Market Shortlist

Stop searching. Know what's moving.

Periodic Gains automatically scores and ranks your watchlist universe every 30 seconds during market hours. The 🚀 rocket signal fires when all the conditions align — so you know exactly where to look.

📊
Score
Composite momentum score — gap, volume, MACD, ORB, and news all factored in
💪
Strength
Close rank 0–100 — where today's price sits vs the past 52 weeks. 80+ = near 52-week high
↑↑
Trend
Whether Strength is rising over consecutive 30-min snapshots — a confirmed momentum shift
⚡
Surge
Near the day's high with above-average volume — the stock is actively surging, not fading
🚀
Rocket Signal
Score ≥ 80 + surge + trend aligned. Synced to strategy entry conditions automatically every cycle
📉
Dive Signal
Within 2% of the day's low with above-average volume — confirmed bearish pressure for put strategies
Every column a trader checks — on one row
🔒
Today's Best, locked
Best Surge & Best Dive, Squeeze up & down and the Momentum Leaders — one clear pick each, locked before 10:00.
🏁
HOD / LOD count
How many new highs or lows a stock has made today, and when — the quickest read on who's leading.
📏
Opening range & prior day
Price vs the 5-minute opening range and yesterday's high/low — is it breaking out or stuck inside?
📐
Daily 9 EMA & streak
Which side of the daily 9 EMA a stock is on, and for how many days in a row.
🗜️
TTM Squeeze
Daily squeeze state — spot compression before it releases.
⚡
Relative volume
Pace-adjusted RVOL, so 10 AM volume is compared fairly with a full day.
🩳
Float & short interest
Small floats and heavy short interest — the fuel behind squeezes.
🧮
IV, expected move & spread
Implied volatility, the day's expected move and the option spread — know if the options are worth trading.
📅
Earnings timing
Before-open or after-close reports flagged right on the row, including beats and misses.
🌙
Swing & overnight scores
0–10 scores for holding overnight and for a big next-morning move.
🌊
Morning regime
Is this a trend morning or a fade morning? One chip tells you before you chase a gap.
📌
Pin your symbols
Pin up to 10 tickers to their own table so you never lose track of them.
✓ Bullish & bearish entry filtering
Require 🚀 rocket for calls or 📉 dive for puts — only enters when the shortlist confirms your direction
✓ Momentum exits
RSI Divergence / Convergence exits, HOD drop, rapid drop, and MACD cross — all configurable per strategy
✓ Live calibration
Strategy editor shows real-time shortlist values — set thresholds against actual data, not guesses

⚗️ The Litmus Test · New on every plan

Got a trading idea?
Find out in a minute.

Most trading ideas feel great until you check them. Describe yours the way you'd tell a friend, and the Litmus Test turns it into clear rules, runs it over years of real market history, and tells you in plain English whether it ever had an edge — before you spend a week building a strategy around it.

💬 You describe it
“Day trade: buy when the 5-minute RSI crosses above 70, sell when RSI reaches 85 or it drops 2%.”
🧩 It becomes rules you can click and change
⏱ 5-minute bars〽 RSI(14) crosses above 70 🕘 09:35–15:00 ET⭐ exit: RSI ≥ 85 or −2% stop 🗂 your watchlists
🧪 You get an honest answer
📋A verdict, a short “what happened” in plain English, every exit compared side by side, and one-click next experiments — “only above VWAP”, “only with the daily trend”, “try a 15-minute window”… Then, if it holds up, make it a Lab strategy in one click.
Illustration of the workflow — not a real result.
1
Describe it
Plain English, or pick from the menus: RSI, moving averages, MACD, gaps, VWAP, opening range, volume, trend filters and more.
2
Daily or intraday
Test swing ideas on years of daily bars, or day-trade ideas on 5-minute bars — with your own exit or ours.
3
A fair comparison
Every result is measured against the same trade taken on ordinary days, so a rising market can't make a bad idea look good.
4
No fooling yourself
Tuned on older data, checked on newer data it never saw. The more variations you try, the higher the bar — and a hidden final exam you can take once.
5
Make it a strategy
Turn a winning idea into a Lab strategy in one click — shares or options — and watch whether it trades like the test said.

🧫 The Incubator · Coming soon

Months of testing.
Done in minutes.

The Lab finds better entries and exits one market day at a time. The Incubator speeds that up: pick one strategy, replay it over months of real historical market data, and let it try hundreds of entry and exit variations to find what would have worked best — then confirm the winner live in the Lab.

