cockeyedcowboy,

I finally found the array problem. The below code did not an appropriate shift in the formula. I have now changed this so that it reflects "i".

FastMA[ i ] = iMAOnArray( vol, 0, 14, 0, MODE_SMA, i );
SlowMA[ i ] = iMAOnArray( vol, 0, 21, 0, MODE_SMA, i );

Thank you for your help.
