trade evolved

Explore markets. Test an investing idea.

An ecosystem is a market. A species is an investing strategy following explicit rules. Explore either, then replay an idea through market history. Paper simulation only.

Access and pricing

Explore freely. Make it your own.

Explore the US large cap 100 daily field and published species examples without an account. Replay history, inspect holdings, and read their Results.

A free account lets you create and save personal species in the app. Field Pass increases capacity; it is not required to explore the public collection.

Free account

Free covers the US large cap 100 over the last 12 months. It gives 1 species and 1 variant of it, unlimited runs, and 5 compiles a day (50 a month).

Field Pass

$4.99 a month, or $39.99 a year

Field Pass pricing is pre-launch.

Field Pass adds the full history, every other market, variation and mating, Form and Scratch, and the sealed test. It removes the cap on species and variants. It gives 30 compiles a day (200 a month).

A compile turns a description into proposed rules.

What the allowances cover
Species
Saved strategies, each with its own rules.
Runs
Replays of those rules through a chosen historical period.
History
How far back a run can start. Free covers the last 12 months.
Compiles
Requests to turn a description into rules, including a revised description or a new retry. The daily allowance resets at midnight Eastern time. The monthly allowance resets on the first of the month, Eastern time.
How compile usage is counted

A request reserves a compile. If the service returns no usable answer, that allowance is refunded. A returned rules proposal still counts if it cannot be expressed or validated, or if you choose not to run it.

Simulation, data and limitations

The ecosystem describes historical data. It does not predict prices, rank stocks or suggest a trade. This is not investment advice. Nothing here routes to an order.

Prices and market values are from Financial Modeling Prep. Read the data sources and corrections.

WHY I BUILT TROPHIK

An ecologist's question about markets

Ecology and programming led me to Trophik's central idea: imagine investing strategies as species and the market as their environment.
