Here is the scenario: After meticulous planning and market watching on your part you enter a position. Almost immediately the market moves against you. Be honest now, What do you do? Hit the flat button; Keep calm you have a stop loss in place; Press the reverse button; Leave your desk you can't bear to watch; Look for any shred of info that will confirm your position; PANIC!. Please feel free to be as descriptive as you want! Think of it as release therapy.
