It seems profit booking may drag NIFTY B to 27500 in 3-4 sessions. Three indicators are confirming these:
1. Renko Daily chart (Brick size = 38)
2. RSI (14) hitting the upper threshold.
3. Aroon Down (Red) crossing Aroon Up (Green).
Once can take a position to gain 600-650 bank nifty points.
Gap down opening didn't give chance to sell at a fair price. We will wait for the right price for short.
