The risk of a trade is how much you’ll lose if the stop triggers. On a $1,000 account, one percent is $10.
Why so little? Losing streaks happen to everyone, even experienced traders. Each time you lose 1% of what’s left. Ten such losses in a row — and the account has about $904, you can calmly keep trading. Ten losses in a row of 10% each — and about $349 will be left. To get back to $1,000, you’d have to almost triple it.
