Biden??? WTF does politics have to do with it. If Biden had his way Powell would not be raising rates like he is. You can't accept the reality the dollar is going up. And note as an American I could care less what the dollar does other than how it might be affecting my trades, if like you ... I had guessed wrong. Price is agnostic. Just does what it does. Why, who cares other than those looking to point fingers away from themselves. JXY no idea?
Politics have everything to do with it. Politics dictates direction, price reacts according to it. Why do you think inside trading is a thing? Hypothetically speaking the Russians succeeded to show dominance, every country would reconsider where to put their money next. Everyone would start losing confidence in US as the "center of attraction". Then all of a sudden DXY declines. The less the world is dependent to US, the lesser the DXY's power. Have you heard of the New Global Reserve currency announced by Russia and China? I think DXY is exhausted and overrated unfortunately. But time will tell after all.
I don't what you mean by justify? Look at daily chart. It had a blowoff, interim likely, top. Massive profit taking. Broke down below 2 daily bar supports I had, only to close back above one of them. BTW I had a daily TD Sequential13 sell signal on $DXY on 10/7/22, as well as TD SetUp9 Sell signal on the weekly 10/14/22 so no big surprise what USDJPY did. Is this the start of a downtrend of any significance? TWT.
