Daily Risk Calculator

• Balance at Start of Today is your balance before today's trading. Every percentage is a percentage of this balance.
• Daily Loss Limit is the most you allow yourself to lose today, as a percentage of that balance or as an amount. Changing the unit clears the value.
• Closed Trades Today is the combined result of today's closed trades after costs. Choose Loss or Profit and enter 0 if there are none.
• Open Trades is the total loss from entry if every open trade hits its current stop loss, including estimated costs. It is the full planned loss, so do not also subtract floating profit or loss. Enter 0 if there are none.
• Next Trade is the loss you would take if the next trade hits its stop loss, including estimated costs.

You set the most you allow yourself to lose today. The calculator takes that limit, subtracts today's closed loss (or adds closed profit) and subtracts the loss your open trades would take at their stop losses. What is left is your allowance now. Subtracting the next trade's loss shows the allowance after it.

• Allowance Left Now = Daily Loss Limit + closed profit (or - closed loss) - Open Trades loss at stop loss.
• Left After Next Trade = Allowance Left Now - Next Trade loss at stop loss.
• The status says the next trade fits when its loss at stop loss is no larger than Allowance Left Now. If it is larger, or if no allowance remains, the status says the limit is exceeded or used up.
• Possible gains on open trades are not counted. A negative result is shown as a negative number.

This tool does not read your account, add costs for you or check any broker or prop firm rule. Include any costs you expect in the figures you enter.

Many prop firm accounts have a daily loss limit, and firms word and measure it differently, for example from the balance at the start of the day or from equity. This calculator does not apply any firm's rules. It uses the balance at the start of today and the planned loss of your open trades at their stop loss, as described above.

Read your firm's rules, then enter a Daily Loss Limit, as a percentage or an amount, that matches how your firm measures it. If you want a safety margin, you can enter a limit smaller than the firm's. To find out how much you can risk on the next trade, size it first with the Position Size Calculator, then enter that planned loss as the Next Trade.

With a 10,000 balance at the start of today and a 5% limit (500.00), a closed loss of 200.00 and 100.00 at risk on open trades leave 200.00, or 2.00%. A next trade risking 1% (100.00) leaves 100.00, or 1.00%, so it fits the limit.

Use the same figures as above (10,000 balance, 5% limit, closed loss of 200.00, 100.00 at risk on open trades), which leave 200.00 or 2.00%. If the next trade risks 3% (300.00), it is 100.00 above the allowance left now. The tool shows Left After Next Trade as -100.00 (-1.00%) with the status Proposed risk exceeds the entered limit.

Closed profit counts toward the allowance. If today’s closed result is a profit of 150.00 instead of a loss, the allowance left now is 500.00 + 150.00 - 100.00 = 550.00 (5.50%). Whether you want profit to extend your daily limit is your own rule: the calculator simply follows the figures you enter.

If the closed loss is 400.00 and open trades risk 100.00, the whole 500.00 limit is used. The tool shows 0.00 and the status No allowance remains, and any new risk would go past the limit.

Use digits 0 to 9 and a dot for decimals, for example 1250.50. A comma is accepted only to separate groups of three digits, as in 1,250.50. A number cannot start with 0 followed by a comma, so write 0.5, not 0,5 or 0,500. Spaces before or after the number are ignored. Spaces inside a number, signs, currency symbols and digits from other scripts, such as Urdu-script digits, are not accepted.
