EUR/USD, H1 time frame:

The internal structure of the downward wave (Y) is observed in the last part of the hourly time frame. This wave takes the form of a simple zigzag A-B-C. Now, the final impulse wave C is being formed, which is marked in green sub-waves [1]-[2]-[3]-[4]-[5] (they are in circles on the chart). To date, the first four sub-waves have been fully done.

Meanwhile, the last fifth wave, that is, sub-waves [5], is expected to form in the near future. It is assumed that it will be a simple five-wave impulse (1)-(2)-(3)-(4)-(5). The internal structure of this impulse is shown schematically in the chart. Most likely, the price will decline in sub-waves (3)-(4)-(5) to the level of 1.1688, namely under the low marked by the current wave [Y], which is not visible on the chart.

At the specified price level, the value of the impulse wave C will be 100% equal to the value of wave A. There is a high probability of reaching this level, so this is a good trading opportunity to sell.
