Slight correction to this formula, result unchanged (Removed unnecessary x10)
Breakeven funding rates:
If spread = 0 in 20 days
f x 293,500 × 20 = 2,205
f = 2,205/(293,500 x 20)
f = 0.0375%
If spread = 0 in 30 days
f x 293,500 × 30 = 2,205
f = 2,205/(293,500 x 30)
f = 0.0248%
If spread = 0 in 46 days
f x 293,500 × 46 = 2,205
f = 2,205/(293,500 x 46)
f = 0.0163%
