Periodic Gains is a research lab for market rules. Write ideas in plain settings, run them in a simulator, and get a clear explanation of every decision the rules made.

What you can do
Built for curiosity and learning, not tips or signals.
Build rules without code
Start from an annotated template or a blank form. Every setting has a plain-English ⓘ explanation, with Simple and Advanced views.
Simulate in real time
Watch your rules run against live market data in a simulated account. No real money is involved.
Test on history
The Incubator replays your rules over past market data so you can study how they would have behaved, including where they break down.
See why, not just what
"Explain this trade" walks through which rule fired and why, so you learn the logic instead of guessing.
AI research assistant
Describe an idea in your own words and the AI drafts the settings for you to review and test.
Learn with others
A moderated community where people share setups, ask questions and compare notes.
How it works
Most people run their first simulation in about 10 minutes.
Create an account
Free 14-day trial with full access. No card needed.
Connect free market data
Link a free Alpaca paper account so the simulator has live prices. Our Getting Started guide walks you through it.
Pick a template
Choose a starter template. Each one is labeled unproven, because the point is to test it, not trust it.
Observe and adjust
Review results, read the explanations, change a setting and run it again.
Who it's for
- Learners who want to understand indicators and rules by watching them work, not by reading about them.
- Tinkerers who have ideas and want a sandbox to test them safely.
- Script writers moving from chart scripts to a structured, testable rule set.
