The box highlighted in the chart indicates two things
1. Price action: Bullish bars->Explosive candles which indicates strong buying.
2. Every Selling pressure is being absorbed.
3. Above the consolidation range, every rise in buy volume FII's have sold.
4. Price is very strong below 18000 and weak above 18000-18160.
5. A base is being formed and if the price gives a breakout above 18160, then next target is 18280.
Global cues are positive.
NIFTY is gaining strength to break the consolidation but unsure if it can happen before budget.
Unless until it break above 18170 or below 18000 it is good for a quick scalping.
