Now, we may expect a correction or a consolidation phase (expiry day also)
If it makes a confusion candle in 1st 15 minutes, it may be a sideways expiry then. (good for straddle / strangle)
Else wait for consolidation for a while, mark high and lows and may play for breakout or breakdown after 12 PM / 12.30 PM
Probable chart patterns for the above analysis drawn in chart...
Happy Trading !!!
