Can it be possible for one to find an indicator or trading edge that is ridiculously simple? Over the last year I have been expermenting with various strategies and have come to the conclusion that the higher the time frame, less frequent trading, and really simple indicators go a long way towards profitable results. The thing is, it is tough to believe in them and put such strategies into practice, BECAUSE they rely on such elemental rules - you would think trading couldn't be so simple! Sometimes, one needs to immerse himself in formulas, programming languages, exotic trading platforms, etc. etc. just to provide a [false] sense of security. The industry has tried convincing people that only complex algorithmic traders and quants can survive in this evolving field. But yet I am still skeptic regarding their models, and have found that simpler forms of trading exist and provide a more efficient way to approach the markets. Are there any long-term profitable traders that still rely on basic discretionary principles to determine their positions in the market?
