Core rules
Risk Management Rules for Day Traders
Four rules the guides on this page keep coming back to. Write them down before the session starts.
Risk a small, fixed share per trade
A common guideline is to lose no more than 1% of the account on any single trade, so a run of losses cannot take the account out of the game.
Size every position from the stop
Work out the number of shares from the distance between entry and stop, not from how confident you feel. A wider stop means fewer shares for the same dollar risk.
Set a daily loss limit
Pick a maximum loss for the day, such as two or three times your risk per trade, and stop trading once you reach it.
Know the reward-to-risk before you enter
At a 1:2 reward-to-risk ratio, a strategy breaks even winning about one trade in three, before costs. Check the target is realistic before taking the trade.

FAQ
Trading Psychology and Risk Questions
What is trading psychology?
Trading psychology is how emotions, biases and habits affect a trader's decisions. Fear leads to missed entries and early exits, greed leads to oversized or late entries, and biases such as loss aversion make traders hold losing trades too long. Good trading psychology means following a written plan the same way after a win as after a loss.
What is revenge trading and how do you stop it?
Revenge trading is taking impulsive, often larger trades to win back a loss quickly, and it usually makes the loss worse. It is stopped with rules set in advance: a daily loss limit, a required break after a set number of losing trades, and no increase in position size after a loss.
What is the 1% rule in day trading?
The 1% rule caps the loss on any single trade at 1% of the trading account. With a $30,000 account, the most you can lose on one trade is $300. The position size then comes from the stop: $300 of risk with a $0.60 stop allows 500 shares.
How much should a day trader risk per trade?
A common guideline is 1% of the account or less per trade, and many newer traders risk less while they learn. The exact figure matters less than keeping it fixed, so that a streak of losing trades costs a limited, known share of the account.
How do you recover from a losing streak?
Stop and review before trading again, and check whether the losses came from broken rules or from normal variance in a strategy that still works. Reduce position size while confidence rebuilds, trade only your clearest setups, and return to full size after a run of trades that followed the plan.
Can day trading become an addiction?
Yes. Trading can become compulsive in the same way as gambling: chasing losses, trading more to feel the same excitement, hiding losses from family, or being unable to stop despite the harm. Stepping away and speaking with a doctor, a counselor or a problem gambling helpline can help.
