Amount of risk taken will be proportional to the size of buffer (above opening 320K) I have in my account and recent performance, subject to not exceeding the optimal fraction (Last year, the optimal fraction was 61% for options and 156% for stocks - did not use anything close to that in real trading).

Quote from neke:
Really putting in a lot of work into deriving a formula that should govern my leverage. It should depend on strategy, historical performance of strategy, buffer above starting capital, and recent performance of strategy.

That would necessitate ending this journal?
Quote from BlindLemonBoosh:
May I suggest a substitution of 'recent volatility of strategy' for 'recent performance of strategy' in your leverage formula?
Quote from bidask:
