You are most definitely 'missing something.' The market is not fixed, not frozen, not immutable nor immune from outside influence or internally-driven structural change: what worked this morning may work today, may work next week and next month, and may, in the middle of April, dissipate entirely, leaving your positions/trading screwed until you respond. Ouchie! "B.T.D.T." [HA! Just looked, and you joined ET in 2010 -- so you've seen this.]
Plus your are not claiming any consistency. You made 200$ on one trade. How much did yo risk to make this money? And can you repeat it? Most likely whoever you took that money from will take it back as soon as you open another position.
It is that easy... For many reasons... 1) You trade 'once' 2) You 'limit' your losses 3) You pick a direction and you let your profit run 4) You 'reset' when you have a loss, with starting a 'new' day or period. 5) The loss is so small it doesn't bother you 6) You win can be unlimited All charastic of a fantastic system or trade approach. Good trading is effortless. Bad trading is all the rest.
Actually it depends on your approach, if you enter like a day trader, than most people wait much too long for conformation and enter late, only to be chased out because of there stop or low threshold of pain.
I just trade index's via a BB 12sma 2.2Dev, with some respect to a 80sma's direction, pretty good chop range most of the time and good for directional trade, KISS!!
What percentage of the trend did you make? Too little. Trend traders make it from fewer big wins, because they're more wrong than right. If you scalp it, you'll most likely being eaten by your losses, and slippage. Trading isn't easy, as you know.
That's very specific and applicable for only a minority of traders. I'm talking about trends that reverse, breakouts that fail and reverse etc.
