The correct method for tracking the stock market is to use semilogarithmic chart paper, since the market's history is sensibly related only on a percentage basis. The investor is concerned with percentage gain or loss, not the number of points traveled in a market average. Arithmetic scale is quite acceptable for tracking hourly waves. Channeling techniques work acceptably well on arithmetic scale with shorter term moves.
