10.17 Forecast Oscillator

The %F forecast oscillator by Tushar Chande shows deviation between today’s closing price and an N-day linear regression forecast (see Linear Regression) of that close. The deviation is expressed as a percentage of the close, so the formula is

     close - forecast
%F = ---------------- * 100
          close

forecast = linear regression of previous N days, at today

The N days prices for the linear regression start from yesterday’s close, and the forecast value is the line extended out to today. This forecast line is like the EPMA (see Endpoint Moving Average), but going out one day further. Chande suggests using a 5 day regression for short term trading, and that’s the default in Chart.
