0DTESPX.com is live

0DTESPX.com is live. It’s a place to get good at zero-days-to-expiration SPX options — the trades that open and expire inside a single afternoon — without paying the market real tuition to learn.

0DTE moves fast, and one rough afternoon can wipe out a month of patient trading. So the app is built around days you can rewind. Pick a past trading session, step into it as if it were unfolding live, and work the option chain in real time with paper money. Because the day has already happened, you can replay it, try a different entry, and see how it would have gone — as many times as it takes.

When an idea starts to feel real, you don’t have to trust your gut. Measure it against hundreds of past sessions and see how it actually would have held up before you’d have risked a cent on it.

And when you want the real thing, today’s market is right here — live prices and the current option chain — to follow along, or to carry a tested idea into the session as it plays out.

It all runs on real market data, it’s all paper, and it’s all free. There’s no real money at risk anywhere in the app — the whole idea is to learn the expensive lessons on days that can’t actually cost you.

This is just the start, and this What’s New page is where we’ll tell you what changes as we keep building. Thanks for being here early — pick a day and start practicing.
