The world works on the basis of active trading and investing, but there are certain (low standards) conditions that need to met to achieve that, everyone aims too high hence they fail, intuition is based around passive trading which has no limitations but is completely inverted to the general lifestyle of most people, it's all very simple.
Buy Support, Sell Resistance, Trade with Stops, Use Tls and Channels when applicable! KISS! You can thank @Scataphagos later.
As far as I know, there's nothing bad in relying on intuition, but I suppose that there must be a mingle of intuition and analysis. If you suppose that the price this particular moment go up and there'll be a solid uptrend, then check out some macroeconomic data and check indicators. If the analysis turns out to be correct, then act. On the contrary, basing all decisions on the intuition isn't really good, because you can easily overdo. This day intuition tells you correct thing, the next one it will bring your loss streak. All in all, I should say it's dependable, and you can freely combine your gut feelings and rational sense.
