I am having a similar problem. I created the following code as an indicator and it works perfectly. However, when I copy code into a larger system, I get different values. The problem is once copied into the system, RPHigh, RPLow, and RPClose change values starting at the last bar in a 30 minute chart and going back 7 bars. As a stand alone indicator they remain constant. Any ideas why this is happening? - James

SetFormulaName ("Rolling Pivot");

TimeFrameSet( inDaily );

RollPer = Param("Rolling Period", 3, 1, 20, 1);
RPHigh = HHV(Ref(H,-1),RollPer);
RPLow = LLV(Ref(L,-1),RollPer);
RPClose = Ref(C,-1);
RPivot = (RPHigh + RPLow + RPClose)/3;
TimeFrameRestore();

eRPivot = TimeFrameExpand( Rpivot, inDaily, expandFirst); // expand for display

"RPHigh: " + NumToStr( RPHigh, 1.4 );
"RPLow: " + NumToStr( RPLow, 1.4 );
"RPClose: " + NumToStr( RPClose, 1.4 );
"Rolling Pivot: " + NumToStr( RPivot, 1.4 );
"eRPivot: " + NumToStr (eRPivot, 1.4 );

Plot(eRPivot,"Rolling Pivot",colorLightGrey);

hi,

not sure if I completely understand myself but adding expandFirst removes this problem, see below, rgds, Ed

TimeFrameSet(inDaily);
inside_d = Inside();
TimeFrameRestore();

kk = TimeFrameExpand(inside_d, inDaily,expandFirst);

Plot(kk, "daily inside", colorWhite,styleHistogram);

"Inside bar: " + WriteVal(kk);

if(Status("action") == actionCommentary)
{
printf("inside_d: %g\n", kk);
}

I've come back to this issue, and still am unable to figure out why
this is happening. Why would the plot on the chart return a different
value than the interpretation window? I greatly appreciate any help.
