Risk Per Trade

What is risk per trade?

Risk per trade is a rule a trader sets in advance defining the maximum percentage of their account they are willing to lose on any single position if it goes wrong. It is typically expressed as a small, consistent percentage — commonly 1% or 2% — rather than a fixed dollar amount, so the risk automatically scales up or down as the account balance itself grows or shrinks.

This figure is the starting input for position sizing: once a trader knows how much they’re willing to risk in dollar terms, they can work out how large a position to take given the stop-loss distance on that particular trade.

A worked example

A trader with a $20,000 account who follows a 1% risk-per-trade rule risks $200 on each position, regardless of which pair or setup it is. If the account grows to $25,000, 1% risk automatically becomes $250 per trade; if a rough month brings the balance down to $18,000, 1% risk shrinks to $180. The percentage stays fixed while the dollar amount adjusts with the account.

Compare this to a trader risking a flat $500 on every trade regardless of account size — on a $5,000 account, that’s a reckless 10% per trade, while on a $50,000 account it’s a much more modest 1%. Percentage-based risk per trade avoids this kind of inconsistency.

Why it matters

A consistent risk-per-trade rule is what makes a string of losing trades survivable rather than account-ending. At 1% risk per trade, ten losses in a row cost roughly 10% of the account (slightly less, since each loss is 1% of a shrinking balance) — painful, but recoverable. At 10% risk per trade, the same losing streak would come close to wiping the account out entirely. This is why risk per trade is a foundational input to both position sizing and broader money management.

Quick recap

• Risk per trade is the percentage of account capital a trader is willing to lose on any one position.
• Common values are 1-2%, chosen as a fixed percentage rather than a flat dollar figure.
• It scales automatically with account size, keeping risk proportionate as the balance changes.
• It is the key input that drives correct position sizing.
