Trading according to your rule and method is the best thing as that would not give you a chance for
'I should/would/could have done that..' You make profit or loss.. is part of business.. but you win when you answer
'Yes' to question
'If you followed your rules?'
Now... Instinct...I guess is something that comes with years of experience with charts(I cant think beyond charts
). Many times i have experienced that my mind is telling me something about a particular movement but it is not there in my rule book. I follow that with strict MM (MM should always be strict, rule or no rule). Most of the times that works out. I go to various timeframes that i follow and I notice that there was strong or mild signal on charts too.... Now after years, I have some rules which came as an instinct and produced same paterns on chart and are now part of trading rule.
How does this happen? After years of experience, I guess our subconscious mind keeps recording patterns that we might not be aware of and gives us a signal when the pattern repeats. You trade chart or clear tape, subconscious mind can not record something that is not repeated or will delete it if it doesnt repeat. So keep following your method and rules, when your instinct tells you something try to find on chart if it repeats it will become a part of your trading rule. If your instinct tells you to do something, and there is nothing there on chart, leave it. Let it move even if it goes in the direction your instinct told you. To be successful, you dont have to catch every move.
Last thing, what i said about the instinct above should be applicable to people with minimum two years experience with same method.
Otherwise we have numurous example where 'instinct' have made people beggars
