DF Double Butterfly

Spread

SecuritySubTypeSpread type = DF


The A Double Butterfly (DF) spread is a "calendar" spread between two future butterfly strategies where one butterfly is bought and a deferred month butterfly is sold. The second and third leg of the first butterfly are identical to the first and second leg of the second butterfly.

The resulting spread consists of positions in 4 equally distributed expiration months within the same product group consistent with the following pattern:

...

Buy 1 double butterfly = buy 1 of the closer expiration leg, sell 3 of the next expiration leg, buy 3 of the next expiration leg, sell 1 of the furthest expiration leg (e.g., Z7-H8-M8-U8).

Double Butterfly is equal to the price of Leg 1, minus the price of three Leg 2's, plus the price of three Leg 3s, minus the price of Leg 4.

Security Definition Example: ES:DF Z8H9M9U9

Example: Buy the Spread

Buy 1 December 2018 Eurodollar

Sell 3 March 2019 Eurodollar

Buy 3 June 2019 Eurodollar

Sell 1 Sept 2019 Eurodollar

Example: Sell the Spread

Sell 1 December 2018 Eurodollar

Buy 3 March 2019 Eurodollar

Sell 3 June 2019 Eurodollar

Buy 1 Sept 2019 Eurodollar  is composed of two different Butterfly spreads with the nearest Butterfly expiration purchased (sold) and the furthest Butterfly expiration sold (purchased). The spacing of expirations in both Butterfly spreads needs to be identical, i.e. both need to be “three month” Butterflies. This causes the actual construction of the Double Fly to look like this:

Buy (sell) one of the nearest expiration, sell (buy) three of the second nearest expiration, buy (sell) three of the third nearest expiration, and sell (buy) one of the most deferred expiration.


A Double Butterfly has:

  • One Product
  • four legs
    • Leg1 (buy leg) must be the nearest expiration
    • Leg2 (sell leg) must be the next nearest expiration
    • Leg3 (buy leg) must be the third nearest expiration
    • Leg4 (sell leg) must be the most deferred expiration
  • Quantity/side ratio of the legs is +1:-3:+3:-1
  • Expiration sequencing for Double Butterfly:
    • Leg1 month < Leg2 month < Leg3 month < Leg4 month
    • In addition, expiration differentials must be sequential and equal, i.e. if Leg1 expires in June and Leg2 expires in Sept., the next two legs must have an expiration differential of three months as well, so Leg3 must expire in Dec. and Leg4 must expire in March of the next year (see symbol below for an example of this)

Example: Instrument Symbol = GE:DF M9U9Z9H0

  • Leg1 = +1 GEM9
  • Leg2 = -3 GEU9
  • Leg3 = +3 GEZ9
  • Leg4 = -1 GEH0
  • Buying a Double Butterfly buys leg1, sells three of leg2, buys three off leg3, sells leg4
  • Selling a Double Butterfly sells leg1, buys three of leg2, sells three off leg3, buys leg4
Info
This spread can trade at zero and at a negative price.

Pricing

  • The Double Butterfly Trade Price is = Leg1 – (3 * Leg2) + (3 * Leg3) – Leg4


Leg Price Assignment

  • Leg1, leg2 and leg3 are assigned most recent price update  
  • Leg4 is calculated using the differential of the traded spread price:
    • Leg1 – (3 * Leg2) + (3 * Leg3) – Trade Price
  • If leg4 price is outside the daily limits, Leg4 will be adjusted to daily limit and Leg1 is recalculated
    • Leg1 = Trade Price + (3 * Leg2) - (3 * Leg3) +Leg4
Info
If leg1 recalculated price is outside the daily limit the price will stand.  Customers can receive a non-settled price for the recalculated leg.


Pricing Examples

  • Leg1 = 9812.5
  • Leg2 = 9857.5
  • Leg3 = 9857.0
  • Leg4 is calculated:
    • 9812.5 – (3 * 9857.5) + (3 * 9857.0) – 13.5
    • Leg4 = 9797.5


Pricing Example Legs Calculated Outside of Daily Limits

Leg4 outside daily limit; leg4 reset to daily limit and leg1 is recalculated

Double Butterfly trades at 13.5

  • Leg1 has a calculated price:
    • Leg1 = Trade Price + (3 * Leg2) - (3 * Leg3) +Leg4
    • Leg1 = 13.5 +29572.5 – 29571.0 + 9797.5
    • Leg1 = 9812.5

  • Leg3 = 9857.0
  • Leg4 = 9797.5

  • Leg4 is calculated:
      • Leg1 = Trade Price + leg2 + leg3 – leg4
    • If leg1 has a calculated price outside of the daily limit, leg1 is adjusted to daily limit and leg2 price is recalculated
      • Leg2 = leg1 – leg3 + leg4 – Trade Price
    • If leg2 has a calculated price outside the daily limits, leg2 will be adjusted to the daily limit and leg3 recalculated
      • Leg3 = leg1 - leg2 + leg4 – Trade Price
    • Trade Price – Leg1 + Leg2 + Leg3
    • If leg4 price is outside the daily limits, Leg4 will be adjusted to daily limit and Leg1 is recalculated
Info
If leg3 has a recalculated price is outside the daily limit the price will stand. Customers can receive a non-settled price for the recalculated leg.
