Tomasz,
I decided to look into this closer.
While this is true that an "indicator":
10 OR 20 OR 30
- in Metastock returns 1,
an indicator graph0=(10 OR 20 OR 30) in Amibroker returns 10.
(50 OR 20 OR 30) = 50, etc.
I have to say I am totally surprised by this outcome.
Also
aa=(10 OR 14 OR 18);
graph0=RSI(aa)>50
is not equal to
graph0=RSI( 1 ) > 50
but something else. I think RSI(10)>50, but I know much too little of
Amibroker to tell.
Thank you. Best regards
Yarroll
