Help with FastMaArray / SlowMaArray

In comparing MA,  if(FastMaArray[0]>SlowMaArray[0] && FastMaArray[1]<(SlowMaArray[1]), please ,what will cause -'0 some expected operator.

It is probably caused by the extra "(" in the code, but it depends on the context of your code (i.e. the rest of the code).

if( FastMaArray[0] > SlowMaArray[0] && FastMaArray[1] < ( SlowMaArray[1] )

You probably meant the following ...

if( FastMaArray[0] > SlowMaArray[0] && FastMaArray[1] < SlowMaArray[1] )

Write self-documenting code

   bool  isUp   = FastMaArray[0] > SlowMaArray[0];
   bool wasUp   = FastMaArray[1] < SlowMaArray[1];
   bool isCross = isUp != wasUp;
if(isCross)
