Stochastic Indicators Part 2

The second line, %D, is a smoothed version of the %K line. The normal value is three periods.

The %D formula is %D = 100 X (Hs/Lg)

Where Hs is the three-period sum of ( C - A) and Lg is the three-period sum of (Hs - A). The momentum indicator that results from these calculations is two lines that fluctuate between 0 and 100. The %K line is usually plotted as a solid line, while the slower %D line is usually plotted as a dashed line. A good way to differentiate between them is to think of the fast %K as "kwick" and the slow %D as "dawdle."

The popularity of the stochastic can no doubt be explained by the smooth manner in which it moves from an overbought to an oversold condition, lulling a trader into a feeling that price trends are much more orderly than would appear from an observation of an RSI or an ROC indicator.

Longer-term time frames, used on monthly and weekly charts, appear to work much better than the shorter-term stochastic indicators used on daily futures charts. Overbought and oversold bands are usually plotted in the 75 to 85 percent area on the upside and in the 15 to 25 percent area on the downside, depending on the time span in question.

An overbought indication is given when the %D line crosses the extreme band, but an actual sell alert is not indicated until the %Kline crosses below it. When the two lines cross, they behave very similarly to a dual MA system. If you wait for the penetration, you can avoid getting trapped into shorting a strongly bullish move or buy­ing into an extremely negative one.
