Calculating the number of bars between Bar[0] backwards to a given starting point.

[Stanfillirenfro]

Hello !
Here is the problem.

I want to have the number of bars between a fixed starting point to the current bar, the Bar[0]. For the starting point, I have chosen the moment when the faster moving average crosses above the slower one. At this moment, I save the index of the bar in int startP. On the output window, I have 3758, 3759…. Minutes later, couple of bars are printed on the chart from the starting point stardP. I want to know the number of bars between these two points (Bar[0] and startP). I make the following calculation. int barsDiff = CurrentBar - startP. On the output window, I have the value 0. It can not be zero, because I can count manually the bars and I have at least 10 bars.


Here is the piece of my code:

  if(myFasterMA CrossesAbove mySlowerMA)
  {
     if(!flagUp)
     {
        int startP    = CurrentBar;
        falgUp = true;
     }

     int barsDiff = CurrentBar-startP;
  }

Could someone please points out wher I am mistaking?

Thanks in advance!

Hello Stanfillirenfro,

It appears you are only barsDiff to the CurrentBar minus startP when the CrossAbove occurs, so that would be 0 bars ago.

Perhaps you are wanting to calculate this on every bar, not just in the logic block when the CrossAbove occurs?

Many thanks NinjaTrader_ChelseaB for your reply.

Here is the idea.

1) I want the CrossAbove to occur.
2) After the CossAbove is in place, I want to count each subsequent bar formed.

Is the calculation at the wrong place inn the code?

Thanks in advance!

Hello Stanfillirenfro,

" After the CossAbove is in place, I want to count each subsequent bar formed."

Your code to calculate the number of bars is within the scope of CrossAbove condition so it will only evaluate when there is a CrossAbove.

Calculate outside of the scope of the logic block so this evaluates on every bar.

See the section on Scope in the Basic Syntax support article linked below.
