Not accessing the correct bar

[CaptainAmericaXX]

Hello,
I've got a weird problem (at least I think it's weird).
In a separate file I have:

//beginBluePeriod
        if(CrossAbove(stoch.K, 50, 1)){
            beginBluePeriod        = CurrentBar;
        }
        //Set IntSeries
        beginUpPeriod.Set(beginBluePeriod);

In my indicator file I have:

if(stochDirection.DownPeriod[0]){
            //Find highest value of blue period    
            sd_HighestHigh_Bar       = HighestBar(High, (CurrentBar - stochDirection.BeginUpPeriod[0]));    
            sd_HighestHigh_Value    = High[sd_HighestHigh_Bar];     
            }

Everything works fine except when the "beginBluePeriod" condition is only true for one bar. When this happens

sd_HighestHigh_Bar        = HighestBar(High, (CurrentBar - stochDirection.BeginUpPeriod[0]));

will return 0 instead of 1. So I get the wrong High.
When I Print();

Print("BarNumber = " + (CurrentBar - stochDirection.BeginUpPeriod[0]));

BarNumber returns 1.
I have verified that stochDirection.BeginUpPeriod[0] is starting on the proper bar.
Again this ONLY happens when the beginBluePeriod condition is only true for one bar.
Any help would be much appreciated!

Hello CaptainAmericaXX,

Thanks for your post.

Keep in mind that

 
 (CurrentBar - stochDirection.BeginUpPeriod[0])

is not the same thing as

 
 HighestBar(High, (CurrentBar - stochDirection.BeginUpPeriod[0]));

If you print HighestBar(High, 1) you will always get 0. You could branch your logic when (CurrentBar - stochDirection.BeginUpPeriod[0]) == 1 as a way to move forward so the logic you are using does not skew your calculation.

Lets us know if we can be of further assistance.

Thank you Jim,
I've had this issue a lot. I needed to read the documentation more clearly. It says,

period: Number of bars to include in the calculation

So obviously 1 is going to return the current bar. I was figuring a return value of 0 would return the current bar.
Just to restate so I'm clear. So when

CurrentBar - stochDirection.BeginUpPeriod[0]

returns 1 then

HighestBar(High, (CurrentBar - stochDirection.BeginUpPeriod[0]))

will return the current bar since there is 1 bar to consider in the period.
Thanks for the clarification! Thank you also for the fix suggestion.
