OBV more often than not gives clean breakouts and dictates the market direction. I was pitying people who were buying puts for every 50 pts. rise. When the BN future started trading in discount, i remember i had sold 22000PE around 550 on friday and covered it today because of the confidence which OBV gave me. The OBV largely represents the serious market participants and their chartered course. Now you all tell me what else is left to teach about OBV. It is as simple as trading the BO/BD of OBV. You do not need rules or a method for it. Sure SL may hit but then it hits, what can one do about it.
