Risk Management in Trading

Risk management is the part of trading that decides whether a trader is still trading in a year. Entries are interchangeable; exposure is not. A method with a modest edge and strict risk control survives a bad month. A method with a strong edge and no risk control does not survive one bad week.

The arithmetic of drawdown

Losses and gains are not symmetric. A 10% loss requires an 11.1% gain to recover; a 50% loss requires 100%; a 75% loss requires 300%. This asymmetry is the entire argument for small, fixed risk per position.

Position sizing from invalidation

Correct sizing runs backwards from the exit, not forwards from enthusiasm. The sequence is:

1. Choose the maximum percentage of the account you will lose on one position — commonly 0.5% to 1%.
2. Identify the invalidation price where the idea is objectively wrong.
3. Measure the distance from entry to invalidation.
4. Size = risk amount ÷ distance per unit.

On a 10,000 account risking 1%, the risk amount is 100. If invalidation sits 50 points away and each point is worth 1 per unit, the position is 2 units. Widen the stop and the position must shrink. Nothing else in the process changes.

Leverage, margin and close-out

Leverage does not create risk on its own — position size does. But leverage makes an oversized position possible, and it introduces a second failure mode: forced closure. When margin falls below the platform's threshold, positions may be closed automatically, at the market's price rather than the trader's. A plan that is theoretically sound can still be terminated by a margin rule the trader never read.

This is one of the concrete reasons platform documentation matters. Margin schedules, close-out levels and negative-balance handling are structural facts about a trading environment. Our how trading platforms work guide explains where those rules live, and the full Fjord Markets review shows how we frame those questions for a specific platform.

Portfolio-level exposure

• Correlation. Four long positions in correlated instruments is one position with four tickets.
• Aggregate risk cap. A total open-risk limit — for example 3% of the account — prevents accumulation by increments.
• Daily and weekly stops. A hard stop for the session ends the tilt spiral before it becomes expensive.
• Event exposure. Scheduled announcements can gap through protective orders; size accordingly or stand aside.

Reward-to-risk and expectancy

Risk control and expectancy are the same conversation. If average winners are twice average losers, a 40% win rate is profitable. If they are half, even 60% is not. Recording the ratio honestly is more informative than any indicator setting — see trading strategies for beginners.

The behavioural layer

Most risk rules are broken, not miscalculated. Moving a stop, doubling into a loser and re-entering out of frustration are decisions taken under pressure by someone who knew the rule. Written limits, pre-set orders and a mandatory pause after a loss exist precisely because judgement degrades exactly when it is needed. More on this in trading psychology, and on why market conditions change the required headroom in understanding market volatility.

A minimum viable risk policy

1. Fixed maximum risk per position, written down.
2. Invalidation defined before entry, always.
3. Total open risk capped across all positions.
4. Daily loss limit that ends the session automatically.
5. No size increase after a loss; review before any increase after a win.
6. Weekly review of every deviation from the above.
