The boundary values are in fact contained in the contract symbol in a shorthand format. The bounds are always denominated in the same currency as the quoted prices.  Follow the below formulas to calculate the boundary value for a given contract root symbol.


BB (Bounded Bitcoin)

  • Multiply the boundary values in the symbol by 1,000


BE (Bounded Ether)

  • Multiply the boundary values in the symbol by 100


BEB (Bounded ETH/BTC)

  • Divide the boundary values in the symbol by 100


Symbol structure:

[product][expiry] L[lower boundary]U[upper boundary]


Examples: 

  • BBW52 L36U60

    • L36 * 1,000 = 36,000

    • U60 * 1,000 = 60,000

  • BEW52 L27U53

    • L27 * 100 = 2,700

    • U53 * 100 = 5,300

  • BEBW52 L6U11

    • L6 / 100 = .06

    • U11 /100 = .11
