You are an options trading expert specializing in classifying complex multi-leg options strategies.
Classify the following options trading position into one of the following types:

- Butterfly: A 4-leg strategy that can be constructed using either all calls or all puts. It involves buying one option at one strike (OTM/ITM), selling two options at a closer ATM strike, and buying one option at another farther strike (OTM/ITM), all with the same expiration. This creates a neutral strategy focused on low volatility.
- Calendar: A 2-leg strategy, selling a shorter-term option and buying a longer-term option at the same strike (ITM/ATM/OTM).
- Double Calendar: A 4-leg strategy involving both calls and puts. The strike prices for the sell and buy put match, and the strike prices for the sell and buy call match, but the sell options have a shorter expiration date than the buy options. This creates a time-based strategy with matching strikes and different expirations.
- Double Diagonal: A 4-leg strategy involving both calls and puts, where the strike prices for the puts and calls do not match (i.e., sell and buy options are at different strikes), and the sell options have a shorter expiration date than the buy options. This structure is similar to a Double Calendar but with diagonal strike relationships.
- Iron Condor: A 4-leg strategy involving selling an OTM put and an OTM call, while buying further OTM put and call options, all with the same expiration.
- Iron Fly (Iron Butterfly): A 4-leg strategy involving selling an ATM straddle (a call and a put at the same ATM strike), and buying an OTM call and an OTM put to hedge risk, all with the same expiration.
- Jade Lizard: A 3-leg strategy involving selling a put spread (OTM/ITM) and selling an OTM call to capture premium while limiting upside risk.
- Long Call: A single-leg strategy involving buying one OTM/ITM/ATM call option.
- Long Call Spread: A 2-leg strategy involving buying a call option at one strike (OTM/ITM) and selling a call at a higher OTM strike, both with the same expiration.
- Long Put: A single-leg strategy involving buying one OTM/ITM/ATM put option.
- Long Put Spread: A 2-leg strategy involving buying a put option at a higher strike (OTM/ITM) and selling a put at a lower OTM strike, both with the same expiration.
- Ratio Spread: A strategy involving selling more options (OTM/ATM/ITM) than are bought, with different strike prices.
- Short Call: A single-leg strategy involving selling one OTM/ITM/ATM call option.
- Short Call Spread: A 2-leg strategy involving selling a call option (ATM/OTM) and buying a call at a higher OTM strike, both with the same expiration.
- Short Put: A single-leg strategy involving selling one OTM/ITM/ATM put option.
- Short Put Spread: A 2-leg strategy involving selling a put option (ATM/OTM) and buying a put at a lower OTM strike, both with the same expiration.
- Short Straddle: A 2-leg strategy involving selling a call and a put at the same ATM strike and expiration.
- Short Strangle: A 2-leg strategy involving selling an OTM call and an OTM put with the same expiration.

Important: When classifying the strategy, compare puts with puts and calls with calls in terms of strike relationships and expiration dates.


Classify the following position (compare strikes and expiration dates of puts vs. puts and calls vs. calls separately):

Total of 3 legs
Leg 1: Sell 10 P options atm
Leg 2: Buy 20 P options otm
Leg 3: Buy 10 P options otm
Leg 1 strike is greater than Leg 2 strike
Leg 1 expiration date is greater to Leg 2 expiration date
Leg 1 strike is greater than Leg 3 strike
Leg 1 expiration date is equal to Leg 3 expiration date
Leg 2 strike is equal than Leg 3 strike
Leg 2 expiration date is less to Leg 3 expiration date
