let me chime in.
I am new to trading, a few months as well, and am discovering all of the important concepts such as:
1) having a set of tools, ie trading strategies to work with to exploit different situations.
2) working hard to have a strong understanding of the underlying economies to get a general sense of inter-day direction and market psychology. This teaches how the market reacts to news.
3) don't fight the market. but also see the patterns and utilize them in your scalps. if you see selloffs (or buying) always hitting resistance, its likely all of those short scalpers looking for a quick buck (which explains immediate rebuying).
4) have an understanding of all of the tools out there and all of their quirks.
5) be very careful to attempt to understand your psychology while in trading and before. If you feel like you made a trade on an impulse and without any real systematic or fundamental guidance, get out and save yourself. Its happened to me where I've held optimistically, and it usually doesn't end well. Its very easy for a new trader to do this, especially if your past results don't result from this.
6) most important - manage your money and trade size properly. This seems obvious, but its really BOTTOM LINE the MOST IMPORTANT concept. Not only does it allow you to stay in the game, but it prevents 1 impulsive wrong trade ruining all of your other good results (that may have been more deliberate and well thought out).
I am too developing a system, based off of news reaction, momentum following, and fundamental market analysis. I'm trying to do a combination of short term (5 minute to all day) scalps on index futures and some key stocks that react to news predictably, using indicators like tick, volume, etc. Also I do some interday positions, moreso in options than stocks. (although my options activity is geared more towards selling premium than just buying lately. study hard and understand your risk before you do this)
I'm finding that while I like a quick profit from a scalp, its difficult to compete against the noise in the market. And to make money doing this, higher leverage (that I'm not comfortable carrying overnight) is required. My fault is I don't like to be wrong, and maybe yours too. Overtrading is another weakness of mine.
Yesterday's GDP news was a perfect buy signal. I bought ES before market open, as I saw all of my stocks were in blue (green for IB). Too bad I got out too early, but I'm still happy to profit. All the market wants is a stop to rate increases. This, and commodity (particularly energy) prices, are entirely driving the market right now. If the fed doesn't raise short term rate or signals a stop to doing it, that means we have a temporary bull run. But eventually the enthusiasm wears off, and either a shrinking GDP starts killing earnings, or a continuation of rising GDP does the opposite and once again stimulates fed raising (and thus bearish periods). Try thinking about these things. They will help... but don't go too far think the markets care about this on a 1 minute basis.
The concept: don't be the guy trying to short every pause and dip when oil is going through the roof if Iran cut off oil shipments to spite the west. Yes, it can be done, but most likely you'll lose most of the time. This is a perfect example of how fundamental analysis and short term technical analysis need to intersect. They are NOT entirely different planets, like some will have you believe.
The long term fundamentals eventually seep in to prices, and when they do, its usually pretty sudden. So be careful resisting breakouts. There's a whole strategy of buying at breakouts that exists, and your contrarian approach is weak in comparison.
Look at AAPL. Perfect example no clear signal to short it from its runup - as its earnings were the driving force. Don't fight the news. Doing well on good earnings, but if we have a recession, its down to 40. If we don't and oil comes down, we're up to 90. Don't just study charts - study underlyings.
If you want to short runups (or the opposite), then look for ones with absolutely no fundamental reason, no news, and no market correlation, no rhyme or reason.
Lastly - spend some time and try to exploit your psychological weaknesses (which it appears you are trying to do). Magnify them and conquer them one by one. Its the only way to go. Go to gamblers anonymous if thats what it takes. Otherwise you might be better off playing blackjack. Be proud of figuring out and solving whats wrong with you, and destroying that compulsive self destructive side of your personality. Think of it as therapy that earns you money.
Here's a good article on overtrading I just read.
