Hello Kumudhan
The rules are really very simple . . . look at this as 2 separate methods
1) Based on EMA 200 of OBV & Price . . . Long /Short when price/obv is above/below the EMA
2) Based on breakout/breakdown of Price/OBV
Long when both price and OBV have broken out above their recent high values (15 bars)
Short when both price and OBV have broken down below their recent Low values (15 bars)
the ribbons are just there as visual support tool (bells n whistles)
this is the basics, you can adapt it to your own way of trading
I may not be able to follow up on this conversation, as am on a small chutti . . .
Cheers
Happy
