That's his problem, he does not have that.

I entered the market with $26K in Feb this year, traded stocks for a few months and started trading es since May 11. A few weeks later I began to trade es exclusively.
I had some bad trading habits, and didn't follow my rules either, as a result I lost almost half of my precious capital in the past week, 4 losing days in a row:
09/09/2016: -9444 - I couldn't see this in my worst dream.
09/12/2016: -2542
09/13/2016: -481
09/14/2016: -343
That's 12,558 in total out of 25,726, 48.8% loss. I wouldn't make drastic changes unless it really really hurts. I decided to give it one last shot with new trading methods and new rules.
Some of my basic rules:
My daily profit target is $120, this is the minimal amount for me to survive. I have about $700 monthly income from my previous career. I withdraw $2K per month. I can't afford to lose.
- Trade one contract only.
- Both stop loss and profit target are two points, must be attached to a new order. Max loss of one trade is around $100. Stop loss order can be slightly adjusted if there is a major resistance/support level nearby.
- Max loss per day is $300, shouldn't be more than $350 under any circumstances.
- If the profit reached $200, max allowed retracement is $100.
- Follow the trend, trade break-outs. Never bet on tops and bottoms.
I use IB and Button Trader.

Paper trading is not for me, I can never get serious about it, I can only learn from live trading. I won't stop trading, if I stopped, that's it. Now I have the passion to learn, to trade, I love it. I force myself to stop it to save possible loss? That's just silly, very silly.
If at the end of the day I blow up my account, will I regret not to trade demo? Absolutely not.
PS: I lost all my money the first time I tried trading. I saved my money and tried again. I lost about half of my stake the second time. It was 14 years before I had a profitable year. Today, I think it could be learned in a year or two. I hope you hang in there until you learn how to day trade. It's a skill that can serve you well - in trading and in life.
