Buyin Waste Management

Bought some Waste Management (WM) today. I'm trying to get a feeling of this market, and passive observation doesn't work so far. WM was one of the stocks in 4x2 signal today. This system isn't working anymore, but together with other signs can help. I wanted to buy something, because current pattern is down on Monday and Tuesday, turnaround on Wednesday, up on Thursday and maybe on Friday.
Of course it might not work. It's trading, not winning.
