[amibroker] heikin ashi oscillator

["gonzagags" <gonzagags@xxxxxxxx>]

Hi 
Has anybody read the December Stock commodities article about the
heikin ashi oscillator? 
There is the code for Amibroker, but..
I want to test it buying and selling, and shorting and covering

The orders should be?:
//--------------------------
Haco=Flip(upw,dnw);

Buy=Haco;
Sell=NOT Haco;

Short=NOT Haco;
Cover=Haco;
Buy=ExRem(Buy,Sell); Sell=ExRem(Sell,Buy);
//-----------------------

I have some doubts: does it buy or short one day before it knows the
oscillator is red or green?
How could I take out the so many down arrows?

thanks
