Quick Answer
The put ratio backspread Nifty IT sells one put at a higher strike and buys a larger number of puts, typically two, at a lower strike, on the same expiry. This is the mirror image of the call ratio backspread, applied to the downside instead of the upside. With Nifty IT at Rs 38,548, the put ratio backspread Nifty IT has a defined maximum loss that occurs at or near the lower strike, but substantial profit potential, limited only by the index falling to zero, if Nifty IT declines significantly beyond that point, since the extra long put has no offsetting short put. The put ratio backspread Nifty IT may be considered when a trader expects either a large decline or, in some structures, is comfortable profiting modestly if the index stays flat or rises, depending on whether the position is entered for a credit.
The this strategy inverts the logic of a simple bear put spread: instead of buying and selling an equal number of puts, it buys more puts than it sells. This shifts the exposure so that a large decline in Nifty IT produces substantial profit, while the loss is capped at a specific, calculable level in the middle zone between the strikes.
Because the put ratio backspread Nifty IT buys more options than it sells, it is often structured for a smaller net debit, and in some cases even a net credit, depending on the strikes and the implied volatility skew between them, which is often more pronounced on the put side of the index options market.

What Is the The position?
The put ratio backspread Nifty IT is a multi leg options strategy that sells puts at one strike and buys a larger number of puts at a lower strike, all on the same expiry. The most common version, the 1 by 2 this trade, sells one put and buys two puts.
The legs of a 1 by 2 put ratio backspread Nifty IT are:
- Sell one put at the higher strike, generating premium and defining part of the risk profile
- Buy two puts at the lower strike, providing substantial downside exposure through the uncovered extra long put
The first bought put is offset by the short put, forming a standard vertical spread in reverse. The second bought put is uncovered on the downside, meaning the this options approach carries substantial profit potential if the index declines significantly, similar to holding an extra outright long put beyond the vertical spread structure.
How Does the Put Ratio Backspread Nifty IT Work?
With Nifty IT at Rs 38,548, a 1 by 2 the spread might sell a put near 38,500 and buy two puts near 38,250. Between the two strikes, the position can show its maximum loss, but beyond the long strike, the uncovered extra long put drives substantial profit potential as Nifty IT continues to fall.

When NOT to Use the Put Ratio Backspread Nifty IT
Consider avoiding the put ratio backspread Nifty IT when you expect the index to move moderately rather than dramatically, since the maximum loss zone sits precisely in that moderate range; when implied volatility is very high, making the long put leg expensive; or when you are not comfortable managing a three leg position with a non intuitive payoff shape.

Because the worst outcome occurs in the middle zone rather than at either extreme, traders should understand this non intuitive payoff shape before entering the put ratio backspread Nifty IT and plan exits accordingly if the index approaches the long strike without breaking through it.
Transaction Costs
The put ratio backspread Nifty IT involves three option contracts (one short, two long in a 1 by 2 ratio), each with its own transaction costs. Brokerage, exchange transaction charges, STT, GST, SEBI charges, stamp duty, and bid ask spread impact across three legs should be weighed against the net credit or debit involved.
