Tomasz,
I will agree now.
The solution you provide here [OHLCV substitution in fact] is much
better than the analytic one you provided at
http://groups.yahoo.com/group/amibroker/message/40009
and does not need deeper indicator formula understanding.
Of course, it is always better to know full details, but it does not
match to all users preferences.
It wouldn΄t be bad to add this general example in some next Users
Guide, it may solve the majority of comparison problems.
