Risk Management

Why accounts end from compounding habits rather than single trades, and how risk scales with the size of the account.


Risk management is account management. Look at the downside first and you keep enough of the account intact to take the upside when it shows up.

Nobody blows up on one trade

Traders rarely end an account on a single bad trade. They end it by compounding small mistakes that nobody managed. One bad habit, repeated often enough, becomes a terminal risk.

Nobody blows up on the first trade. Each loop is a small mistake that was never managed, feeding the next one.

Both loops have the same shape. A loss produces a feeling, the feeling produces a worse decision, and the worse decision produces a bigger loss. Breaking the loop anywhere stops it. Breaking it at the first step costs the least.

Risk scales with the account

Your rules are not someone else’s rules, because your account is not their account. Set risk as a percentage and let it follow the size you actually trade.

Small account

  • Smaller margin for error
  • Limited buying power
  • Patience matters more
  • Good faith and pattern day trading violations are a bigger risk

Both

  • One bad trade can wipe out weeks of progress
  • Risk is set as a percentage, not a dollar figure
  • Size follows the account and the trading style

Large account

  • Larger margin for error
  • Little to no buying power constraint
  • Can be margin called
  • Those violations are less likely
Risk rules scale with the account. The middle is true whatever size you trade.

Not every day deserves the same size

Some days are better to trade than others. Think of it the way you would a television series: some sessions are filler, and some are the payoff from months of setup. If you are going to size up at all, do it on the second kind. Those days usually involve:

  • A key level breaking after weeks or months of consolidation
  • The major indices and related sectors breaking key levels too, or showing very strong price action
  • Follow through across the indices, the sector, the stock in question and its peers

Outside those conditions you can still trade. What you should not do is put size behind a day that has not earned it.
