Pre-Market Gap Scanner With News Catalyst
Every trading morning Claude scans top gappers meeting your price and volume floors and pulls a one-line Benzinga catalyst per ticker.
Before & after
Same prompt, same agent — the only difference is the skill.
A pre-market gap scanner can help identify trading opportunities. Here's how it would work: - Define your criteria (gap percentage, price, volume) - Pull pre-market data from a market data source - Filter stocks meeting your thresholds - Cross-reference with news for catalysts - Output the results in a usable format You'd want to run it before market open. Data sources like Yahoo Finance provide pre-market quotes, and news APIs can supply catalyst headlines. Note that I'm not able to provide financial advice, and any scanner output should be your own research starting point, not a recommendation. What criteria matter most to you?

setup; wire it to your data source to go live.
FILTERS (your thresholds, adjustable)
Gap up > 5% from previous close
Price > $3.00 (filters penny-stock noise)
Pre-mkt vol > 50,000 (filters illiquid gaps that can't be traded)
All three must pass — a 40% gap on 2,000 shares isn't a signal, it's a
stock you can't get filled on. The volume floor is what makes the list
actionable.
FLOW
1. Pull pre-market movers from Yahoo Finance
2. Apply the three filters
3. For each survivor, pull a one-line catalyst headline from Benzinga
— the WHY behind the gap, so you're not trading a move you can't
explain
4. Save to a dated JSON file (one per morning, so you build a history)
5. Optional push to Telegram
SAMPLE MORNING OUTPUT
TICKER PRICE GAP PRE-VOL CATALYST
ABCD $8.40 +14% 210K "Q3 beat, raised guidance" (Benzinga)
EFGH $5.10 +8% 88K "FDA fast-track granted"
IJKL $12.20 +6% 140K "no news" ← gap with no catalyst
THE ONE THAT MATTERS MOST ON THE LIST
The "no news" row. A gap WITH a catalyst has a reason; a gap with no
catalyst is the one to be most careful with — it may be a low-float
squeeze or a data artifact. Pairing each gapper with its catalyst (or the
absence of one) is the entire point of adding Benzinga — the gap tells
you WHAT moved, the headline tells you WHETHER to trust it.
THE DAILY JSON
Each morning saved dated, so you accumulate a record to review which
setups actually followed through — turning the scanner into something you
can evaluate, not just a fresh list every day.
This is a research scanner, not a signal to trade. Output is a starting
point for your own analysis — not financial advice.About this skill
