Amibroker Learning guide

Hi ,

I want some help in learning amibroker programming. I am new in this field, but want to learn how to code . i found that this forum has lots of contents regarding amibroker . Hence taught if someone could guide on how to proceed.

i have learned some simple codes like

X=Cross(EMA(Close,20),EMA(Close,50));
Y=RSI(14)<60;
Buy=X AND Y ;
Sell=Cross(EMA(Close,50),EMA(Close,20));

Here logic is buy when ema 20 cross ema 50 and rsi less than 60 and exit when ema 50 cross ema 20.

when i apply this , i sometimes get sell signals , where there were no buy signal generated in first place . plz someone guide me how to correct it.

Also plz let me know some simple buy sell codes to learn initially .Like the CROSS function is a basic thing and easy to grasp .Likewise plz suggest some simple systems to learn .

Thanks
Deepak.
