GBP/USD
The British pound did not dare to test the MACD line from below on the daily chart. The price is rapidly falling in today's Asian session. Surpassing the nearest low at 1.3823 from April 22 opens the 1.3610 target (lows on January 26 and February 2).
The price falls below the MACD line when the Marlin oscillator turns down on the four-hour chart. Since the 1.3610 designated target is quite low, then a more reliable condition for reaching it will be when the price transitions under the signal level of 1.3823, and not just consolidating below the MACD line.
