You gotta respect ceilings (and floors).
Ceilings and floors are developed by traders targeting an old high (or old low) and stalling at the level. Why? Because risk can be defined and limited. If the price finds sellers against the ceiling without being stopped out, the reward can be a multiple of the risk. If you get stopped out, you lose a little. No one likes to lose but if you lose and little and stand to make "more than a little" when you win, you hope the wins are bigger than the losses and you win more than 50% the time. That is what traders try to do to make money..
Today, the AUDUSD continued the rally that was started yesterday when the price surged above the 200 hour MA (green line in the chart above). Today, the pair based against the 50% retracement and moved higher until the July 4th high was reached. Since then the pair has been consolidating above the 61.8% retracement at 0.7658 and the ceiling at 0.7682.
In the new trading day, those levels will be the risk defining levels. Move above 0.7682 and things are looking good for a move to 0.77119 high from June 30. Conversely, sellers here, would look for a move toward 0.7658. If there is a break of it, the price should look to retest of the 50% retracement level at 0.76414.
