When you're "In the zone" and got a good current feeling for the market and the current environment suits your trading style, intuition doesn't get beaten by any tools or indicators. It's one of those skills you evolve over time and some people are extremely good at this. The big challenge is to indentify when your intuition is wrong and to keep applying correct management. Because set ups can quickly get clouded by emotions or you end up over-trading when you think you're doing it simply on intuition. This is where a system and trading rules can come in handy, especially if you feel like you're losing that control or when you're a less experienced trader.
