Market is trending as per previous post. 15450 should be kept as the stop loss in a short term for the long trades. There is a good chance that tomorrow expiry will be around 15600 levels. Shorting monthly options of strike prices below 15300 will be advisable.
Trade as per the risk appetite, Spreads are much better to trade as risk is defined
