Re: [amibroker] BarsSince(Buy)

["Tomasz Janeczko" <amibroker@xxxxxx>]

Hello,

The answer is in the User's Guide:
http://www.amibroker.com/guide/h_understandafl.html

Hint: all arrays are processed at once and your BarsSince(Buy) is effectivelly
BarsSince(False).

You can use ExRemSpan instead:

Buy = Cross( RSI(3), 47 );
Buy = ExRemSpan( Buy, 10 );

Sell = Cross( 52, RSI(3)) AND BarsSince( Buy ) > 10;
Sell = ExRemSpan( Sell, 10 );


Best regards,
