Quote from saliva:
Certainly I can relate to your plight. I know for a fact that this market hates me because I always miss a golden opportunity by a mere tick or I would get stopped out only to see it continue in my direction. As sad as this may be, I'm still trading day after day. As my mama always said, ya gotta have faith in yourself. 
Be that as it may, isn't it bit premature to judge an entire year's backtest based on one month's performance? Surely, you didn't have 12 straight positive months in 2009, eh? I bet ya January and February of 2009 were negative months. Anyway, market conditions have recently changed, so ya might need to tweak it a bit.
I turns out I did basically blow out my account.
Here is my performance for January from one of my accounts:
1/3/2010 233.03
1/4/2010 -321.66
1/5/2010 -286.16
1/6/2010 -858.06
1/7/2010 1093.80
1/8/2010 -682.5
1/11/2010 1272.19
1/12/2010 -490
1/13/2010 -1519.76
1/14/2010 -1049.20
1/15/2010 812
1/17/2010 466.06
1/18/2010 121.66
1/19/2010 1465.93
1/20/2010 -2397.04
1/21/2010 -330.12
1/22/2010 353.5
1/25/2010 -1084.02
1/26/2010 -593.08
1/27/2010 -2158.68
1/28/2010 -908.78
1/29/2010 -473.34
These results were from my system that I had backtested over a year. I trade based on an algorithm, so there's nothing discretionary at all, I set it and forget it. Because I'm theoretically not trading on emotion, and just base it on a set pattern, I technically should trade every day regardless of the losses I take because if the system works, it will eventually even out. If I were manually day-trading, then definitely I would have taken some time off after a few days of consistent losses, but since this is supposedly automated, emotions shouldn't have been a factor and don't cloud my entries and exits.
However, after those last 5 days of consistent losses, and 7 out of 8 trading losses in a row, your mind really starts playing tricks on you. Emotionally, I couldn't take the relentless losses, and I went cuckoo.
I started trading discretionarily on the 29th, after suffering another loss, I tried to trade the GDP reports, and got whipsawed by the action on that day and almost immediately lost about $3k on the ES. I turned off my computer and stopped trading for the rest of the day.
I've begun to question whether or not I have a gambling addiction, and whether or not I should be trading at all. I do trade on margin, but my stop losses are set at a predefined amount, so I was never in danger of blowing out my entire account. But I did suffer about a $15k loss this month, which is enormous for me, a 25% drawdown.
I'm seriously considering calling it quits, but I'm giving it one more month, and I'm cutting down the size of my trades. Obviously, I'm trading too much both in terms of size and quantity. Mentally I didn't and don't have what it takes to keep my cool after sustained losses. I was trading 1 contract per $10k in my account, and trying to keep my stop losses per trade roughly about 2% of my portfolio, but some days it got to more like 3.5% because of volatility. I've cut down on the number of contracts as well as number and quality of trades drastically, down to max 1 trade a day (down from 4 trades a day).
Obviously, one of my biggest concerns is that the system no longer works, for whatever reason, so I'll have to continue monitoring things throughout this month. So far, the results are mildly positive again, but it's still a long month. As you mentioned, maybe the thing that made it work so well last year doesn't exist anymore so if that's the case, then I guess I'll have to just chalk it up to bad luck and either try to find something new, or just live life the old fashion way and just save my money and rebuild my savings again.
