See the approach work through a decision
Fictional inputs illustrate the research process, from starting assumptions to a decision.
Starting assumptions. Fictional Harbor Devices closes at $40 and trades at $44 after an earnings release, a 10% gap. After-hours volume is 120,000 shares versus average daily volume of 500,000 shares.
The volume ratio is 24%, above this template’s 20% threshold. A later $43 quote remains above the prior session high of $41. But a $42 bid and $43 ask leave a $1 spread. Read the actual release and guidance before deciding that the gap reflects an earnings surprise.
What to check next. A qualifying gap is a watchlist candidate, not an instruction to chase the ask. Recheck liquidity and the next opening range. Missing consensus estimates leave the double-beat criterion unresolved.
Setup criteria to review
- 1.EPS and revenue double-beat with positive guidance revisions
- 2.After-hours volume > 20% of 30-day average daily volume
- 3.Pre-market gap holding above prior session high
Exit & Risk Management
- 1.First 30-minute opening range breakdown
- 2.Target reached at average true range extension
- 3.Session-end market close exit
Research this in BrokerBridge
- Give Chat the earnings release, its publication time and the supplied expectations. Ask for a comparison and say: "Do not place, approve, or change any order."
- Separate regular-session prices from extended-hours quotes. Verify the spread and volume against the same session definitions before drafting an entry rule.
- Review the next-session plan and its destination before granting any trading authority. A scanner result alone is not a submitted order or a fill.
An explicit buy, sell or close-now request in Chat can authorize action without another approval click. Live permission can remain valid for later requests in the same chat and destination. Use the research wording above and read the Chat permissions lesson before requesting a trade.
