I remember Quallamaggie said in an interview that where other traders may scale down as their account grows he would simply keep increasing size while maintaining the same % risk, i.e., compounding profits.
Also, I'm sure he traded way more aggressively than 1 % per trade in his early days and would also scale into a trade for a bigger position size while keeping initial risk small and risking unrealized profits for a larger win as he increased his size. This works well when the market is in an extreme bull phase and stocks are making substantial one way moves.
Example:
5 % gain per week per $10 000 of capital in your account. You start with $10 000. As you hit $20 000, you double your position size (while keeping the same risk %). At $30 000, you add one extra unit for a total of three and so on.
After one year (50 weeks), you have $72 500 in your account gross.
After two years (100 weeks), you have $782 500 in your account gross.
Idealized example, of course, but it shows the potential of increasing your size as your account gains more buying power. Of course, you need to be a consistent winner to accomplish this. Initially, growth is slow, but at some point it starts snowballing.
Substitute 5 % gain per week with 0.5 % if you want. Over time, it will still yield an impressive result.
At the end of the day, there's only a few Quallamaggies and Zangers per every generation of would-be traders, though.
