During a prop firm challenge, a trading journal must track three things a regular journal ignores: the real margin between you and the drawdown floor, the daily loss still available, and compliance with the challenge's own rules. These numbers change every day. Writing them down each morning, before the first trade, prevents most "surprise" fails.
You finished week one of the challenge at +3.2%. You know how much you made. But do you know, this morning, how much you can lose before being failed? If your drawdown trails, the answer is neither 6% nor 10%. It depends on your high, how it is measured and when your prop firm's day ends. Many traders find out the day the account closes.
This article names and recommends no prop firm.
Why is a challenge journal different?
Because in a challenge, you are not judged only on results, but on rules that can fail you before your method has time to play out.
| Regular journal | Challenge journal |
|---|---|
| Result of each trade | Result and margin left after each trade |
| Risk as % of capital | Risk as % of today's margin |
| Personal rules | Personal rules and challenge rules |
| Weekly review | Daily check before the session, weekly review |
| Goal: improve | Goal: pass without touching the floor, then stay funded |
The most common loss rules, and how a trailing drawdown can fail an account at −2.1% from the start, are covered in daily loss or trailing drawdown.
What to write down each morning before the first trade?
Four numbers, two minutes:
- Start-of-day balance (or equity, depending on your rules).
- Current floor of the max drawdown. If it trails, recalculate it from the high your prop firm uses.
- Today's margin: balance − floor.
- Daily loss available: today's limit, on its own base.
Then one decision: today's maximum risk per trade, based on the smaller of the two margins. Example: with $3,000 of margin and $5,000 of daily loss available, the $3,000 margin rules. To absorb a streak of 8 losses, risk per trade stays under 3,000 ÷ 8 ≈ $375.
How many losses in a row to plan for depends on your win rate. Losing streaks give the orders of magnitude.
The daily sheet to copy
| Field | Example (day 6 of a challenge) |
|---|---|
| Date | Tuesday, November 3 |
| Start-of-day balance | $103,200 |
| Recorded high | $104,000 |
| Floor (6% trailing) | $98,000 |
| Today's margin | $5,200 |
| Daily loss available (5%) | $5,160 |
| Max risk per trade (margin ÷ 8) | $650 |
| Max trades today | 3 |
| Restricted or avoided releases | 8:30 ET (example) |
| Session end time | 11:30 ET |
For each trade, on top of the usual fields (setup, entry, stop, result in R): plan respected yes or no, margin after the trade, and emotion at entry in one word.
These figures are examples. Replace them with your challenge's exact rules, read from the rulebook in force.

Which challenge rules to track on top of yours?
The ones that fail you without a big loss, and are therefore easy to forget:
- Restricted news releases. Some prop firms forbid opening or holding positions around certain releases.
- Minimum trading days. Hitting the target too early sometimes validates nothing.
- Consistency rules. Some require that no single day accounts for more than a given share of total profit.
- Overnight and weekend holding. Allowed or not, depending on the account type.
- Allowed instruments and maximum size.
Add each one as a rule to tick. The day you break it, you see it before the prop firm does.
What to track each week?
| Metric | Why |
|---|---|
| Share of "plan respected" trades | Discipline drops before results do |
| Average risk per trade, as % of margin | Spots a size that climbs as margin shrinks |
| Trades per day | Overtrading often follows a good week |
| Result of out-of-plan trades | Measures what indiscipline costs |
| End-of-week margin | The only gauge that matters for a fail |
What changes once you are funded?
Rules often loosen (no more profit target), and that is exactly the danger. Many funded traders drift: more trades, bigger size, less selective setups. Your challenge journal becomes the baseline. Each week on the funded account, compare trades per week, average risk, share of "plan respected" trades and setups used. A clear gap on any of them is a signal before the results confirm it. The prop firm challenge article covers this drift and the payout trap.
The limits of this method
- Every prop firm has its own rules. Adapt the sheet to your rulebook, reread at each new challenge.
- Your journal does not replace the prop firm's dashboard. If they differ, the prop firm's calculation counts. The journal is for anticipating, not disputing.
- The sheet takes time. Two minutes in the morning, thirty seconds per trade.
This content is educational and is not investment advice. No prop firm is recommended. Trading involves a risk of capital loss.
Keeping your challenge journal on Trade Stack
On Trade Stack, each challenge rule becomes a Rule in your journal. In each Deep Review (Funded plan), you mark whether it was respected, and the respect rate is calculated rule by rule. The Discipline section of the Overview compares your "plan respected" trades with the others and puts a number on the cost of indiscipline. With multi-account on the Funded plan, each challenge and funded account keeps its own history.

Key takeaways
- In a challenge, your journal tracks today's margin and the daily loss available, not just trades.
- Every morning: balance, floor, margin, daily loss available, then max risk per trade.
- Challenge rules (news, minimum days, consistency) get ticked like your own rules.
- Every week: discipline, average risk, frequency, cost of out-of-plan trades, margin left.
- Once funded, the challenge journal is your baseline for spotting drift.
Method: sheet and figures built for illustration ($100,000 account, 5% daily loss, 6% trailing drawdown). 103,200 × 5% = 5,160; 103,200 − 98,000 = 5,200; 5,200 ÷ 8 = 650; 3,000 ÷ 8 = 375. No specific prop firm.
