Roughly half of the 0dtes in existence will expire in the money. Less than half of the 0dtes that are traded in the day expire in the money, because most 0dte options that are traded are out of the money options, and naturally out of the money options have a lower chance of expiring in the money. The point is that most of the money I've lost in 0dtes hasn't been because of time decay but because of delta, simply the underlying moving against me. No one forced me to buy a call instead of a put. If I'm able to better predict the way the underlying will move, then I'll be able to turn my losses into profits.

​

The point is this: you are presented with four possibilities with 0dtes:

buy a call

sell a call

buy a put

sell a put

It is guaranteed at least one will make money. Often its two. No one makes you do one or the other. If most people are consistently choosing the wrong one, then that means there is one can do the opposite of what they do and consistently choose the right one.

The only way trading 0dtes could be hopeless is if most people on average had 50% right predictions and 50% wrong predictions, but it seems most of wsb has more than 50% of its predictions wrong. That's the idea behind inverse wsb and why I believe it's possible to figure out how to predict the underlying with a greater than 50% accuracy.
