Nifty 50 is now forming a symmetrical triangle pattern meaning the volatility will be contracting while price moves inside this pattern and when the price comes out of this pattern then there will emerge a new stronger trend.
The price is now in range between 37700 and 34100. If price crossed this Blue trendline and closes strongly above it with good volume in 1hr Time Frame then one can expect a further upmove in NiftyBank.
Whenever the price reaches this Trendline region supply comes in and the price falls down. One should wait for NIFTY to strongly close above 17640 (with wide range candle with volume expansion) to go Long.
