The Australian dollar is more determined to fall this morning than it was on Friday or Thursday. The signal line of the Marlin oscillator goes below the lower boundary of its own channel on the daily chart. Obviously, the transition of the entire indicator into the negative zone is a matter that will be dealt in the near future. The aussie's closest target is 0.7641, then 0.7465 (or slightly below the development of the MACD line).
The four-hour chart shows that the price has overcome the MACD line, while Marlin is in the zone of negative values, the situation is completely downward on this timeframe.
