I am using the 1H/4H for positional trades. The 3EMA just touched/marginal crossover the 15EMA around the close in 1H and the 4H still shows 3EMA below 15EMA, so went short with one lot of NIFTY futures. Will have stoploss of 10 points. Feel since it is expiry, it could be volatile and there will be many crossovers in hourly chart. So need to try and avoid trading for positional this week.
