The main layers
A practical risk process
1
Define failure
Specify the daily, weekly, overall, and strategy-level outcomes that are unacceptable.
2
Set risk budgets
Allocate loss capacity across trades, ideas, strategies, and the account.
3
Size from invalidation
Calculate the position from allowed monetary loss and the distance to the point that invalidates the trade.
4
Check aggregate exposure
Include open positions, pending orders, correlated instruments, and common strategy factors.
5
Plan the response
State what happens at each threshold: reject new trades, reduce size, close risk, disable automation, or begin a formal review.
6
Measure adherence
Track overrides, sizing errors, slippage, technical incidents, and control failures separately from P&L.
Stop-based risk is an estimate
If a trader risks USD 100 between entry and stop, USD 100 is the planned loss, not a guarantee. Gaps, slippage, liquidity, commissions, currency conversion, and rejected orders can increase the realized amount. A safety reserve is part of the calculation.Risk management for prop trading
A prop trader must fit the strategy inside external daily and maximum-loss rules. The relevant capacity is usually the remaining loss buffer, not the nominal account size. Personal limits should sit inside hard breach thresholds and account for open P&L, fees, reset conventions, and correlated exposure.Position sizing
Convert a monetary risk budget into trade size.
Risk per trade idea
Group related positions under one cap.
Prop risk framework
Apply risk management inside funded-account rules.
Automating risk
Understand the benefits and failure modes of hard controls.
Risk controls can reduce the size and frequency of some losses. They cannot remove market, execution, technology, or counterparty risk.
