This is just some random thoughts.No you don't, but you have to study and define risk management, you stop competing against Hedge funds and make it a self competition, you become highly knowledgeable on hedging and not just options, sometimes you have to use stock options or stocks themselves to hedge various commodities as they lack options. Like I got short Lumber and waiting to add to my shorts, without the hedges it be playing with fire.
And yes, I agree with positive expectancy, but mine is way different than most, I have zero caring about winning percentages and just concentrate on finding ways to have as low as I can go regarding losing percentages and amount of drawdowns.
Risk management, two different scenarios:
1. One trading approach I found seldom used except by someone like Taleb is an approach used by venture capitalists: To get payoffs from high payoff but low probability ventures, you need to invest (e.g., long DOTM options) in lots of them. A 1-10% wins in those cases will have handsome payoff.
2. The opposite for high probability of win cases, with steady low payoff but a few times with huge losses (e.g., write naked OTM calls and puts): You leverage like hell for a few trades, then take your money and run - stop trading. Think Karen the super trader stopped after she made $10-$20 M laughing all the way to the bank instead of kept going at $50 M, $100 M, then went broke.
