Good traders have a more active frontal cortex. If you put two people in a brain scanner, a normal person and a drug addict.
You’ll notice that when the drug addict sees a discarded bag of cocaine their midbrain lights up. When the normal person sees a discarded bag of cocaine their frontal lobe lights up. The normal person may consider taking the cocaine, or they may hand it over to a venue manager., they make a conscious choice. Trading is the same, an addict will see a bad trade and take it just because they feel like it. The profitable trader will look at the market and decide to come back later. They will never take a trade in bad market conditions.
