Before you join. After you submit.

Historical backtesting accepts Python strategies for a fixed 2005–2022 backtest window, ranked by Sharpe, CAGR and max drawdown in that order. Live paper trading accepts orders through the API and tracks a paper account from the time you join, ranking by cumulative return and comparing with QQQ over the same period. The tracks have separate participation, records and rankings; old backtest results do not transfer to the paper leaderboard.

Both leaderboards are public. Participation still requires registration, email verification and waitlist approval. The paper leaderboard publishes strategy names and performance summaries only. Email, positions, orders and fill details are private to the owner and administrators. Do not include emails, real names or other private information in strategy names.

No. Both tracks start with USD 100,000 in simulated capital. Live paper trading uses fills calculated by the platform from market data, not actual QC orders or exchange executions. It does not connect to real-money accounts or guarantee real execution performance.

Visit registration and enter your email. Complete the human verification to receive a verification link. After verifying your email and setting a password, you enter the waitlist. A superuser must approve you before you can sign in and participate.

Visit password recovery and complete human verification to send a reset link to your verified email. Resetting your password invalidates old browser sessions, so sign in again. Existing API tokens are retained; scripts do not need new tokens. If you suspect a token leak, sign in and revoke it on the API Token page. Do not share passwords or tokens in chat, GitHub or public logs. Repeated failed sign-ins may temporarily lock the account.

You can use the REST API for separate participant accounts. Each account must use its own tokens and records; do not share one identity to simulate different participants. In paper trading, each user has one account whose initial capital cannot be reset.

Submit main.py and metadata through the REST API. The website provides guidance, token management, submission history and the backtest leaderboard. View the backtest API guide .

Acceptance does not mean the backtest is complete. A run may still be waiting, executing or processing results. Use the server status in My submissions. Queue positions or completion times are not estimated without live queue information.

If you received a Run ID, query that run first. A client timeout does not stop the remote run. Ask an operator to check paused runs or uncertain remote states; do not force a rerun with repeated submissions.

The backtest API returns the existing run for an identical submission without creating another run. Modified submissions are subject to the backtest quota. Check the actual response to confirm the Run ID.

Backtest completion, available metrics and ranking eligibility are different conditions. An incomplete window, observed rule violation or unavailable metrics may exclude a run from current rankings. Check the run's feedback.

No. Raw evidence may not prove every behavior. The current historical backtest policy treats reliable counterexamples as violations and otherwise treats entries as compliant. This is not full technical verification of all behavior. Original statuses remain in the result JSON.

No. This is an internal beta and non-official evaluation, not a final award decision. Full backtest rules are in Historical backtest rules .

After signing in, open Paper account and enter a strategy name to create an account. Use an existing valid API token or visit API Token to create a new credential. New and existing tokens can trade by default, without a separate switch. Send buy/sell orders through the API; the website displays performance read-only. Registration still requires email verification and administrator approval. Disabled or waitlisted accounts and revoked or expired tokens remain blocked. Publicly available rules: Live paper-trading rules ; request examples available after sign-in: Trading API documentation ; documentation for both tracks: Documentation .

No. Live paper trading accepts integer-share market orders during regular trading hours only. Buys use ask + 5bp and sells use bid − 5bp. Commission is $0.005 per share with a $1 minimum per order. Settlement is immediate, making sale proceeds available at once. Trading is long-only, without overselling. Best bid/ask quotes cannot fully simulate large-order impact. Full execution, ranking and review policies are in the public Live paper-trading rules .

Orders wait for valid quotes received after acceptance and expire after 30 seconds if unfilled. Stale quotes, feed interruptions under review or unavailable valuations do not produce fabricated fills or ranks; the page shows the status clearly. No new orders fill when the market is closed. Query the original order first; do not blindly retry with a different request_key.

No. The 10-per-24-hour limit applies to historical backtest submissions; administrators can exempt individual accounts. Paper orders have separate limits: up to 30 new orders per account per minute, plus pending-order and subscription-capacity limits. Safe retries using the same request_key do not create another order.