1
Pick a strategy
Choose any of your strategies, a date range, and which settings it's allowed to change — stops, targets, trailing exits, time cutoffs, entry filters.
2
Replay history
Your strategy runs minute by minute through real historical stock and options data, using the same rules and the same honest fills (buy at the ask, sell at the bid) as the Lab.
3
Search the variations
Hundreds of entry and exit combinations are tested in the background while you keep working — no waiting weeks for the market to deliver a sample.
4
Keep only what holds up
Each variation is tuned on one period and scored on a later period it never saw. Results that depend on one or two lucky trades are flagged, not crowned.
5
Prove it in the Lab
Send the winner to a Lab forward test in one click and compare what the Incubator predicted with how it actually trades.

Included with Mad Scientist and Mad Scientist Annual (paid plans; not part of the free trial). Historical results are hypothetical — past performance doesn't guarantee future results.

Pricing

Simple, transparent pricing

Every new account starts with a 14-day full-access trial (all Mad Scientist features except the 🧫 Incubator, which is for paid Mad Scientist plans) — no card required. Simulated results are for research and education; not investment advice.

⚠ Risk Disclosure, Legal Disclaimer & Tools-Only Notice

Periodic Gains Is a Software Tool — Not a Financial Service.
Periodic Gains provides strategy simulation and automation tooling only. This platform does not provide financial advice, investment advice, trading advice, tax advice, or any other type of professional financial guidance. Nothing on this website, within the application, within AI-generated strategy configurations, or within the community constitutes a recommendation to buy, sell, or hold any security, option, or other financial instrument. Periodic Gains and its owners are not registered investment advisers, broker-dealers, commodity trading advisers, or financial planners, and are not affiliated with any regulatory body such as the SEC, FINRA, or the CFTC.

Risk of Loss.
Trading stocks, options, ETFs, and other financial instruments involves substantial risk of loss, including the possible loss of all capital invested. Markets can move rapidly and unpredictably. Automated systems can experience technical failures, connectivity outages, latency, order rejections, or erroneous executions. You should only trade with funds you can afford to lose entirely. If you are unsure whether trading is appropriate for your financial situation, consult a licensed financial professional before using this platform.

Simulated & Hypothetical Performance.
Periodic Gains is primarily a strategy simulator. All strategy results shown in the Lab are simulated / hypothetical and involve no real money. Simulated and hypothetical performance results have inherent limitations. Unlike an actual trading record, simulated results do not represent real trading and may under- or over-compensate for factors such as liquidity, market impact, slippage, order rejections, and the ability to withstand losses. Simulated fills are modeled — and modeled optimistically — and will differ from real executions. Because the trades were not actually executed, results may understate or overstate the impact of real market conditions. No representation is being made that any account will, or is likely to, achieve profits or losses similar to those shown. Past and simulated performance is not indicative of future results.

AI-Generated Strategies.
The AI Strategy Builder translates your described logic into a configuration file. It is a translation tool only — it does not suggest what to trade, when to trade, or how much risk to take. AI-generated output may contain errors, omissions, or logic that does not match your intent. It is your sole responsibility to review, verify, and test every strategy — including AI-generated ones — before deploying with real funds. We strongly recommend independent review by another AI tool, a qualified developer, or a licensed financial professional, and extended paper trading before going live.

Broker Proprietary Code & Platform Limitations.
Some broker platforms use proprietary scripting languages (e.g., ThinkScript, EasyLanguage) that cannot be fully replicated in an open API environment. Periodic Gains makes every effort to translate your strategy logic as accurately as possible, but certain indicators, order types, or conditions may be subject to limitations or require workarounds due to broker API restrictions. A list of known limitations is maintained within the platform and is available for your review at any time. Periodic Gains makes no guarantee that translated strategies will behave identically to their original broker-native form.

Community Content.
Strategies, parameters, and discussion shared by community members are user-generated content. They do not represent endorsements or recommendations by Periodic Gains. Past results shared by other users are not indicative of future performance for you or anyone else.

Your Responsibilities.
All strategy configurations, risk settings, position sizing, and trading decisions are defined entirely by you and executed mechanically according to your configuration. You are solely responsible for all trading outcomes, tax obligations, regulatory compliance, and any losses incurred. By creating an account you acknowledge you have read, understand, and agree to these disclosures in full.
