Ravi bhai BNF is incredibly difficult to trade due to very high volatility. Due to this I have completely shunned it. Similarly I'm avoiding Nifty futures for the past few months. I have shifted to stock futures which are enough volatile and easy to trade in a bull market. Presently I trade only in Jet, RIL and ITC futures. You should also try stock futures for a change. Money rains in them very easily.
