    What is 0 DTE?

    SPY short put 0 DTE? it need to have at lest 1 day (1 DTE) to sell it…

    also what do you do, when it finish in the money? (you close with a loss?)

      0 DTE positions are same-day expiration. For example, opening a position Wednesday morning or afternoon with a Wednesday expiration.

      ITM positions that are held till expiration are “bought back” at the closing price (this methodology is the same whether the study is 0 DTE or 45 DTE). Trade P/L and Win/Loss status is calculated after factoring in initial premium received and commission costs.

    If 10D is the greatest risk/return…then why do you recommend 5D in your Trading Options Efficiently posts?

    Thanks so much for your posts, they’re amazing! Best I’ve found on the inter web.

      That’s because this is a completely different trade than what’s used in the Trading Options Efficiently mini series.

      The mini series focuses on a 45 DTE trade. This is on a 0 DTE trade that also experiences materially more timing luck due to the non-100% time-in-market exposure.

      You’re welcome! Appreciate the positive feedback!

    Firstly, your website and data look fantastic, thank you. It is really great reading.
    I have a question on ‘D’ in the above, you state that the 10D @ 50D is best risk-adjusted reward, would you mind expanding on this, do you mean the delta? and if so, what does 10 delta at 50 delta mean? I haven’t seen any other reference to ‘D’ other than talking of delta and I think I have got confused!

    Thank you in advance for your input, really am finding your research very insightful,

      Thanks for visiting Tintintrading! Glad to hear the info is helpful.

      Yes, the “D” is shorthand for “delta.” The “10D @ 50D” is a typo – good catch! It should read “10D @ 50% Max Profit or Expiration” I have corrected it 🙂
