"You will never go broke taking profits" is actually the opposite of nonsense. It is a very key element of being consistently profitable...
Depends how you define it. We have a different definition I think.
What I mean is:
You have a system with a certain risk reward ratio. An average profit per trade and an average loss per trade. Your backtests tell you when to get in and to get out for optimal results.
If you don't follow your system and take profits BEFORE the system tells you to do so, you will change the risk/reward ratio, the average profit per trade, and the average loss per trade. If you have a good system this will lead to smaller profits. Smaller profits that can drag your total result in a loss.
