Re: [amibroker] Question re price field parameter, AmiBroker Email List Archive

Thank you Steve, you are absolutely correct. This was causing problems on my expanded daily average. On the code below, the different closes were calculating different averages, not sure why - since it is operating in inDailytime frame, there should only be a daily close. Perhaps the initialized value overides TimeFrameSet.

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 believe that TJ initializes his ParamField variable to -1, which is the first plot on the chart, and that name is added at the bottom of the param list. Try editing the default name of the original price plot to "TEST" to see what I mean.

Can someone please verify if this is just happening to me? Just drop the Amibroker simple MA from the charts onto a price chart and see if there are two Close in the price field parameter drop down box. If this is normal, why are there two close fields to choose from?

I have found that if I drop a moving average into a price chart, I am getting two "Close" in the price field parameter. Can anyone confirm they are seeing the same and if so explain why there are 2 "Close" price fields?

This does not cause a problem until I start using formulas that use setTimeFrame.
