A combo, also called a strategy, combines two or more related instruments (legs) into a single trade, such as call spreads, put spreads, and calendar spreads.

Combo book summary

  • Easier execution: Execute all legs of a multi-leg option strategy with one order at one price, instead of managing multiple orders.

  • No leg risk: All legs of a combo fill together, so one leg can't fill while the price moves away from the other.

  • Flexible legs: After a position opens, trade each leg individually in its own order book or as part of a different combo.

  • Small minimum sizes: The minimum trade size for a combo matches the options it contains, for example 0.01 BTC, 0.1 ETH, 10 SOL (1 contract), or 1,000 XRP (1 contract).

Combo lifetime

The number of option combo order books that can be active at the same time is limited for each underlying asset. The soft and hard limits apply across the whole exchange. The limit on creating new combos applies to each account.

  • Above the soft limit: combos that don't meet the 2-hour volume threshold are deactivated, starting with the lowest 2-hour volume.

  • At the hard limit: no new combos can be created until the system deactivates others.

  • Combos newer than 2 hours aren't deactivated.

In the tables below:

  • Higher and lower describe each strike compared with the other legs.

  • Legs when you buy 1 shows what one combo contains when purchased. 

    • Selling the combo reverses every leg.

Vertical spreads examples

Strategy

Description

Legs when you buy 1

Call spread

Costs less than buying a call on its own, but caps the potential gain. Often used when expecting a moderate rise.

Buy 1 call, sell 1 call at a higher strike, same expiry

Put spread

Costs less than buying a put on its own, but caps the potential gain. Often used when expecting a moderate fall.

Buy 1 put, sell 1 put at a lower strike, same expiry

Risk reversal

Gains if the price falls, paid for by selling a call. The short call carries unlimited risk if the price rises.

Buy 1 put, sell 1 call at a higher strike, same expiry

Risk reversal (ITM)

Gains if the price rises, paid for by selling a put. Both options are in the money. The short put carries significant risk if the price falls.

Buy 1 call, sell 1 put at a higher strike, same expiry

Ratio spreads and ladders examples

Strategy

Description

Legs when you buy 1

Call ratio spread 1×2

Selling extra calls lowers the cost and can bring in premium. Losses can grow without limit if the price rises sharply.

Buy 1 call, sell 2 calls at a higher strike, same expiry

Call ratio spread 1×3

Same as 1×2 with one more short call, so more premium. Losses can grow without limit if the price rises sharply.

Buy 1 call, sell 3 calls at a higher strike, same expiry

Call ratio spread 2×3

A milder ratio (1 to 1.5). Losses can grow without limit if the price rises sharply.

Buy 2 calls, sell 3 calls at a higher strike, same expiry

Put ratio spread 1×2

Selling extra puts lowers the cost and can bring in premium. Losses can be large if the price falls sharply.

Buy 1 put, sell 2 puts at a lower strike, same expiry

Put ratio spread 1×3

Same as 1×2 with one more short put, so more premium. Losses can be large if the price falls sharply.

Buy 1 put, sell 3 puts at a lower strike, same expiry

Put ratio spread 2×3

A milder ratio (1 to 1.5). Losses can be large if the price falls sharply.

Buy 2 puts, sell 3 puts at a lower strike, same expiry

Call ladder

A call spread plus an extra short call at a higher strike, which lowers the cost. Losses can grow without limit if the price rises far above the highest strike.

Buy 1 call, sell 1 call at a higher strike, sell 1 call at an even higher strike, same expiry

Put ladder

A put spread plus an extra short put at a lower strike, which lowers the cost. Losses grow if the price falls far below the lowest strike.

Buy 1 put, sell 1 put at a lower strike, sell 1 put at an even lower strike, same expiry

Volatility combo examples

Strategy

Description

Legs when you buy 1

Straddle

Can gain from a large move in either direction, but the move must cover both premiums. You can lose the full premium if the price ends near the strike.

Buy 1 call and 1 put at the same strike, same expiry

Strangle

Like a straddle but cheaper, because both options are out of the money. Needs a larger move.

Buy 1 put at a lower strike and 1 call at a higher strike, same expiry

Strangle (ITM)

A strangle built with in-the-money options, so it costs more.

Buy 1 call at a lower strike and 1 put at a higher strike, same expiry

Butterflies and condors examples

Strategy

Description

Legs when you buy 1

Call butterfly

Limited cost and limited gain. The largest gain is when the price is near the middle strike at expiry.

Buy 1 call, sell 2 calls at a higher strike, buy 1 call at an even higher strike, same expiry

Put butterfly

The put version of the call butterfly.

Buy 1 put, sell 2 puts at a higher strike, buy 1 put at an even higher strike, same expiry

Iron butterfly

Selling this combo gives the standard iron butterfly: you receive premium, and the largest gain is when the price ends near the middle strike. Buying it does the reverse.

Sell 1 put, buy 1 call and 1 put at a higher strike, sell 1 call at an even higher strike, same expiry

Skinny call butterfly

A call spread plus an extra long call at the top strike of the combo. You pay premium and can lose all of it. Gains aren't capped if the price rises.

Buy 1 call, sell 1 call at a higher strike, buy 1 call at an even higher strike, same expiry

Skinny put butterfly

A put spread plus an extra long put at the bottom strike of the combo. You pay premium and can lose all of it. The largest gain is if the price falls toward zero.

Buy 1 put, sell 1 put at a higher strike, buy 1 put at an even higher strike, same expiry

Iron condor

You receive premium. The largest gain is when the price ends between the two middle strikes; the outer options limit the loss.

Buy 1 put, sell 1 put at a higher strike, sell 1 call at a higher strike, buy 1 call at the highest strike, same expiry

Call condor

Limited cost and limited gain. The largest gain is when the price ends between the two middle strikes.

Put condor

The put version of the call condor.

Buy 1 put, sell 1 put at each of the next two higher strikes, buy 1 put at the highest strike, same expiry

Calendar spreads examples

Strategy

Description

Legs when you buy 1

Call calendar spread

Straddle calendar (diagonal)

A straddle calendar with different strikes in each expiry.

Buy 1 straddle at a later expiry, sell 1 straddle at a nearer expiry and a different strike

Synthetic combo examples

Strategy

Description

Legs when you buy 1

Reversal / conversion

Buying creates synthetic long exposure, which moves like a long futures position. Selling creates the opposite (a conversion). Mainly used to trade pricing differences between options and futures. The short put can lose a large amount if the price falls.

Buy 1 call, sell 1 put at the same strike, same expiry

Jelly roll

A synthetic long at one expiry against a synthetic short at another. Used to trade the price difference between the two expiries.
