Regarding last idea the pair went from overbought zone begun to correct down towards the predicted key support. Now the pair shows oversold signs and the key support moved a little bit up from 1,2235 to 1,2249. If we see the pair USDCHF also is showing overbought signs that convalidates the pair EURUSD as they have negative correlation.
Below key support there is an opportunity to go long for a recovery.
Remember to do you homework and take your own decisions. THIS IS NOT AN INVESTMENT ADVICE.
