The real product

Log a trade, watch the buffer move

A losing MNQ trade is logged on a sample 50K evaluation: the trailing drawdown buffer drops from $1,780 to $1,340 and today's loss room from $1,000 to $560, on the spot.

Values come from trades already in Fillbook; fills your broker hasn't synced yet aren't included.

Trailing drawdown buffer:
how far the account can still fall before it breaches the firm's trailing drawdown
Today's loss room:
how much more you can lose today before hitting the daily loss limit

The result: 2 contracts bought at 21,000 and sold at 20,890 is a 110-point loss, about $440 (110 points × $2 per point × 2 contracts). Both readouts drop by that amount: the trailing drawdown buffer from $1,780 to $1,340, and today's loss room from $1,000 to $560.

What Fillbook does

Built around your funded account

Understand your account risk

Set each account's drawdown mode, daily loss limit and profit target, then see the buffer to your floor and today's loss room from the trades in Fillbook.

  • Presets for common prop firms; every value editable
  • Warns you before a limit; it can't block trades at your broker
  • Payout readiness scan for news blackout, overnight holding and payout buffer, from the settings you enter (Core)

Find what helps and hurts your trading

Break results down by setup, session and time of day, and see behavior flags such as revenge trading and overtrading, detected by rules from your trade history.

  • Results in dollars and R-multiples
  • Describes your past trades; it doesn't predict future results
  • Exit efficiency from MFE/MAE data (Core) and a review queue for trades you have not reviewed

Prepare for your next session

The Daily Brief recaps your last session, what the account has left and your strongest trading window, so you start the next session with a focus.

  • Journal notes, playbooks and a written trading plan
  • Plan adherence checked against your actual trades
  • Evaluation expected-value card using firms’ published reset fees where we have read them (Core)

Set up in three steps

  1. Connect or import

  2. Configure account rules

    Pick a firm preset or enter your drawdown and daily loss limits.

  3. Review your trading and buffer

    See what's working and how much room each account has left.

Share a view-only link with a mentor or coach on any paid plan (a trial does not count).
