Re: [amibroker] How to filter during scan?

[Graham <kavemanperth@xxxxxxxxx>]

yes, you just include whatever conditions you require
One suggestion is to only have price conditions for the buy and short
as the exits do not require this condition. especially shorting hwere
you want the exit to be much lower than the entry price

Filter is only used for explorations, nothing else
