A while back there was an interesting TV series called “Breaking Bad”. It focused around Walter White; a chemistry high school teacher who breaks the conventional society rules to survive.
To survive in the stock market you follow the “Breaking Even” rule. Trading is all about probability i.e. chances of the stock price going up, down or sideways. The best probable action you take determines your success in the trading business. It requires you to protect your capital with a defensive guard at all times.
