The instructor is most likely telling you that 1% is the maximum loss you should take on any single trade. Its not bad advice. Many books mention a maximum of 1-2%. I think it also depends on account size. If you have a $100k account, then $1,000 is a lot. I would suggest starting small, just risking maybe $100 or 0.1% per trade. Or on a $10k account that’s $100. The reason is that you can have 100 losses before you lose your all your capital. It’s a steep learning curve that takes a lot of trades, so the longer you can stay in the game, trading and learning, the better. For myself, I start out with a $100 limit when I am beginning to live test a strategy. That includes commissions etc. Then when I get/stay profitable I add to this incrementally. Then my max is usually between 0.25% and 0.5%.
To this 1-2% single trade rule I would then add a 5% weekly rule as a secondary risk management tool. So if you lose more than 5% in a week then stop trading for the rest of the week, using this time to understand what went wrong, what can you do better, and observing markets. Then re-enter fresh the following week. The reason for this is because the learning curve has two components, number of trades and time, so this buys you time to learn and delays losing all your money.
Once you get profitable and comfortable trading then you can get more advanced and risk more capital. Then a good to start in understanding risk management is the Kelly Criterion. This basically tells you how much to risk based on payoff and probability. Keep in mind that Kelly assumes maximizing account growth, and the outcomes can be aggressive. Empirically you need to be cautious in estimating the inputs, particularly the probabilities. The successful experienced traders posting here about risking >2% will be comfortable with their calculations for payoff and probability.
