Script is showing potential reversal zones on chart, based on calculations of High/Low of selected period, smoothing it with selected type of Moving Average and applying Standard Deviation. Preferred to be used for contrarian traders. Another alternative usage would be to lock profit from open positions as this is very often early warning before reversal ahead.
