Instead of SetForeign use Foreign since you really need only
CLOSE price (not OHLC).
Better yet - use AddToComposite to calculate composite once
only.

Subject: [amibroker] Slow FX Indice code:
can this be improved?
Hi Group
I run the MT3 plugin to get FX data in local
database with local data storage enabled.
This code runs slowly on all
time frames, slowing down AB.
Not being a programmer I wondered if
there was a better way to code this to speed it up a bit.
Code is a
proxy to see which currencies are currently strong or
weak:
********
********
//FX indexes
//
ozzie
SetForeign("AUDJPY"); AJ = C;
SetForeign("AUDUSD"); AU =
C;
SetForeign("AUDCAD"); AC = C;
// EZ
SetForeign("EURUSD"); EU =
C;
SetForeign("EURJPY"); EJ = C;
SetForeign("EURCAD"); ECA =
C;
SetForeign("EURCHF"); ECH = C;
SetForeign("EURGBP"); EG =
C;
// GBP
SetForeign("GBPUSD"); GU =C;
SetForeign("GBPJPY"); GJ =
C;
SetForeign("GBPCHF"); GC =C;
SetForeign("EURGBP"); EG = C;
//
YEN
SetForeign("USDJPY"); UJ = C;
SetForeign("EURJPY"); EJ
=C;
SetForeign("CHFJPY"); CJ =C;
SetForeign("GBPJPY"); GJ =
C;
SetForeign("AUDJPY"); AJ
=C;
RestorePriceArrays();
Pound_Index = GU * GJ * GC *
(1/EG);
OZZIE = AJ * AU * AC;
EZ_Index = EU* EJ * ECA * ECH *
EG;
Yen_Index = -( UJ + EJ + CJ + AJ + GJ);
Plot(OZZIE, "Oz_Index",
colorGreen, 1);
Plot( EZ_Index, "EZ_Index", colorBlue,1 |
styleOwnScale);
Plot( Pound_Index,"GBP Index",colorBlack, 1 |
styleOwnScale);
Plot( Yen_Index, "JPY Index", colorRed, 1 |
styleOwnScale);
*********

While this
computes, AB is pretty much non responsive.
Any
ideas?
