Each trade that you take, you are actually risking your entire account instead of a fixed risk.
Your mindset on each trade will be dependent on the remaining balance of your account.
Trading without a stop-loss puts you into the "Gamblers Mentality" in which you are telling the market that you are positive that price will go in your desired direction. This is poor judgement seeing that the market is the Casino and has your balance outnumbered 99.999... to 1.
