//=======================================================================================================
// this script plots a stepping Moving Average of various types
// The steps are created when a "momentum change" - expressed by a "relatively significant price move" - has been detected - either up or down
// "Significant" is defined as a price move that is relatively large compared to the "recent" average (absolute) price moves within a certain period
// the "strength average" period can be adjusted, as well as the "significance" relative to that average
//=======================================================================================================
