For Trade War Pulse Proxy, Look to AUDUSDI wrote quite a bit about overall trade war sentiment here and in general I still do think that in spite of the influence officials may have on this pair it still may react negatively to trade war sentiment, but probably much more on potential capital flows if tariffs are put back into place.
But the easier way to find a relationship between trade war sentiment and markets is the proxy of AUDUSD. This price movement is much more reflective of that sentiment, which is rhetorically breaking down, since Australia's economy is much more dependent upon China's economy than most countries or major currency pairs.
For this pair, my forecast is with the trend in that it continues down in spite of Fed doveishness. Still trailing under the 200 day exponential moving average and RSI in addition to stochastic suggest we should sell.
