Brent's bearish price rsi divergence on the hourly chart followed by a break below $52.00 levels indicates the prices could drop to $51.25 (hourly 100-MA) levels. A break lower lower could yield $50.89-$50.72.
On a larger scheme of things, bullish invalidation is see only if prices see a day end closing below $48.34 levels.
The hourly chart also shows a downtrend has been established, thus the resistance has to be taken out if prices have to re-test $52.00-$52.43 levels.
