What I look for is the waves in the indicators. For instance if you use
www.freestockcharts.com (which I do) you can almost see when a stock will upturn and down turn just by seeing farther back
Fmcc for instance is sitting low on the RSI indicator which means it should upswing soon. Now that may or may not be a large price jump when it swings but the waves are forseeable. Fmcc is a buy and hold right now. Of course voltility is a risk too it can drop off the face of the earth on bad news... Or jump up for no reason. But the wave indicators are better than just guessing.
Buy on the fear and sell on the good news! What goes up one day is down the next.
As you say computers now have algorithims for trading. You look on level 2 tradeing and a majority of buyers and sellers that are real people happen in the first few hours. After that you see manipulation going on in low volume. 10 shares or 100 shares trading in one direction or another to drive the price the direction the market manipulators want. Putting fear into the people or hope to catch ppl in at the top to only sweep it out from under the bag holders.
Its tricky.. I already got burned by YRCW and a few others and I would have done well but I was in over my head and on margin money. All those stocks are at a much higher price now and if I didn't get fvckin margin called on my losing stocks I would likely be rich right now.
Greed caused me to break my rules. Never trade with money you don't have. Can't hold stocks your loosing on for long term when your being margin called. Of course I learned all those bad mistakes when I first got into stock trading. Was a good tax write off tho!
However.. Trading stocks is like gambling but you have better odds if your trading and following some rules and learn to chart read.
