zero divide error but not on all currency pairs

I have a mq4 indicator file that give a zero divide error on any currency pairs with price points that have a zero(0.72735) in front of them.
ie: AUDCAD, NZDUSD,AUDUSD

The trendline alert indicator works fine on any currency pairs with price points when price has no zero(1.32105) in front of the them.

What would be the code to not receive the zero divide error and still give the correct alert on the affected currency pairs when price cross the trendline?


Thanks in advance.

If the prices 0.XXXX return a zero divide, you may have this value in your formulas used as integer (int) instead of double.

changed the int to double but but the zero divide error still occurs.
The indicator works find other wise.
Really need the error to get fixed, then i can work on adding code to place trades.
Could some of the coding experts take a look and correct it?

Could you comment on the changes you made?
The file looks the same to me.
There is no longer a zero error in tester, however the alerts no longer work even on the charts that have no zero(1.70446) in front of the them.

Look the below and compare to what it was in your initial code. That's the only thing I modified. Nothing else.

Inserted Code
double pendiente /*= (price2 - price1) / lapse*/;
if(lapse != 0) pendiente = (price2 - price1) / lapse;

Thanks for the modifications.
I will test it out on a live chart tonight instead of the tester.
The tester might be acting up.
