Re: [amibroker] A More Efficient Way?

["Ajay Joglekar" <technical.trader@xxxxxxxxx>]

How about this more intuitive code (for me and maybe for most others) by
using Hold instead of Sum. I think Hold is also more efficient than Sum as
it works using boolean calculation rather than arithmatic.

Buy = MA(C,25)>MA(C,75) AND ( NOT  Ref(Hold(MA(C,25)>=MA(C,75),10),-1));

Here you are checking in the second condition that the MA25 was not greater
or equal to MA75 over any of the past 10 days.

Note the use of NOT on the Hold. This will help in similar examples where
you want to have a specific condition true over some past few bars. Then
what you have to do is deduce the exact complement or opposite condition and
put it into Hold , go back as many bars as you want (use Ref) and then NOT
it.
