Tools for watching and studying 0DTE (same-day expiration)
Watch or study same-day expirations as research — not a ranking of the best 0DTE platform.
0DTE (zero days to expiration) software helps you watch or study contracts that expire the same day. Typical pieces include a same-day expiration filter on a flow tape, a short-dated backtest, or a scanner you can set to today’s expiry.
This is research and watch software. It is not a broker race, not an execution-speed ranking, and not a commissions comparison. Same-day options can expire worthless in hours. We do not claim that watching 0DTE prints or replaying short-dated rules improves returns.
Use this job if you want to look at same-day expirations before you send an order somewhere else. Do not use it as a “best 0DTE platform” list.
A listing is a job match, not a ranking. We only tag a tool here when the existing review or that product’s official pages already describe same-day / 0DTE watching or study. Flow products that merely filter by expiration, without naming 0DTE, stay untagged.
Canadian readers: public 0DTE coverage is typically US-listed / OPRA (index and ETF weeklies are the usual examples). Canadian-listed same-day coverage is unverified for each tool unless a review says otherwise.
