Usually trading system with many indicators say a complex system, otherwise the trading system with little indicator or even do not have called simple system. The problem is whether a complex trading system provides more accurate prediction compared with the trading system with a few indicators. If the answer is that complex systems can not guarantee to give better results than the simple system, then surely many people who chose a simple trading system (with one / two indicators), including me.
I personally prefer to use as little as possible indicators, if possible I want to use onl;y one indicator like what I wrote in another threat about Beginner Alert. How do you think?
