I have seen a few very successful large traders who trade on their instinct and judgement. They dont use any chart,Technicals or fundamentals etc but they have developed their instinct based on their experience and screen action.So the instinct here is not whims but a fine judgement which has come because of their long experience.They follow all good principles of trading like support /resistences ,getting out of a losing trade,MM etc without which they will not survive for long in this business. When I talked with them they knew supports and resistances of the day and of the week but unknowingly, without plotting it on the charts.
I am not blessed like these traders, so I dont trade on instincts.I trade on the charts only.
