[amibroker] Re: Counting events in AFL-just learning

["gp_sydney" <gp.investment@xxxxxxxxx>]

Gabe,

Cum() can certainly be used for counting, but from the conditions you
posted, particularly the bit about resetting the count at each new low
trigger point (condition 3), I think you may need to use a loop to do
that.

It may be possible to do it using just array functions, but I can't
think how off the top of my head and it's a relatively simple problem
for a loop.

The problem with using just array functions as I see it is the
iterative nature of the new lows, with each one being based on the
value of the previous one. This means they can't all be determined
independently just from price data, but need to be calculated in order
starting from the first one - ie. you can't determine the third one
until you've already determined the second one. Problems of this
nature are well suited to loops but not to array functions.

Regards,
GP
