The ZigZag SupDem Zones Indicator detects support and resistance (supply and demand) zones using peaks and troughs formed by the ZigZag.
Depending on the timeframe used, it is necessary to set the necessary percentage to form a new peak or trough, by default that is set to 3%, ideal for most instruments on a unit of daily time.
The detection will be done only on the last periods set by the variable “lookback”.
The detection is validated if the indicator finds at least “minPoints” troughs or peaks not more distant than at most “threshold” in percentage.
- percent = 3 (percentage change of ZigZag to get new peaks and troughs, new swings)
- lookback = 200 (the period to search for supports and resistances)
- threshold = 1 (percentage to validate another zigzag from the one previously found to validate a support or a resistance)
- minPoint = 2 (at least it takes 2 swings of the same type, located one another less than “threshold” percent to validate a support or resistance)
