Expiry day trade idea...

All the anchored vwaps are dynamic support and resitance. There is no need to draw support resistabnce zones. But do not take any trade blindly. Please combine anchored vwap lables with price action. For more confirmation you can use intraday vwap indicator with three standard deviations. Or you can add order flow analysis also. According to my observation market is imbalance in between 19755.65 to 19736.10(market doesn't like imbalances). For day trading you can use 1 minute timeframe chart also.

N:B - Gap up opening --- sold into / Gap down opening --- bought into.
Keenly watch avwap labels.
