The move lower follows repeated failures earlier this week to sustain gains above the 50% retracement of the decline from the late-July high to the early-August low. That retracement comes in at $83.87 and has proven to be a key resistance level. The price reached $84.54 on Tuesday and $84.35 yesterday, but buyers could not extend the move higher.

More importantly, after crude initially moved lower yesterday, the subsequent rebound stalled near the $83.87 retracement level. That failure gave sellers the go-ahead to push the price back to the downside, and the bearish momentum has continued into today’s trading.

The latest technical development is the break below the 100-hour moving average at $81.39. Staying below that moving average keeps the sellers firmly in control and shifts the focus toward the 200-hour moving average at $79.47. That represents the next key downside target.

A break below the 200-hour moving average would increase the bearish bias further and open the door for additional selling, with the 200-day moving average at $76.66 becoming a more important longer-term target.

There does not appear to be a specific headline catalyst driving today’s decline. Instead, the move has been technically driven: buyers had their shots above the 50% retracement earlier this week and could not sustain the break. The subsequent failure at that level, followed by today’s move below the 100-hour moving average, has shifted the technical advantage more firmly in favor of the sellers.
