[amibroker] How to set different exit for different buying rules?

[Louis Préfontaine]

Hi,

I am trying to set two rules.  I want that if the system buys when rule 1 it
exits after 4 days, and if it buys when rule 2 it exits after 2 days.  I
already know how to do for one simple rule
(
Buy = ExRemSpan (Buy, 4);
Sell = Ref (Buy,-4);


)

but I'd like to set a different exit for each rule.

Anyone know how to do this?

Thanks,

Louis
