Everyone argues about whether cheap far-out options are dumb. Well…

    If losers go to zero and you hold winners to target, the hit rate you need just to break even is set by the payoff:

    Winner pays Break-even hit rate
    3x 33.3%
    5x 20.0%
    10x 10.0%
    20x 5.0%

    That's to go flat. Not to make money.

    Now the part that actually matters. Losers go to zero is a choice, obviously…. Cut them at −50% instead:

    Winner pays Hold to zero Cut at −50%
    3x 33.3% 20.0%
    5x 20.0% 11.1%
    10x 10.0% 5.3%
    20x 5.0% 2.6%

    Cutting at half roughly halves the hit rate you need. That's a bigger edge than any amount of better picking, and it's free. The problem is a 3-cent contract doesn't feel worth managing, so it gets held to expiry, and your real break-even is the left column instead of the right one.

    Then the spread. On a 0.45/0.55 quote you're down 20% at fill. On 0.01/0.02 you're down 50% before you've done anything — your stop got hit the moment you bought. That's why this stuff paper-trades great and trades terribly.

    So: 10x needs 10% holding to zero, ~5% if you cut, back to ~7% after a normal spread, and sub-10-cent contracts are basically unplayable.

    Lotto tickets aren't automatically losers. But nearly all the edge is in the exit, not the entry.

    Anyone actually track their hit rate on sub-$1 contracts separately? I'd bet it's a lot worse than your overall win rate is hiding.

    Cheap options aren't the problem. Holding them to zero is. Here's the math.

      Nh, first you have to figure out how many -50% go on to be big winners

      knee jerk simplistic stop losses are, knee jerk and simplistic
