Turn a daily risk percentage into a dollar budget, subtract realized and open risk, reserve a safety cushion, and plan the day’s remaining trades.
STEP-BY-STEP
How to use this tool
- Enter the current balance and a personal daily risk percentage below any binding loss limit.
- Add realized losses already taken today. Do not offset them with unrealized or hoped-for profits.
- Add the full planned loss on open positions.
- Reserve a dollar cushion for fees, slippage, gaps or rule uncertainty.
- Enter the number of trades still permitted by your plan and proposed risk for each.
- Stop adding risk when the usable budget is exhausted, and verify firm-specific reset and loss calculations separately.
WORKED EXAMPLE
See the calculation in context
A $50,000 balance with a 2% daily budget creates $1,000. After a $100 reserve, $250 realized loss and $250 open risk, $400 remains. With two trades planned, the equal allowance is $200 per trade.
Calculation method
Daily budget = current balance × daily risk percentage. Usable budget = daily budget − safety reserve. Remaining budget = usable budget − realized losses − open-position risk. Equal per-trade allowance divides the remainder by planned trades.
AVOID THESE ERRORS
Common mistakes
- Using the entire prop-firm daily loss limit as a personal budget
- Subtracting unrealized profits from risk used
- Ignoring open-position risk
- Planning more trades after the budget is exhausted
- Omitting a cushion for fees and slippage
- Assuming the budget resets at local midnight
FREQUENTLY ASKED
Questions and answers
Should profits increase today’s risk budget?
This conservative tool does not increase the budget for realized or unrealized profits. A written plan can define a different rule.
Why reserve a safety cushion?
Stops, fees, slippage, gaps and firm calculations can create losses beyond the simple estimate.
Is this the same as a prop firm daily drawdown limit?
No. It is a personal planning budget and should generally leave room below any binding firm limit.
