Some traders confuse trading with gambling. They start to focus on the winning and losing instead of the decision-making. And that will assuredly lead to ruin — the unfortunate situation where a trader blows up an account.
The same lack of discipline that will allow an account to grow from $50,000 to $1 million in six months will cause it to fall from $1 million to $10,000 six months later. It's almost guaranteed.
If you can't trade disciplined in a one lot, adding size won't help.
This episode of Coach's Playbook talks about how traders can avoid the gambler's mentality and maintain their bankroll for prolonged success.
