Define "constantly". I use 2 types of strategies: a conservative one, that never changes and focuses on long-term-stability. an an aggressive one, where i adjust some parameters from time to time.
Constantly means you have to curve fit your parameters when volatility changes.The 'parameters' your talking are probably stop losses/profit taking, right?
My strategies are adaptive to changing volatility, so adjusting parameters is not necessary. But - to maximize profit I have some aggressive short-term strategies, where I adjust the parameters for profit-taking every few months. How often do you adjust?
