As the name suggested, it is the irrational faith in one’s skills, methodology or beliefs. For example, you see a certain chart pattern and make a maximum leveraged trade, even though you understand that any chart pattern cannot predict market with certainty. Trading excessively after a winning streak also shows overconfidence.
It means finding excuses for something which makes you ‘uncomfortable’. For example, jumping from one indicator to another when you face losing trades; or continuing to trade in stock even your trading methodology does not gives you a positive expectancy.

For example, people begin to trade using RSI without understanding the internal relative strength; that is, RSI is most talked about on forums so start using them without rationally researching it. Being affected from attractive advertisement or intelligent sounding articles (including this one!) without due diligence also signifies availability bias.
It means giving yourself unwarranted praise for outcomes which may just be an outcome of chance. For example, people make money in a bull market through buy and hold and start begin to believe on their trading acumen rather than the market regime which favors their trading style. (more…)
