This page explains how automated 0DTE options alerts are produced and what they can and cannot tell you. It describes software behaviour and market mechanics. It is not investment advice and does not recommend any trade.
What a 0DTE options alert is
A 0DTE options alert is a notification generated by monitoring software when live market conditions match a set of pre-configured rules, concerning an option contract that expires in the current session.
The important word is pre-configured. An automated alert is not a judgment about your situation. The rules were written before the session began, they are applied identically to every subscriber, and the software has no knowledge of your account, your risk tolerance, or anything else about you. An alert is a statement that conditions matched a pattern — nothing more.
What a scanner evaluates before sending one
Implementations differ, but a rules-based same-day scanner generally reads some combination of the following:
Price movement. Direction and magnitude of the current move in the underlying, usually measured against a recent baseline rather than in absolute terms.
Relative volume. Current volume compared with what is typical for that instrument at that time of day. Raw volume is close to meaningless without the time-of-day comparison, since volume is naturally concentrated around the open and the close.
Trend. Whether shorter-horizon movement agrees with longer-horizon movement, which is what separates a directional move from noise inside a range.
Broader market context. Whether the wider market is trending or chopping. A signal that is meaningful in a directional tape is frequently noise in a range-bound one, which is why context is applied as a gate rather than as one input among many.
Option candidate selection. Which same-day contract corresponds to the observation — strike and expiration — and whether it is actually tradeable.
Liquidity. Bid-ask spread and quote quality on that specific contract. A contract with a wide spread can be effectively untradeable at the displayed midpoint regardless of how well the underlying observation scored.
What a well-formed alert contains
An alert is more useful when it shows its inputs rather than only its conclusion. A reasonably complete one identifies:
- The ticker.
- The observed direction — bullish or bearish, based on what the scanner measured.
- The specific option contract observed.
- A bid, ask, and midpoint snapshot.
- The timestamp of that quote.
- A setup score, where the software produces one.
What a setup score is not
Scanners often attach a numeric score to an alert. It is worth being precise about what such a number represents.
A setup score is a ranking of how well conditions matched the configured rules. It is not a probability of profit, not a confidence interval, and not a prediction. A score of 90 does not mean a 90% chance of anything. It means the observation matched the rules more completely than one scoring 60.
Any service presenting a score as a probability of profit is making a claim that requires substantiation.
The limits worth understanding
Quotes can be stale. A quote snapshot describes a moment that has already passed. By the time an alert is delivered and read, the market may have moved.
An observed price may never be executable. A displayed midpoint is not an offer. Spread, depth, and speed of movement all determine what actually fills.
Delivery is not guaranteed. Alerts depend on market data providers, internet connectivity, and a messaging platform. They can be late, duplicated, incomplete, or missing entirely.
Alert frequency is not guaranteed. A rules-based scanner sends alerts when conditions match. On a session where nothing matches, a well-configured scanner sends nothing. Zero alerts on a choppy day is the filter working, not the filter failing — but it does mean volume is unpredictable.
Costs are certain; outcomes are not. Spread, slippage, commissions, and fees are paid on every entry and exit, and they consume a larger proportional share of a small, fast-moving same-day premium than of a longer-dated position.
The instrument underneath
0DTE contracts expire at the end of the session in which they trade. Extrinsic value converges toward zero as the session progresses, and a contract that is out of the money at expiration is worth nothing. Losing 100% of the premium paid is a routine outcome, not an edge case. See what 0DTE means for the full mechanics.
How OptionsNow handles this
OptionsNow monitors the session, applies its configured qualification rules, and posts alerts to a private Telegram channel. Each alert identifies the ticker, observed direction, observed contract, a bid/ask/midpoint snapshot, the quote time, and a setup score when available. Follow-up messages note when a monitored setup changes.
It does not connect to a brokerage, cannot place or manage trades, does not produce personalized recommendations, and does not consider any subscriber's circumstances. No performance is promised or implied, and no alert guarantees a profitable or available trade.
