Paper Trader

Takes validated strategy parameters and simulates them forward as paper trades, tracking open positions, exit signals, and running P&L over a chosen window.

For research and education only. This is not investment advice; you run any real or paper trades yourself through your own brokerage or paper-trading account.

How to work through it

  1. Confirm the parameters and window, and restate the entry and exit rules.
  2. On each check, evaluate entries: e.g. buy when a name dips the threshold from its recent high, sized within the position limit.
  3. For each open position, check exits every interval: take-profit hit, stop-loss hit, or hold period expired.
  4. Track each fill, side, quantity, and price, and maintain running realized and unrealized P&L.
  5. Enforce risk limits such as position-size caps and any overnight-hold rules for small accounts.
  6. Report periodic trade updates and a final summary: total trades, wins/losses, total P&L, and open positions.
