Ask anyone who has failed a prop firm evaluation how it happened and the answer is rarely "my strategy stopped working". It is a Tuesday afternoon, two losses in, one more trade to get it back, and a daily loss limit that was breached by forty dollars. The edge was fine. The rules were not in front of them. A trading journal built for prop firm trading has one extra job on top of the usual statistics: keep the rules in view, and say something before a trade breaks one.

The three rules every challenge has

The names differ between firms, the structure does not.

Daily loss limit. The most you may lose in one trading day, usually 4% to 5% of the starting balance, sometimes measured from the previous day's closing balance or equity. On a $100,000 account that is $4,000 to $5,000. Breach it once and the account is gone, regardless of what happened the week before.

Maximum drawdown. The most the account may fall overall, typically 8% to 12%. It comes in two flavours. A static drawdown is measured from the starting balance: the floor is fixed at, say, $90,000. A trailing drawdown moves up with your high-water mark: if the account reaches $103,400, a 10% trailing limit lifts the floor to $93,060, and it never comes back down. Trailing rules are the ones that catch people, because the floor rises on your best day.

Profit target. What you must reach to pass, usually 8% to 10% for the first phase and 5% for the second. Many firms add a minimum number of trading days and a consistency rule (no single day may be more than a set share of total profit).

Why the journal has to know the rules

Your trading platform shows your balance. It does not show "how much of today's loss limit is left" or "how far above the trailing floor am I". Those are the two numbers that matter at the moment of decision, and doing the subtraction in your head after two losses is exactly when you get it wrong.

A concrete case. $100,000 account, 5% daily limit, you are down $3,800 on the day. The next setup calls for 1% risk, $1,000. On paper that leaves $200 of room. With spread, slippage and a fee, a full stop-out lands at $4,850 or $5,050. One of those numbers ends the account. A journal that knows the rule can put the warning on the trade form before the order is placed: this risk is more than what is left of today's limit.

Track peak-to-trough, not start-to-now

The common journaling mistake is to measure drawdown from the starting balance because that is the number you remember. With a trailing rule the relevant distance is from the highest balance the account has reached. The journal should therefore store the equity high-water mark per account and show the gap to the floor, in money and as a percent of the allowance used.

The demo account in SetupBook has a $50,000 prop account sitting $2,100 under its peak with a $2,500 allowance. The card shows 84% of the drawdown used and an orange warning; at 100% it turns red and reads "Limit hit". That is the display you want: not the balance, the distance to the cliff.

The 3 pm problem

Rules are broken late in the session, after losses, when the plan has been replaced by the need to get back to zero. The journal can help in three ways:

  • Break results down by session and by hour. Most traders discover that one slice of the day produces the losses and the rule breaches. Once it is a number, stopping at that hour is a decision instead of a feeling.
  • Put the rule in the pre-trade checklist. "Fewer than two losses today" and "risk below what is left of the daily limit" as checkbox items, ticked before the entry. A checklist that must be ticked is a pause, and a pause is often enough.
  • Count clean streaks. Days without a tagged mistake and without a rule breach, as a streak on the dashboard. For an evaluation, a long clean streak is worth more than a big day.

Keep the evaluation apart from everything else

Run the challenge in its own account inside the journal, with its own starting balance, its own break-even threshold and its own three limits. Do not mix it with a personal live account or a paper account: the limits, the currency and the psychology are different. A journal with multiple accounts should also only combine accounts in the same currency when it shows "all accounts"; adding a €5,000 account to a $100,000 one produces a number that means nothing.

What to send the firm, or your mentor

Some firms ask for a trading plan and a record; most mentors ask for a weekly summary. A one-page weekly report with net result, R, win rate, best and worst day, the mistakes that cost money and your own written review is enough, and it is far more credible than a screenshot of the platform's balance. A single trade can be shared as a read-only card when you want feedback on one decision rather than the week.

Setting it up in SetupBook

Create an account with the type Prop, enter the starting balance and the three rules: daily loss, maximum drawdown, profit target. From then on the dashboard shows a prop-limits card with the three bars and what is left of each; the trade form warns when the risk you are about to take is more than what is left of today's loss limit; and at 80% of a limit, and again when it is hit, the app says so once. The weekly report is a PNG you can download and send. The accounts section of the user guide walks through it with the demo's FTMO and Apex accounts, and a free account has no limit on how many prop accounts you track.
