Most stock scanners assume you already know a query language. This one doesn't. If you're new to scanning, describe a setup the way you'd say it out loud — "stocks near their 52-week high with rising volume" — and the AI assistant writes the scan condition for you. If you already know what you're doing, skip straight to the plain bracket-condition editor and write it yourself. Either way, the same one-click Run button takes it from idea to results.

Open AI Scan Builder and describe your setup in plain English, or pick one of the built-in example scans to start from.
Review the AI-generated (or hand-written) scan, then click Run — matches come back against the S&P 500, Nasdaq-100, Dow 30, or the full universe.
Save the scan you like, re-run it in one click whenever you want, or put it on a schedule so it runs itself.
Real syntax, no coding required
[Daily RSI(14) < 30] AND [Daily Close > SMA(200)]
[Weekly Close crosses_above EMA(50)] AND [universe = SP500]
[Fundamentals PE < 15] AND [Fundamentals ROE > 10]
You never have to type syntax like this by hand — this is what the Gen AI assistant produces from a plain-English description, shown here so you know exactly what you're running before you click Run.
Prefix any of these with Daily, Weekly, or Monthly (defaults to Daily) and combine with AND/OR/NOT — only these periods are precomputed nightly so a scan stays fast across the whole symbol universe, so a period outside the list (e.g. SMA(37)) is rejected rather than silently ignored.
SMA(period) / EMA(period) — moving averages of Close. SMA periods: 10, 20, 50, 100, 150, 200. EMA periods: 8, 13, 20, 21, 34, 50, 100, 200.
RSI(period) — Wilder's RSI, periods 5/9/14/21 (bare RSI defaults to 14).
ROC(period) — rate of change vs. N bars ago, periods 1/5/10/20/63/126/252 (bare ROC defaults to 1).
MACD, MACDSignal, MACDHistogram — standard 12/26/9 MACD.
Week52High / Week52Low — trailing 252-bar high/low, daily only.
Close, Volume, DollarVolume (Close × Volume, a liquidity filter) — raw values, no period.
StashConfluence — StashGamma's own 0–100 trend+momentum composite, blended with a fundamentals-quality score when available. Not a textbook indicator (no Bollinger Bands/ATR/Stochastic math involved) — our own blend, works on any timeframe.
Comparators: > < >= <= = !=, plus crosses_above / crosses_below for the prior-bar transition.
Yes. AI Scan Builder is on the free tier of a StashGamma account — no credit card, no trial countdown. Sign up, and it's ready to use.
No. It's built for novice and self-taught traders as much as coders: type what you're looking for in plain English ("stocks with RSI under 30 and price above the 200-day average") and the built-in Gen AI assistant writes the scan for you. If you prefer, you can also write conditions directly in a simple bracket syntax — no programming language involved either way.
A natural-language-to-scan translator: describe a setup in your own words and the assistant converts it into a working scan condition against the indicator engine (moving averages, RSI, MACD, rate of change, 52-week highs/lows, fundamentals, and StashGamma's own Confluence composite score) — you review and can edit the generated scan before running it.
Once a scan is built (by AI or by hand) or saved from a previous session, running it is a single "Run" click — it scans the S&P 500, Nasdaq-100, Dow 30, or the full symbol universe and returns matches immediately, no manual per-symbol lookups.
Yes. Save any scan by name, re-run it in one click any time, optionally put it on a recurring schedule, and pull up its run history to see what matched on previous days.
Technicals (SMA/EMA/RSI/MACD/ROC/52-week highs & lows), raw price and volume conditions, fundamentals (P/E, margins, growth, debt ratios, and more), and StashGamma's proprietary Confluence trend+momentum score — combined with AND / OR / NOT across Daily, Weekly, or Monthly timeframes.
Not literally — it isn't ChatGPT and isn't affiliated with OpenAI. But the idea people mean when they say that is right: describe a setup in plain English instead of learning a query syntax, and a purpose-built AI assistant turns it into a real scan (not a general-purpose chatbot).
