Understanding Pain & Regret

Pain & Regret are two powerful emotions in Trading. Market always ferrets out traders' weak points and exploits them to extract maximum energy.

1. I think after all Fundamental and technicals , the edge of a trader lies in his observation of other traders and self observation of these two emotions.
2. Pain of a position going against the trader, Regret of exiting early from a profitable position these two emotions can be used to the traders' advantage.
3. Today I have traded IOC trying to fade consensus bullishness in the stock. Traders are citing reasons of Oil India listing as trigger for the stock. I had a hypothesis of price already reflecting that news.
   
4. IOC opening was weak relative to market and also in the context of price appreciation in the previous days, I shorted the stock for a 2% gain.
