I see the price action today follows the 100-500 share lot trading quite well. As soon as I put in a buy, a pro puts in a 100 or 200 above me.

Something I don't understand, from ElPrimero's list (we've had it before here too):

100 I need shares.
200 I need shares badly, but do not take the stock down.
300 Take the price down so I can load shares
400 Keep trading it sideways.
500 Gap the stock. This gap can be either up or down, depending on the direction of the 500 signal

..... so what's the real difference between 100 and 300? Both ways, the manipulator wants the price down so he can load up. What's the diff?

..... ditto 200 and 400 - nearly the same? It's a signal of "don't do anything please guys"
