I'd like to know what trading style works best for you: trading on instinct or logic (to those who use both which is greater)? Although it seems that trading by a set of strict rules may seem to be the more rational way of trading, sometimes you can just "see" a bargain and want to scoop it up even though it may break your prior criteria. Other times those who trade on instinct sometimes get too involved in a particular security and either wait too long to dump a losing position (cause they "know" it will bounce back up) or cannot put the trigger when your system says to because you fear how it will turn out (aka opposite outcome). So which method do you trade and which method from your experience is better? (two different questions).
