whats wrong with this code?

if(max_spread_filter && (Ask-Bid)/myPoint>max_spread) enableopen=false;


gives a critical error when trying to backtest?

Possible errors :
1. Type of 'max_spread_filter' not 'bool'
2. 'myPoint' == 0.0

Divide by zero is the only critical error that can give. Basically myPoint is 0.

very difficult to say without seeing how u declared the variables like max_spread_filter.. at first glance altho its not required always you should bracket the execution portion after your if statement runs. If youd like me to help I'd have to see more of the code. One more thing, it doesnt look like MyPoint has any value. Again, very difficult to say just from one snippet of code bc we need to see the declarations and how the code flows.

extern bool max_spread_filter=true;
extern double max_spread=5.0;

double myPoint, mySpread, myStopLevel,myTickValue,myTickSize,myLotValue;
int myDigits;

init:


SetPoint();

start:


 bool enableopen = true;
   if(max_spread_filter && (Ask-Bid)/myPoint<max_spread) enableopen=false;
 if(enableopen)



function:


void SetPoint()
{

   myPoint = MarketInfo(Symbol(),MODE_POINT);
   mySpread = MarketInfo(Symbol(),MODE_SPREAD);
   myDigits = MarketInfo(Symbol(),MODE_DIGITS);
   myStopLevel = MarketInfo(Symbol(),MODE_STOPLEVEL);
   myTickValue = MarketInfo(Symbol(),MODE_TICKVALUE);
   myTickSize = MarketInfo(Symbol(),MODE_TICKSIZE);
   myLotValue = myTickValue/myTickSize;

   if(
         myDigits==3 ||
         myDigits==5
     )
      {
         myPoint = myPoint * 10;
         mySpread = mySpread / 10;
         myStopLevel = myStopLevel / 10;
         myDigits = myDigits -1;
      }

}
