The highest call OI is at 15000 strike price - that will act as resistance and may attract the price towards that. If it's taken out we may see some good upside
Interestingly 14800 strike price has 3.1M call OI and 2.6M put OI - so that has also got good potential to attract price towards it
Expiry Trade Strategy
Either short a straddle at the opening price for today and keep 25% as SL or wait for either side movement up / below the black resistance line
