About 10 years ago I Turned $2,500 into $5,000 in just over a month with a new stock system. Thinking I was the next George Soros, I took on $25,000 from impressed friends, and lost $20,000 of it over the next 6 months. This was when I was making $25,000 per year at a job. My wife wasn't impressed.
Well, maybe it's not a "great" mistake, but I certainly felt stupid. I had just re-arranged my charts the night before. If I recall correctly, I ended up trading MWD based on the chart of C. Didn't go well
I did that once. Two stocks ~$27.25. Bought one then marked the wrong chart and followed it for 15 minutes before I realized it. Fortunately the one I owned didn't move.
That one pissed me off because I had my father uncle and like 3 other people in my family stacked into it... I went and sold it for 4 ts. and every day for like year and half had to listen to them keep thanking me!!!! sons a bitches!
That's how I built up my second grubstake. The mistake contributing to my first grubstake was : http://www.elitetrader.com/vb/showthread.php?s=&postid=95152#post95152 Which grubstake am I currently on? Hey, do you ask a lady her age?
