(1) The white line with the dot on each daily candle is the Half-Back (HB) line. That line is the mid-point (50% retracement) of the prior day’s range. When price is in a strong trend it’s very typical for price to find support (in an uptrend) or resistance (in a downtrend) near HB. Some overthrow of that area is also relatively common. Below is the daily chart of NFLX. Six of the last ten days when price was moving higher (green candles), price found support at (or near) prior day’s HB. On the only red candle price found resistance at prior day’s HB. In addition to the HB points on the line the slope of the line gives a quick and easy way to see the current trend and whether price is strongly trending or not.
