Distance-to-Bust Explained

Distance-to-bust is the real number every prop trader should know before entering a trade.

It is the distance between the current account balance or equity and the account failure line. If the account has $2,000 of drawdown room and you risk $400, you are risking 20% of the survival budget. Not 0.8% of a fake $50K headline account. Twenty percent of the thing that actually matters.

This one metric cuts through almost every bad decision.

Oversizing, overtrading, trading near daily loss, forcing the last trade near target — all of it becomes clearer when you ask one question: how far am I from bust?

Quick definition

Distance-to-bust is the amount of room between where the account is now and where the account fails, locks, liquidates, or becomes ineligible under the firm’s rules.

Formula:

distance-to-bust = current account value − failure threshold

The hard part is knowing which “current account value” and which “failure threshold” the firm uses. Some rules use balance. Some use equity. Some trail intraday. Some update end of day. Some lock at starting balance.

Why account size lies to traders

A $50K prop account sounds like a $50K account. It is not.

If the max loss limit is $2,000, the trader’s practical risk account is $2,000. The headline size may define buying power or account tier, but the drawdown rule defines survival.

That is why traders get trapped by percentage rules copied from personal-account trading. Risking 1% of a $50K headline account means risking $500. If the drawdown room is $2,000, that is 25% of the distance-to-bust.

Four full losses can put the account at the edge before commissions, slippage, or emotional mistakes.

Distance-to-bust example

Imagine a $50K account with a $2,000 max loss limit.

• ▸Starting account: $50,000
• ▸Failure line: $48,000
• ▸Distance-to-bust: $2,000

If the trader risks $100 per trade, the account has about 20 planned losses before the failure line, before costs.

If the trader risks $400 per trade, the account has about 5 planned losses.

If the trader risks $500 per trade, the account has about 4 planned losses.

This is why the same setup can be reasonable at one size and reckless at another.

The metric changes as the account changes

Distance-to-bust is not static.

If the account builds cushion, distance-to-bust may increase. If trailing drawdown moves up, distance-to-bust may not increase as much as the trader thinks. If a payout locks the drawdown line or reduces balance, the post-payout distance can change again.

That means distance-to-bust should be checked:

• ▸before the first trade of the day;
• ▸after a big win;
• ▸after a loss;
• ▸near the profit target;
• ▸before a payout request;
• ▸after a payout;
• ▸after a reset.

Distance-to-bust versus daily loss limit

Daily loss limit and distance-to-bust are related, but they are not the same.

Daily loss limit is the amount the firm allows the account to lose in a day before a lockout, breach, or pause. Distance-to-bust is the total room to the account’s failure threshold.

A trader can be far from bust but close to daily loss. A trader can also be inside the daily loss limit but dangerously close to total account failure.

Both matter.

Common mistakes

• ▸Calculating risk from account size instead of drawdown room.
• ▸Forgetting trailing drawdown can move the failure line.
• ▸Using the firm daily loss limit as the personal stop.
• ▸Not recalculating after a big open-equity move.
• ▸Taking payouts without understanding the post-payout account cushion.
• ▸Increasing size near the target because the account is “almost done.”

The Bucko distance-to-bust checklist

Before entering a trade, write down:

1. ▸Current account value:
2. ▸Current failure line:
3. ▸Distance-to-bust:
4. ▸Personal max risk per trade:
5. ▸Personal max loss for the session:
6. ▸Planned stop distance:
7. ▸Dollar risk per contract:
8. ▸Contract size:
9. ▸Worst-case loss including slippage:
10. ▸New distance-to-bust if this trade loses:

If the last line makes you uncomfortable, size down.

Bottom line

Account size is marketing. Distance-to-bust is reality.

The traders who survive prop firms do not just ask, “How much can I make?” They ask, “How much room do I actually have if I’m wrong?”
