The index is making a pullback from the resistance level of 94.10 following Trump's announcement to cancel the summit with North Korea's leader Kim Jong Un. Current decline could be supported by the 200 SMA on H1 chart, where a rebound could take place in order to resume the bullish bias and to perform a breakout above 94.10. If that happens, then we can expect a rally to test the 94.88 level.
H1 chart's resistance levels: 94.10 / 94.88
H1 chart's support levels: 93.12 / 92.33
Trading recommendations for today: Based on the H1 chart, place buy (long) orders only if the USD Index breaks with a bearish candlestick; the support level is at 94.10, take profit is at 94.88 and stop loss is at 93.30.
