Despite the fact that most traders are fully aware of it, it is a curious notion that many traders seem to ignore money management all together or pay very little attention to it. The fact that most traders lose money in the markets is not really surprising if you consider that most of them also have no money management plans and mostly ignore the fact that they can lose money on any trade they will enter.
Money management is important, unless you have balls of steel, I have a balls of steel system that worked great in demo, no stop loss, buy at a reasonable price, pay attention to economic calendar, i won 99% of my trades the 1% loss were typos or not buying at a reasonable price. With real money i doubt there are many people who have the balls to not use a stop loss.
