Traders fail to follow their rules because they don't truly have confidence in their ideas.
I front-run their own signals out of anxiety and wait for perfection in setups before they act.
My short-term needs often are for safety and security: I need to believe in what I'm doing.
Very often this problem occurs when traders have short-circuited their learning curves.
I am putting meaningful capital at risk before I've done the paper trading and small real-time trading needed to build a successful track record.
God damn it. I believe in my system when I see, in my own experience, that it works over time, across market conditions.
