RE: [amibroker] Easy for experts

Kyle,
 
You would need to use AddToComposite to scan the entire universe (say, of the NYSE) for advances and declines, and create two custom symbols: "~adv" (sum of all advances) and "~dec" (sum of all declies). You can change "~adv" and "~dec" as you wish.
 
Following the AddToComposite run, you can write a new AFL and access (using "Foreign") the three relevant symbols:
(i) "~adv"
(ii) "~dec"
(iii) "SPX" (S&P 500 Index)
 
Once these are accessed, you can easily program any trading idea and backtest/explore it.

Here's the code:

Adv=Close>Ref(Close,-1);
Dec=Close<Ref(Close,-1);

CHADTP=(Sum(Adv,5)-Sum(Dec,5))/5;

How do I write a buy/sell signal with arrows. The signals I want 
are:

When CHADTP > 400 and S&P 500 Close < S&P 500 Close Previous Day 
+.10 = Sell

When CHADTp < 400 and S&P 500 Close > S&P 500 Close Previous Day -
.10 = Buy

This seems so simple to me...I'm just getting caught up. You have 
to run CHADTP against all the constituents in the NYSE and you have 
to reference the S&P 500 at the same time. How do you run the 
scan/explore and simultaneously reference the foreign SPX to get 
arrows on the SPX for trade signals?

Thanks in advance.

Kyle
