What is a Ratio Spread? A Simple Guide
A ratio spread is an options strategy where you buy and sell options in an unequal ratio, commonly buying one and selling two at a different strike. It can be entered cheaply or even for a credit. The extra short option reshapes the payoff and reopens risk on a strong move.
A ratio spread is an advanced strategy that tilts the odds by selling more options than it buys. It can be low-cost, but the extra short option adds real risk.
The sections below explain it step by step, without the jargon. You can trade it on Stockk.
Key Takeaways
- It buys and sells options in an unequal ratio.
- Commonly one bought, two sold at a higher strike.
- It can be entered cheaply or for a credit.
- A strong move reopens open-ended risk.
- It is an advanced, not a beginner, strategy.
How does a ratio spread work?
Consider a case where NIFTY trades at 22,600. You buy one 22,600 call at ₹180 and sell two 22,800 calls at ₹95 each, so the position starts with a small ₹10 credit. Profit peaks at ₹210 if NIFTY finishes at 22,800. Beyond that the extra short call takes over, and above the upper breakeven of 23,010 the loss grows without limit on a strong rally.
Why it can be risky
Selling more options than you buy collects extra premium, which can fund the long option or create a net credit. This produces a profit zone but leaves one or more uncovered short options, so a strong move beyond the short strikes reopens risk. The payoff is favourable in a range but dangerous on a large move.
When it profits and when it hurts
| Scenario | Outcome |
|---|---|
| Price stays in the zone | Profit |
| Price moves mildly | Small gain or loss |
| Price moves strongly | Open-ended risk reopens |
Why it needs experience
Because the short options outnumber the long ones, a sharp move in the direction of the extra shorts creates open-ended risk on that side. The strategy looks attractive in calm conditions but can produce large losses if the underlying trends strongly. It demands careful risk management and is not a beginner strategy.

What defines a ratio spread?
It buys and sells options in an unequal ratio, often one long and two short, and the extra short reshapes the payoff. It can be low-cost or a credit.

The uncovered extra short option creates open-ended risk on a strong move. Calm markets are fine; trends are dangerous.
