Cash,
Be proud that you have the guts to post your truth on this board and get feedback, hopefully mostly positive.
A few years back I started position trading futures. I lost 6 k, then funded another account with 20k, made 65k at one point, gold went against me and closed at 29k. I took that 29k and shorted crude and got my ass handed too me. I finished -6k. This was when I was working full time making good money in sales.
Last year, with the support of my wife, whom pay our bills, I quit my job and made a full time go at day trading index futures and currencies. I have been tradin live money about 5 months. I started with 5k, to get the hang of it, and I am down $300 after commish. I got some training, hired a mentor, and received some free training from another friend/mentor. I have realized what my problem is and now taking corrective action.
I see the setup, hesitate sometimes, sometimes not and get up $50-100 a day and stop because I am afraid of losing. That is because I have a couple of winners and then get whacked and I am negative because my R to R is unbalanced. My point being is you need to constantly be asking yourself why are you taking this trade or not taking this trade. You need to type up a trading/business plan and stick to it or stop. Last week I almost revenge traded, but did a reality check and shut down and left before I did something stupid. How are you emotions?
Find a time frame and stick to it. I spend last night reading all of the post by the Super_Ego and got some good confirming ideas I already knew something about. They are summarized here is the link if you are interested

I am honestly questioning if I can day trade futures or should I consider swing or position trading futures or stocks. It takes alot of discipline to pull the trigger multiple times a day. It is even harder to keep pulling the trigger after you are down a few hundered for that day. My friend whom has been full time trading for 2 years told me this. When he first started he went -10k before he trade to break even. From there it took a few more months to make money, first $50 a day, $100 day, now he can make $200 day easy, maybe not in the summertime right now though

. This is an evolution, it will not happen overnight so don't beat yourself up.
I think the keys to trading success are mainly fourfold, but chime in folks if I miss something or disagree.
1. Find something that works for you and be consistent. simpler is usually better.
2. Test it very rigoursly. Back and forward test. Take notes during the day. How far did it move etc..
3. Spend and invest in whatever helps you get your mind in the zone to trade. I myself and going use some NLP subconscious programming tapes. There are good book on trading psych... Douglas Kiev etc. Think what you want they have worked for me.
4. Have a written trading plan and follow it to the letter.
I had a written trading plan, it wasn't working, found some new techniques, starting making money, didn't re-write the plan and pretty soon starting taking trades that weren't on plan. I started losing more money. Why because I no longer had a plan I had committed to follow. I was all over the board and frankly Nathan you seem to suffer from a similar dilemma.
Ok enough of my rambling. Thanks for starting this thread it forced me to reveal my weakness to a sometimes hostile board. I hope something I said help you or someone else.
