A fixed stop loss??? It's difficult to apply while you are trading in different market conditions like going with a trend, counter-trend trading, sideways, momentum and etc... Also, be careful when you take an advice from others because you don't know if they are a scalper, day or a position trader. Most are likely ending up to become an investor with a hope that somehow market will reverse back to their entry point.
You know. I spent a lot of time to improve my entry point where I expect to make money as soon as I enter a trade. If not, I'll cut lost once ENTRY RULES ARE VIOLATED. It's as simple as that. The moment I enter my trade, I don't get excited to see how much I'm making. I rather focus on my entry rules to see if they reverse.
