Hello,
TRIN is NOT per index, but per MARKET.
Nasdaq TRIN is calculated out of ALL symbols belonging to NASDAQ market,
not only those in Nasdaq100 index. (of course assuming that you have all Nasdaq stocks in your database).
If you want to calculate TRIN only for Nasdaq100 stocks
you have to move them all to separate "market" using Symbol->Organize assignments.
And of course if your database has only 100 nasdaq stocks you already have TRIN calculated for them.
Best regards,
Tomasz Janeczko
