Can some kind soul please explain why the iMaOnArray works when first loaded but fails when the timeframe is changed.
Obviously I am missing something?

Inserted Code
int start()
{
   double mPrsCl;
   int mLim, counted_bars = IndicatorCounted();
   ArraySetAsSeries(mMa, true);
   ArraySetAsSeries(mMa2, true);
   
   if(counted_bars > 0)
     mLim = MathMin(Bars, mHist) - (counted_bars - (Bars - mHist));
   if(counted_bars < 0) return(0);
   if(counted_bars == 0)
     mLim = MathMin(Bars, mHist) - 1;

   for(int i = mLim; i >= 0; i--)
   {  
     ....... some code
     mPrsCl = someval; 

      BarCl[i] = mPrsCl;
      if(i < mHist - mMaPrd2 - 1)
       {
         mMa[i]   = iMAOnArray(BarCl, 0, mMaPrd, 0, 1, i);
         mMa2[i]  = iMAOnArray(BarCl, 0, mMaPrd2, 0, 1, i);

       }
   }  
......... more code
    
   return(0);
 }

When the indi is first loaded the Ma's show as expected but once the TF is changed they are there somewhere but the values are '0' or very low.

Any help much appreciated.
TIA

[code]int start()

ArraySetAsSeries(mMa2, true);

if(counted_bars > 0)

for(int i = mLim; i >= 0; i--)

my first guess would be that indicatorcounted doesn't refresh to the whole history on timeframe change. print the value and see what it says when you change tf's so that i don't have to make my own dummy program and check.

also, i'm not confident that having BarCl[i] assignments within the same loop as your nMA# = imaonarray(BarCl calls is such a great idea. i'm not entirely sure what you are trying to achieve because i'm too tired to think about it, but i suspect you might not be setting the values you think you are after you first load this on a chart. unless you have left it sit for awhile and are satisfied that it is indeed doing what you want then if i was you i would rewrite these into separate loops to ensure the entire BarCl array is correctly populated before you go and start making imaonarray calls on it.

edit : plus, you don't show where and how you assign mHist. mHist or IndicatorCounted are the likely problem.
Congratulations ScalaFX for coming out of the closet!

Thanks Nubcake,

mHist was set as an ext var at the start.
I'm not confident that having BarCl[i] assignments within the same loop ....
maybe that is the most likely cause but I have given up on the hassle for now and simply coded my own Ema on the BarCl[] .... it was easier and quicker.

Thanks again,

M.
