Firstly, in my opinion the Nifty may not crash like the way we saw in March because on the monthly frame I see an inverse Head and Shoulder pattern which is a continuation pattern of the trend.
So basically I don't see a nose dive ,rather a side ways consolidation for a few days/weeks.
Now talking about supports the initial cushion should be around 13265, 13195 and 13026.
If all of them break then we are into a bearish zone and may see further fall.
- Hold on to quality fundamentally good stocks.
- Panic early in the low quality stocks which were taken purely on technical basis as their patterns no longer hold good.
- Sit on cash and wait for your entry in quality stocks with good patterns.
