MQ4 code to get signal from two indicators on same window with different scale.

[Dinh Tuan Tran]

Hello,

I combined two indicators such as momentum and moving average of oscillator (OsMA) on same window. I add level 100 on momentum parameter and level 0 on OsMA parameter. Now I would like to use these two parameters to determine the signal by coding on MQ4. Anyone can help? The point here I can spot on chart visually but I do not know how to apply in MQ4

For example I want to spot when the level 100 of momentum is above Level 0 of OsMA.

Appreciate if anyone can help me

Thanks

   Momentum is a price difference (±0.01234). OsMA is an oscillator (0 … 100).

   If the window scale is 0 … 100, your momentum is a straight line at the bottom, useless.

   If the window scale is ±0.01234, your oscillator is mostly off screen, useless.

   Read them in, check for a cross. What's the problem?

   double aPrev = …(i+1), aCurr = …(i),
          bPrev = …(i+1), bCurr = …(i);
   bool   wasUp = aPrev > bPrev,
           isUp = aCurr > bCurr,
        isCross = isUp != wasUp;
