Nifty future on charts clearly shows an uptrend, however we are not satisfied with volumes. There is always correlation of price action with trading volume, as nifty future price increases volume must also increase accordingly. But this time nifty future is rising and volumes are declining, this is early hint that markets are going to see some downside. Volume often represents confidence, if market is moving higher but confidence is low than sure there will be some problem with trend in short to medium term. Traders need to patiently wait for some slow down in momentum to add some short position in nifty future current series, even slowdown in momentum is sign of trend change.
