Each result links to the full page: the rule we tested, the baseline, every trade and the worst loss.
How it works
Most 0DTE claims compare a rule with nothing. We compare it with the same trade without the rule, on the same days, and a gap that chance could explain counts as a tie.
- Step 1
Paste the claim
In plain English. We turn it into a rule you can read and edit: the strikes, the entry time, the target, the stop and the days.
- Step 2
We test it fairly
The rule runs minute by minute on real SPX option prices. The baseline is the same trade without the special part.
- Step 3
You get a plain verdict
Holds up, Tie or Does not hold up, with the average, the win rate and the worst loss. Private until you share it.
Tools at launch
Every number on every page comes from the backtest engine, and code checks it before you see it.
Claim Checker

Copilot
Ask in plain English. It runs the tools, quotes only their numbers and says so when it can't answer.
