This occurred to me, but that would not explain why it works as an indicator.
Those variables remain constant when the code is used standalone.
There is more going on here than I understand or I am making an error. Try this
one and see if anyone has an explanation. Following is code for a daily average
plotted on an intraday chart, I am looking at a 30 min ES chart. When you first
drop this code on to a 30 min ES chart, notice where the average is, then
change the price parameter from close to average. The average will move. Then
set the price parameter back to close. It will move again but not back to where
it was originally. I believe, that when first dropped onto the chart it is
looking at the 30 minute closes. Once the parameter is changed it is looking at
previous daily closes. I determined this by reducing the average to 2 to
simplify the math.
I am doing somthing wrong, but I don't know what. Code for daily average
plotted on a shorter duration chart:
SetFormulaName("Daily Expanded MA");
//Daily moving average plotted on shorter duration charts
TimeFrameSet( inDaily);
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10);
DailyMa = MA(P,Periods);
TimeFrameRestore();
eDailyMA = TimeFrameExpand( DailyMA, inDaily); // expand for display
Plot( eDailyMA, "Daily Average", ParamColor( "Color", colorCycle ),
ParamStyle("Style") );

I haven't done any work with multiple time frames. So, this is just a guess.
But, if you are referring to the values being printed out, it looks like you
would have to use TimeFrameExpand in your output statements:
e.g.
"RPHigh: "+ NumToStr( TimeFrameExpand( RPHigh, ...), 1.4);
