I too, as many others on this thread, have spent alot of time using various indicators only to find that nothing really works in every situation. The search for the holy grail can be fustrating, not to mention expensive. In the end it's really a combination of gut feeling and mechanical analysis that gets the job done. Those that can go simply on gut have simply internalized some basic analysis and no longer conscienously think about it. Let's face it, going on gut means that one has identified a possible oversold condition, or a top forming, or cleanly trending prices on high volume BUT without having to use a chart loaded with indicators to make the identification. This only comes from experience (provided one is consistently profitable and not gambling). This comes from watching market behavior day in and day out. For some this works, but for others the action of the market, the gyrations, the false breakouts, the noise, all cloud the picture enough that they can't see what's really going on or simply don't feel comfortable relying on just a gut feeling. For those, technical analysis helps filter out that noise so they can see a clearer picture. Ultimately we are all seeing the same picture........right? The time and sales are the same for all of us. But it's how we interpret that information that makes all the difference. As I've mentioned, some with experience, have internalized the analysis of the information while others prefer the structured nature of technical analysis to provide guidelines within which to work. However, pure technical analysis in the form of a holy grail is not possible or we'd all be using it. In fact it's not possible for us all to use it. If we all saw a short, who would buy it? In addition, if it were that mechanical, trading wouldn't be one of the most difficult professions in the world, would it? So there is a place for both in each of us, and each will have them in a different ratio.
I'd say I'm 80/20 (hard analysis/gut). I've developed a simple combination of technical analysis inputs that seem to be reliable under most circumstances. Basically, I've customized ordinary indicators into a system that serves as a framework for my trading but is always subject to my gut feeling at the time. The hard analysis gets you in the ballpark, but reading the tape and the "feel" of the market before entering and exiting a trade is the final step before pulling the trigger. I think simple is the key here. Too many indicators only complicate the matter, and trading is best left simple or you'll end up with analysis paralysis. Managing the trade then becomes critical. With my system, the same methods apply: technical analysis provides the framework, but go with my gut as the final yea/nae.
Please excuse the rambling!
Good Trading!
