CLOSE,pos);
      
double ca = 1/(ab*bc);

ab is correct (i can see it in a buffer), bc is correct too but 1/(ab*ac) return an error !

Can you explain me wghy ?

How do you know that bc is correct?

Where is pos assigned a value?

Is this on a live chart or the tester?

I think ab of bc is zero sometimes but not all the time.


might be a reason why

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.

Thank you, there must be an error while reading a candle.
The pos value is the number of the candle in the loop that reads the candles ...

you need to check for missing candle history, see post #3

You are assuming that both symbols have the same index and bar count.
