$OIH - Oil Services, A Buy, But not $DXJ - WisdomTree Japan Hedged Equity ETF

The  Bollinger Bands are starting a contraction with a rising price line. The model likes $OIH. 

On the flip side, even with the strength in the Japanese market the models are giving me a sell.
Once the price line hits the upper BB then it's the start of a downturn.  Both upper and lower BBs are falling; the lower ever so slightly.
