P.S. it usually happens when the market is not open physically (CFD only) and some candlesticks are very small or inexistent.

At some point somewhere your code is trying to divide by a value of zero. You’ll need to go through the code and look at all the division sums and try to work out which variable or indicator return is causing the zero and then put some code in to ensure a value of zero is never returned. There is no other way really. Something is returning a zero and you just need to narrow down what it is with methodical working through of the code. Maybe sharing the code would make it easier in case someone else on here fancies having a look for you for anything obvious.

You’ve answered your own question there.

Only do division if the divisor variable is superior to 0, it usually avoid this kind of error.

Have you check you variables in the fist candle. Try to define those with the function “once”

Wow … 40 entry conditions … is it successful? Guess you will know now you sorted the divide by zero error? If you want to share the code I’m sure we’d all like to see?
I hadn’t spotted that – 40 conditions! Wow – if I write a strategy with 5 conditions I find it opens one trade a year. How do you satisfy 40 conditions and still get trades to open – even if only half are for entry and half for exit!? I want to see that code now – my interest is piqued!
At the candle close the values for open close and low are fixed and the code is then read. The only way you can have a division by zero is if the close and low are the same value or open and close are the same value.
Multiplying zero by ten still gives you zero so I do not understand why you are doing this.
In your last piece of code you are looking at the candle values for the candle before the one that has just closed – I have no idea why you are doing this either as it could still have a zero value for close – low or open – close.
You could do this to ensure no zero value is calculated:
123bearcandlesize = max((open - close), 0.000000001)bearwicksize = max((close - low), 0.000000001)bearcandlevswick = bearcandlesize / bearwicksizeNote : It is normally preferred that you start a new topic with a new coding problem rather than add on to an old topic.
