Change in open interest

Sun, 21 Jun 2026 00:00:00 +0000

Change in open interest is the net number of futures and options contracts added or removed over a chosen period, measured against a reference point such as the previous close or the start of the trading session. Where open interest is the standing level of live contracts reported by the National Stock Exchange , the change is the flow into or out of that level, and it is the flow that tells a trader whether positions are being built or unwound right now.

How to place an order without adding to a marketwatch on Kite

Sun, 21 Jun 2026 00:00:00 +0000

You can place a buy or sell order on Kite , Zerodha’s trading platform, without first adding the instrument to a marketwatch . The marketwatch is a watchlist for tracking live prices, not a precondition for trading. Kite opens an order ticket for any tradable instrument straight from universal search, from your Holdings tab, from your Positions tab, or from the option chain, and you submit the order without the instrument ever entering a list.

Strike selection on the option chain

Sun, 21 Jun 2026 00:00:00 +0000

Strike selection is the choice of which option strike to trade, made by weighing the strike’s delta and its implied probability of expiring in-the-money, its liquidity as shown by open interest and volume, the risk-reward of the position, and the tradeoff between in-the-money, at-the-money and out-of-the-money moneyness . On Zerodha it is done by reading the Kite option chain, which lists every listed strike with its open interest, volume, implied volatility and, in the Greeks tab, its delta and the other Greeks. The strike a trader picks fixes the cost, the leverage, the probability of profit and the risk profile of the whole position.
