And sometimes even a stop loss will not be able to completely protect you, as the price can move so fast that slippage occurs and you lose more money than what you thought it was possible.
they are not playing it safe for the current market situation., lately, more and more futures traders are wrong in predicting their trades.
stop loss is also a good thing to use, but many traders ignore it. it can save us from bigger losses. but most traders are still optimistic that the market will move in the direction they predict.
And we have many examples of this, I have read countless examples of people that were considered to be genius traders and that almost never lost a trade, but when the day came in which they did their losses were so massive that they never recovered from such a huge mistake.
