[amibroker] Re: Variable periods

Stephane,
thank you for pointing this out.
The variable StochD() period may be solved through the analytic StochD
() expression.
The peculiar thing is that the parts of this analytic expression 
[HHV, LLV and MA] *do* accept variable period, their result does 
not !!
