High win rate but the account isn't growing? Win rate vs avg win/loss from tastytrade
If you sell premium you probably know your win rate. 80%, 90%, whatever it is. But a lot of people with a high win rate look at their account and it just isn't growing. A few big losers wipe out a pile of small winners, and the win rate never shows it.
Win rate on its own can't tell you whether you're making money. You need it next to your average win and average loss. If your average loss is twice your average win, you need to win about 67% of the time just to break even, before fees. At three times, it's 75%. So a 75% win rate can be completely flat.
Tastytrade doesn't show win rate or average win/loss anywhere. All three are answerable, but you can't just ask Claude or ChatGPT to figure it out. I learned that the hard way. Splits and other corporate actions throw off the cost basis, rolls are hard to align, and expirations and assignments come through as separate entries. Get any of those wrong and the numbers you get back look better or worse than they really are. Getting that right is most of why OptionsInsights took as long as it did to build.
Has anyone else checked their win rate against their break-even? How far apart were they?
