I'm trying to understand this 1%-2% risk of total capital rule that most traders follow. The way I'm thinking of it can't be correct, unless we all are starting with several hundred thousand to spare. I'll explain why.

5K is not much but if you have an edge in scalping you can make it but this is very hard. IMO 20K for futures and 30K for stocks is minimum to start with so you can do swing or position trading.
