There’s psychological evidence that suggests it’s human nature to become more risk averse after a series of losing trades and less risk averse after a series of winning trades, but that doesn’t mean the risk of any one trade becomes more or less simply because you lost or won on your previous trade. Example 2 – Once again, your trading account value is $5,000 but you are now risking 4% per trade (so that both examples start out with a risk of $200 per trade) : Remember, you have a risk to reward ratio of 1:3 on every trade you take. Important to note that after 4 trades, risking the same dollar amount per trade and effectively utilizing a risk to reward ratio of 1:3, using fixed $ risk per trade, the first traders account is now up by $800 versus $780 on the %4 risk account.
