discrepancy
Hello,
For minor (0.001%) differences between
recursively calculated indicators in AA vs IB - see my answer to Fred's
post.
For much bigger differences in OscP as you show
it in your charts: you probably have some different periodicity
setting
or pre/after hours filtering applied to bars or
some other wrong setting because using this code:
Op = OscP( 3,
10 );
Plot( Op, "Op", colorRed );
AddColumn( Op, "Op"
);
Filter=Status("LastBarInRange");
I am NOT getting any difference between AA and
IB
Best regards,

Subject: [amibroker] AA vs. IB
discrepancy
As mentioned in a previous thread, I am getting a
discrepancy between AA and IB for daily mutual fund data, although weekly is
OK. The data is OK with C in all fields. Originally, I thought I
solved the problem by assigning C to O, H, L but upon further checking this
is not correct. No matter what I try the daily AA is different from
the daily IB. The attached gifs show the AA and IB results for the
Price Oscillator.
The formula used for Osc is Osc = 100 *
OscP(3, 10) and the AA filter is Filter =
Status("LastBarInRange").
Would appreciate it if someone would duplicate
what I am getting and, hopefully, find the cause for this discrepancy.
OscP() is a price oscillator calculated by taking the difference
between two moving averages. So why one timeframe works and one does
not is beyond me.
