Strike Selection
Strike selection is choosing which option strike to trade based on delta, cost, probability, and the desired risk-reward.
Picking a strike means balancing trade-offs: at-the-money strikes have high delta and cost, out-of-the-money strikes are cheap with low probability, and in-the-money strikes behave more like the underlying. Sellers often choose strikes by delta (for example a 0.16-delta strike as a rough one-standard-deviation level) to set the odds of expiring out-of-the-money.
Indian traders use the NSE option chain, India VIX, and open-interest walls to pick strikes for Nifty and Bank Nifty trades, matching the strike to their view, time horizon, and risk tolerance. Good strike selection is often the difference between a winning and losing options trade.
