Re: [amibroker] what's wrong with the codes? ---compare to index's daily EMA

You are using Ind_EMA for the copmressed as well as the expanded variables.

Use:
Daily_EMA= TimeFrameExpand(Ind_EMA, inDaily, expandLast);

Also remove your "TimeFrameSet (in5Minute);".

You don't need it.

Subject: [amibroker] what's wrong with the codes? ---compare to index's
daily EMA


Hello,

   I have an intraday database composed of 5-min data. I lilke to
know index's EMA (15 days) for each stock. For example, today is
5/25/06, for each stock, I like to know the index's (INX in my case)
EMA of past 15 days (not including 5/25/06).

  The following are the codes I wrote. However, it does not return
the right number. What is wrong?

   Thank you very much!

TimeFrameSet (inDaily);


Ind_close=Foreign("INX","Close");


Ind_EMA=EMA(Ind_close,15);


TimeFrameRestore ();


TimeFrameSet (in5Minute);

Ind_EMA= TimeFrameExpand(Ind_EMA, inDaily, expandLast);

AddColumn(Ind_EMA, "Ind_EMA");

Filter=C>0;
