What Are Directional Events?
Directional events have multiple instruments with ordered strike levels where outcomes are logically linked. If a higher threshold is true, all lower thresholds must also be true. Examples include:- Point spreads: Will the team win by more than 3.5? More than 6.5? More than 10.5?
- Totals: Will the combined score exceed 40.5? Exceed 47.5? Exceed 50.5?
Whether an event is directional is a property of how the exchange lists it, not of the question. Sports spread and total ladders are listed as directional events. Crypto Above/Below and One-Touch ladders are currently listed as independent events and do not receive directional collateral return; crypto Price Range ladders are mutually exclusive events and receive Mutually Exclusive Collateral Return instead. See Crypto Schema.
How Collateral Return Works
When collateral return is enabled on your account and you hold a lower-ranked long position that offsets a higher-ranked short position in the same directional event, your margin requirement is reduced. Consider a spread ladder on one NFL game with three instruments, each paying out if the Chiefs win by more than the stated margin. Theneg- symbols are the Chiefs laying points: neg-3pt5 is the Chiefs at -3.5, so the larger the number, the harder the question and the higher the rank.
If the Chiefs win by more than 10.5, they also won by more than 6.5 and 3.5. This directional relationship is what enables collateral return.
Without Collateral Return:
- long 3 contracts of
asc-nfl-kc-phi-2026-02-09-neg-3pt5 - short 2 contracts of
asc-nfl-kc-phi-2026-02-09-neg-6pt5 - Margin requirement: 2 (full short position)
- Buying power reduced by 2
- long 3 contracts of
asc-nfl-kc-phi-2026-02-09-neg-3pt5 - short 2 contracts of
asc-nfl-kc-phi-2026-02-09-neg-6pt5 - Margin requirement: 0 (short fully offset by lower-ranked long)
- Buying power: no reduction
Why This Matters
Your long position at the lower threshold guarantees a payout in any scenario where your short position at the higher threshold loses. If the Chiefs win by more than 6.5 (your short loses), they also won by more than 3.5 (your long wins), so the long payout covers the short’s loss. Maximum loss calculation:- Chiefs win by 3.5 or less, or lose: Long loses, short wins = net depends on entry prices
- Chiefs win by more than 3.5 but not more than 6.5: Both positions win
- Chiefs win by more than 6.5: Long wins, short loses - but long payout offsets short loss
Directionality Matters
Only a lower-ranked long can offset a higher-ranked short. The reverse does not work.- long
asc-nfl-kc-phi-2026-02-09-neg-3pt5, shortasc-nfl-kc-phi-2026-02-09-neg-6pt5- collateral return applies - long
asc-nfl-kc-phi-2026-02-09-neg-6pt5, shortasc-nfl-kc-phi-2026-02-09-neg-3pt5- NO collateral return
Multiple Offsets
A single lower-ranked long position can offset multiple higher-ranked short positions. Using the same ladder with more thresholds:- long 10 contracts of
asc-nfl-kc-phi-2026-02-09-neg-3pt5 - short 2 contracts of
asc-nfl-kc-phi-2026-02-09-neg-6pt5 - short 3 contracts of
asc-nfl-kc-phi-2026-02-09-neg-10pt5 - short 6 contracts of
asc-nfl-kc-phi-2026-02-09-neg-13pt5 - Total short: 11, Collateral return: 10 (2 + 3 + 5 from remaining long)
- Margin requirement: 1
Using Freed-Up Buying Power
Freed-up buying power can be deployed into other markets (different events). This allows for more efficient capital utilization across your entire portfolio. However, you cannot use this freed-up buying power to increase your position in the same directional event that generated the collateral return.Closing Offsetting Positions
When you close one of the offsetting positions, you must “return” the collateral that was freed up. Example:- You are long 3 contracts of
asc-nfl-kc-phi-2026-02-09-neg-3pt5, short 2 contracts ofasc-nfl-kc-phi-2026-02-09-neg-6pt5(collateral return of 2) - You use that freed buying power to trade in a different market
- If you try to sell your long position, you must return the collateral
- If that buying power is already deployed elsewhere, the order will be rejected
Key Points
- Collateral return applies to directional events where lower thresholds must be true if higher ones are
- A lower-ranked long offsets a higher-ranked short (not the reverse)
- One long position can offset multiple short positions across higher ranks
- Freed-up buying power can be used in other markets, not the same event
- Closing offsetting positions requires returning the freed collateral
- This is a portfolio margin optimization, not a reduction in actual risk
