Risk management is the operating system
A modest process can survive with controls. A strong idea can fail if each loss is too large.
Decide the loss before the entry
Risk management is the set of rules that keeps a sample of decisions from ending the account. Define the cash or percentage you will allow one idea to lose, then size the position to that number. Increasing size after a losing streak, or using a stop you do not actually place, is how a sequence of ordinary errors becomes a hole.
Drawdown is part of the maths
A string of losses is expected even when the process has a positive expectancy. If each loss is large, recovery needs an outsized run of wins. Measuring only the last profit hides that path. Correlated positions that point the same way are one risk, not three independent bets.
Stop the session on purpose
A daily or weekly loss limit is a rule for when you are no longer a reliable decision-maker. Write it before the session. The point is not to avoid every loss; it is to keep the next week available for practice. Profit without a drawdown record is an incomplete scorecard.
Takeaways
- Set the loss you will accept before you open the trade.
- Treat correlated positions as one combined risk.
- A session loss limit protects the sample you still need to learn from.
