Crude oil making another push against resistance

USO (largest crude oil ETF) has been in a wide trading range for the past 2 months between 71 and 79.

It's failed at all previous breakout attempts, but the more it tries and the longer this range carries on, the more likely the breakout becomes. No trade yet, but we're watching this zone to see if we can finally get some price expansion and volume on a move over 79.
