What Traders Can Learn From A Professional Gambler About Managing Emotions

Cathy Hulbert is a professional ‘gambler’ who made a lot of money playing blackjack, slots and poker professionally over decades. I recently read the book ‘Gambling Wizards’ where she was  featured, among other professional gambling legends. One passage struck me immediately because adopting a similar attitude could help traders perform much better and avoid unnecessary mistakes. Let me quote the passage from the book:

How the professional prepares for a session

“Cathy: Before I go to play, I don’t engage in any other activity […] I don’t take phone calls. I don’t socialize. I don’t plan any social event afterward. I don’t want any time restrictions. I want my mind to stay as peaceful and restful as possible. I go to bed at exactly the same time every night and get up at exactly the same time every morning […] I don’t drink any alcohol the night before I’m going to play […] When I’m driving to the casino, I’m very aware of how irritated I am at other drivers […] The calmer I am, the better I know I’ll do […] If I’m driving like a maniac, if the light turns yellow and I’m rushing through, I’ll think, OK, you’re in a bad state today […]

Interviewer: Do you still play?

Cathy:  I play lower. I make a mental note to watch what’s going on with myself […] I don’t want to tak a $5,000 loss because I’m in a terrible frame of mind.”


Trading is a mental game

Become a Profitable trader

As a trader, you don’t have to be super smart, although you need to be educated to some degree, you don’t have to necessarily understand all macroeconomic factors, although it helps to form an opinion, and it’s not compulsory to be an avid accountant and being able to read through company balance sheets.

Although having a tested and sophisticated approach is very important, the difference between an amateur and a professional trader lies somewhere differently.The reasons for unnecessary and avoidable losses of amateur traders can often be attributed to the following 5 points:

  • Revenge trading: you open a new position just after your stop is triggered, without seeing valid re-entry signals.
  • Playing catch up: you want to make up for past losses, force trades and violate your rules.
  • You flip through your charts without really knowing what you’re looking for and then take trades that don’t meet your criteria.
  • You want to avoid losses and, therefore, widen your stop loss order or take it off completely.
  • You miss a trading setup and then jump in too late, although you should have stayed out by then.

If you are honest to yourself, you will know that you have probably engaged in at least a few of these 5 negative trading patterns. There is nothing to be ashamed of because most traders commit to the same actions and repeat their mistakes over and over again. If you objectively look back on your trading performance, most traders will see that the reason why they are not making the money they could be making is not because of the absence of a good trading strategy, but their repeated engagement in impulsive, emotionally caused trading decisions. It is safe to assume that most traders had a much better performance – some losing traders might even be break-even or winning traders – if they just had avoided the 5 previously mentioned mistakes.

Trading is a performance game and it’s not the trader with the most sophisticated trading strategy that will come out ahead, but the one who can control his emotions and attitude most effectively.



Self-awareness is a character trait that is important for being successful, not only as a trader, but in life in general. Self-awareness means that you are aware of yourself. This can include your strengths and weaknesses or your current state of mind and your emotional status.

Daily self-awareness and the ability to assess your current state of mind is important as a trader. Since being a trader means that you have to continually make decisions that can cost or make you money, and even result in major losses, making sure that you perform at your best level is important. However, most traders just see trading as a job where they HAVE TO sit in front of their desk from 9 to 5, regardless of how they feel.


Check your state of mind

The power of money

Every morning, before you start up your trading platform, take some time to assess your current state of mind. The following points can serve as a guideline to evaluate yourself:

  • Do you feel sick? Although it is obvious that you shouldn’t trade if you are sick, most traders don’t think that way and still trade as normal.
  • Have you had enough sleep? A sleep deficit has severe impacts on performance and how we react and interact with the markets. Dr. Steenbarger has a great article about sleep and performance. As a side note, this also holds true if you had too many drinks the night before.
  • Are you angry or aroused? An argument with your spouse or a serious conversation at work can, and will, carry over into your trading routine and will create a lack of focus.
  • Over-excitement, on the other hand, can also significantly influence your decision-making process. Being too euphoric can be dangerous because you might analyze risk wrong or are too casual about potential losses.
  • If you are coming from a winning streak, traders also tend to feel too confident and, therefore, be less risk averse. This usually leads to excessive risk taking.
  • On the flip side, coming from a losing streak can make you be too cautious and, therefore, make you miss potentially profitable trade.


To assess your current situation, observe how you react and interact with people and situations around you. The quoted passage from the beginning gives a few helpful tips how your actual behavior and perception of the world around you signal your current state of mind.



If you feel not too well and you answer most of the questions above in a way that signals that you are not in the optimal state of mind, don’t trade! Take the time before lunch off, or even take the whole day off. You will always get another trade, but you can’t get back the money that you lost by making an unnecessary mistake. Another way of avoiding unnecessary mistakes when you don’t feel well is that you trade smaller positions. If you normally risk 2% per trade, go down to 1% or 0.5% until you are sure that you feel better. Trading is not a business where you get paid by the hour, but by your performance.
