division by 0 error

RateOfChangeA = ROC[3](close) RateOfChangeB = ROC[3](close[3]) Change = RateOfChangeA/RateOfChangeB RETURN change hi guys, I have read through the forums & found that this issue exists in several scenarios, i understand that the divisor cannot divide by 0 but neither of these should be throwing a 0. does anyone know what would cause this error with the code above, the code worked well without these lines but now that i have added them it stops the strategy from working. thanks in advance & apologies if this has been answered. the threads i read never actually had a fix just several ideas that seemed impractical.

```
RateOfChangeA = ROC[3](close)
RateOfChangeB = ROC[3](close[3])
Change = RateOfChangeA/RateOfChangeB

RETURN change
```
hi guys,

I have read through the forums & found that this issue exists in several scenarios, i understand that the divisor cannot divide by 0 but neither of these should be throwing a 0.

does anyone know what would cause this error with the code above, the code worked well without these lines but now that i have added them it stops the strategy from working.

thanks in advance & apologies if this has been answered. the threads i read never actually had a fix just several ideas that seemed impractical.

i think i found the issue. its in the RateOfChangeB ROC[3](close[3]) i changed to RateOfChangeB ROC[3](close[2]). lets see if this throws the error

Why do you think that this is this code that is throwing this error please? Are you using a CALL to get the value of “change”?

Hi Nicolas, the strategy was working fine & running without the addition of the ROC function. This is what makes me think it’s this piece of code.

I am still quite new to coding & strategy development so I am unsure exactly what a call is. I am assuming that a call is used when I want to use the parameter “change”.

“Change” is used further in the code when sending buy or sell signal.

apologies for code below doing this on mobile & having issues with editor.

IF Change >= 9 THEN

BUY X at market

ENDIF

Side note changing the variable didn’t help

Try to replace your code with:
```
RateOfChangeA = ROC[3](close)
RateOfChangeB = ROC[3](close[3])
Change = RateOfChangeA/max(ticksize,RateOfChangeB)

RETURN change
```
It will ensure that the divisor is at least minimal size of a tick.
