Dollar Index is approaching a resistance line of a falling parallel channel on a daily. Depending on the reaction of the price to that, I see 2 potential scenarios.
Bearish Because the index is currently trading in a bearish trend, probabilities will be higher that it will drop. To confirm that, watch a horizontal range on 1H time frame. If the price breaks and closes below its support, it will confirm the strength of bears. A bearish continuation will be expected at least to 101.5 then.
Bullish The market may break the resistance of the channel. If a daily candle closes above that, it will confirm the violation. A bullish movement will be expected to 103.0 level then.
