this chart i m sharing with u guys to present the 2 years trend behavior for the AUD.USD , we always seen a rally around 800 pips before a ret. which always goes to at least 38% ret. of the rally , and thats what i m trying to trade here , i believe we have witnessed the rally and we r witnessing now or about to witness the down correction of that rally , and as much as the rally goes , as much as the ret. goes , as example , if the rally was a 500 pip rally then the 50% ret. will be 250 pips lower but if the rally is a 800 pips rally then the 50% ret. will be 400 pips which makes it a better and more profitable trade .
please study the current chart as it gives everyone a better understanding of the trend behavior
