PMA (Pivot Moving average) is a set of 3 EMAs on HLC3 data.
When all PMAs are rising, market is considered bullish and the color of PMA becomes green. When all PMAs are falling, market is considered bearish and the color of the PMA becomes red. Otherwise, market is considered ranging and the color becomes orange.
It's also possible to set the resolution of PMAs. For example, you can see daily PMA of 15min charts. This way, if resolution of PMA is greater than resolution of chart, a vertical line shows the beginning of the PMA's resolution candles.
These PMAs are important components of Mark Fisher's ACD strategy.
