I have been holding United States Oil ETF (USO) and its been a pretty stead upward rise in the past couple of months. However, as WTI crude oil prices approached 50.00 last week, I noted that we should expect some "stickiness" or resistance.USDWTI Daily Chart 5/31(click to enlarge)Indeed, we have seen the past few sessions of price action being stuck around 50.00. On the daily chart, we also see a slight bearish divergence between price and the RSI. I am not strongly confident that price will retreat here at 50.00, but there is enough uncertainty to push me out of a long position at the moment. A long-term buy and hold strategy might be to hold and weather some short-term bearish correction potential. However, a shorter term swing trading style would prefer an exit here .USO Daily Chart 5/31(click to enlarge)I got in USO earlier in March after what I felt was a price bottom. After an entry just under 10.00, price went up but back down to 9.00, before taking off again. It is now around 12, and I feel like 20% is decent. Plus, as USDWTI is at a psychological level of 50 and a pivot, USO is also approaching a key pivot around 12.30. The daily chart already shows a potential bearish divergence. If price holds under 12.00 this week, I would be even more convinced about exiting. I am planning to exit around 12.00 today. If price does reach back towards 10.00, I think 10.00 could be a potential buying area. I would of course make sure USDWTI has the look of a bullish swing as well before going long USO again.
