Trading with greed not only makes you unknowledgeable, and careless while trading with huge volumes of capital but also makes you more vulnerable to losses. Greed makes you think less and do random thinks mindlessly, in a desperate attempt to earn profits and double your money without formulating a strategy. Getting to know yourself is the key to successful trading; there is lots and lots of money to be made in the markets, but only if you learn to control your inner emotions.
