Professional option traders are statistically passive(That is, I don’t care how likely I am to win this time. I want to win, on average. This means that they want to win on average. A good option trader will frequently make a trade even though he thinks it will probably lose money. Frequency of winning is not the main focus, but payoff (odds) are. The inane slogan "You're only as good as your last trade" is dangerous. We can’t know what is going to happen all the time. We must remain statistically passive. You’re not right about a position nor are you wrong about a position regardless if the trade works out for you. Again, remain statistically passive. If I am in the business of trading options to make a profit, it is the statistical expectation that matters the most. On the other hand, bad option traders focus largely on frequency. They like the probability of the trade to heavily be in their favor, thus taking on remote hidden risks. If the PoP is 99.1%, the remaining 0.09% contains a ticking time bomb that will eventually explode, on average. Bad option traders have a string of "good" trades that bring profits and then get hit with the big kahuna. They blame it on something else and resume their old ways, not knowing that it will continue to happen again and again until they hit the "absorbing barrier" aka ruin. They're too anxious to win.
