think you can money manage your trade by a very simple strategy.
Remember, with your average system you will have wins and losses. And the world is not beautiful, you may have 50-50 or more losses than wins.
To control your risk you should have something like “filter formula” or “signal strength” or “trade confidence” by allowing lower dollar value on less confident trades and vice versa. Ofcourse the parameters would have been set by you.
Lets say (example) you trade the market with a system consisting of elliot wave, candlestick patterns, fibonacci, divergence.
Each one is a rule. The more rules line up in your favour, the more confident, and higher pip value. But if only candlestick patterns for example give you a trade you would use quarter the risk.
