[amibroker] Re: Translating a simple system

Ok Graham and Mike - I just got a note from my friend saying I'm not
interpreting one of the rules correctly - the correct rule is:

The distance from the 10 day ma is the largest since the equity began
trading below the 10d ma (rather than largest it has been in the last
10 days).

So I can't use the sum command in this case because it requires a
period - could I count the period using code like this?

IIf(C<MAshort,Daysbelow = Daysbelow +1,Daysbelow);

Thoughts appreciated.
