  1. Great article! Not often do I find a simple explanation for ITM and OTM. What I was most fascinated about though was the P50, I had never heard of that?

    P50 may be more toward my trading style since I do like having more winning than losing trades for psychological reasons. I find that more frequent, smaller wins allows me to better abide my trading rules and stick to the plan.

    Although, I’ve had to re-adjust a lot of my back testing to suit my trading style with more wins and less losses, I’m more comfortable in my own trading skin.

    Tastyworks is a platform I’d have to check out for this reason, do you recommend them for anything else other than P50?

    Cheers Rohan

    1. Thanks for the comment Rohan! 

      I absolutely recommend tastyworks for something else than the simple P50 feature. The P50 feature is just one of many examples of their great platform. I use tastyworks for all my trading because they are so great.

      If you want to learn more about tastyworks’ features and why I recommend them, make sure to read my tastyworks review.

  2. Hi Louis, Thanks for this detailed and thorough article. I feel I have a much better understanding of option trading probabilities. I also appreciate the section on the Probability of Touch, which is a new concept for me.

    One thing I am learning more about is trading options around earnings. I am curious if you can speak to how earnings seasons can affect the ITM and OTM probabilities for stocks. Could you look at the probabilities, for example, and get a sense of the direction that a stock cold move prior to earnings?

    Thanks for any insights you can provide!

    1. Thanks for the comment Laura.

      As you know from my article about trading options on earnings, implied volatility (IV) usually increases before an earnings announcement. An increase in IV means that the market expects a big upcoming move. This will also impact the probability of ITM/OTM. If a big move is expected, the probability that an option will expire OTM decreases and simultaneously the probability that an option will expire ITM increases.

      Hopefully, this makes sense to you. If a price will likely move a lot soon, it makes sense that options have a higher probability of expiring ITM than if no big move is expected. 

      When setting up an earnings trades, you could definitely use these different probabilities. Ideally, you should set up a strategy that hasn’t a very low probability of profit. 

      I don’t really know a way to use probabilities to predict how a stock will react to earnings though.

      I hope this could help you out.

      1. Hello Louis,

        I’ve lost tens of thousands of dollars just buy buying calls or puts right before earnings and either I chose the wrong strike or there was no up move at all

        I always thought it’s best to sell premiums via credit spreads during earnings because the IV is much higher than the underlying’s HV

        Please give me your thoughts on this. Thanks.

        1. Thanks for your comment. It is correct that IV usually rises leading up to earnings. On earnings, however, IV tends to drop quite a lot which is great for overall short premium strategies. Credit spreads are a way of trying to profit from this. However, there are other strategies that can profit much more from this IV drop than credit spreads. Furthermore, you take a directional bet with a credit spread which can be quite risky on earnings as prices often tend to move a lot after an earnings announcement. So when you get caught on the wrong side, the IV crush won’t be enough to compensate the losses incurred through the price move of the underlying asset.
          I have an article on how to trade options on earnings. In it, I go over this IV drop and suitable strategies much more thoroughly. Just note that this strategy can be quite risky.
          Hopefully, this helps.

    On Sky View Trading recommend we use 30% Prob ITM that equal to 60% Prob of Touch, right? That gives good Credit but may need adjustment if the price against us. So I get confused which one to choose 30% or 42% Prob ITM? As 84% POP sounds good to trade. Thanks

    1. Hi Harry,
      If a strike has a 30% probability of ITM, it should have a probability of touch of about 60%. So yes, you are right.
      As to which probability is best, I can’t give you a concrete answer. It really depends on the situation and your personal preferences. In my opinion, neither 30% or 42% is better. It just really depends. But as long as you collect enough credit and have a decent probability of success, you can’t really go wrong.
