This is all fancy ways to say the same thing...
Don't limit your draw-down or you will skew your trading edge. Take each trade as you would any other trade. The question should rather be after X% amount DD should I keep my balls of steel and continue without changing anything, or stop for a period of time until demo results have moved back to the expected.
Changing anything that is not already built into your trading strategy which has been tested will give a complete different set of results. Stick to what you know, and work on limiting by either stopping or continuing, keeping the actual trading strategy constant.
Just my thought.
You learn more looking for the answer to a question than you do being told the answer straight away.
