The futures markets are quite merciless to those who don't know what they're doing. I've heard it said of the futures markets that there really is something called "beginner's luck". Many beginning traders have a string of lucky trades that boosts both their ego and their confidence. When they first begin, they have no fear because they don't know the pontential destructive power of the futures markets, so they trade without fear. They often enjoy a degree of success. However, every trader who has been around for awhile eventually gets burned badly by the markets. That's when these beginning traders learn some very excrutiating lessons. Most blow through their accounts and eventually drop out. If you don't understand the futures markets, and don't respect their potential for destruction to your trading account, you'll eventually be wounded -- badly!
