Learn to trade discretion.
I've never met a profitable system developer (self-taught or quants with Ph.Ds) who can't manually enter orders (aka. FOLLOWING RULES).
The issue, is you have to be risk-tolerant.
=======================================
In terms of a simple trailing stops, the key is to include, at least, volatility as a measure. Using a constant slope for trail stop has major pitfalls.
A good way to think of trailing stop is to reverse the mind set as, "Would you enter/reverse a trade with this exit signal?"
One newbie technique would be to test with a random entry and exit with the set of rules you have. Then test again, by tweeking the exit as a entry and use random exits.
