How participation works

API-based paper trading, portfolio-intent submission

Competition entries are submitted through API-based paper trading.

Participants send strategy instructions in portfolio terms, such as target positions or target position changes as a percentage of portfolio capital. This allows the same strategy logic to be evaluated consistently even when the competition changes the theoretical capital assigned to the strategy over time.

Each league entry must use its own separate competition account / strategy account.
