I realize it too. Greed is the main enemy in forex for us. Every time when I see some advantages in forex trading, I think that will increase more. But unfortunately it decreased and I failed to get good profits. If I don't have greed, then I might get many benefits. So that's a lot of influence in forex trading. and I also lost my account more than 250 $ because of my greed to get a good profit. But then I became greedy, I traded taking high risks. I got a good profit in several trades but only one trade was wrong which caused me to margin call. So after that I learned the importance of trading with low risk and patience. Now I am a much better trader.
