The market has been responsive to these , including the often enough to place some degree of confidence in them as price barriers. Notice that the cyan extending from point C in the coincided with the 0.5 level from AP1 at the current time in the yellow circle. Now we're starting to see some confluence in signals.
AP3) This is a simple one. The green line which is generally falling throughout this chart shows a 100 day moving average. It too coincides with the barriers from AP1 and AP2 in the yellow circle. This moving average has potential to act as resistance as the market rises into it. It has provided on a number of occasions in this chart.
AP4 ) Finally, consider the oscillator shown at the bottom of the chart. It is set to highlight points where the oscillator exceeds a reading of 90 or is below a reading of 10.
