Chicago grain trader behind Keltner Channels

Chester W. Keltner

Chester W. Keltner (1909-1998) was a Chicago grain trader who described what he called the 'ten-day moving average trading rule' in his 1960 book How to Make Money in Commodities. The technique, now known as Keltner Channels, plots a 10-day average of typical price with bands set by the 10-day average daily range. Keltner made no claim to have originated it.

What they argue

  • A 10-day average of the typical price ((high+low+close)/3), bracketed by the 10-day average daily range, describes the short-term trend.
  • A close above the upper line is a buy signal and a close below the lower line a sell signal - trade with the break.
