 Hi All
Just wondered if anyone who has created this for TC would mind sharing the code. I've had some pretty good luck using it with another program with the default settings of 14 and 3. Thanks.

 Here is the code.

S = "smooth" parameter
N = "period" parameter

HH = highest high for last N periods
LL = lowest low for last N periods

V = 100*(Close-LL)/(HH-LL)

DSS = EMA(V) for S periods

Thanks.

 The provided formula would seem to be one of the following (probably the second):

S = 14, N = 3:

XAVG(STOC3,14)

S = 3, N = 14:

XAVG(STOC14,3)

That said, it would only be smoothed once, not twice. I would suspect a formula for a Double Smoothed Stochastic would more likely be (probably the second):

S = 14, N = 3:

.133453582702488 * (XAVG(STOC3,14) + 13 / 15 * (XAVG(STOC3.1.1,14) + 13 / 15 * (XAVG(STOC3.1.2,14) + 13 / 15 * (XAVG(STOC3.1.3,14) + 13 / 15 * (XAVG(STOC3.1.4,14) + 13 / 15 * (XAVG(STOC3.1.5,14) + 13 / 15 * (XAVG(STOC3.1.6,14) + 13 / 15 * (XAVG(STOC3.1.7,14) + 13 / 15 * (XAVG(STOC3.1.8,14) + 13 / 15 * (XAVG(STOC3.1.9,14) + 13 / 15 * (XAVG(STOC3.1.10,14) + 13 / 15 * (XAVG(STOC3.1.11,14) + 13 / 15 * (XAVG(STOC3.1.12,14) + 13 / 15 * (XAVG(STOC3.1.13,14) + 13 / 15 * (XAVG(STOC3.1.14,14) + 13 / 15 * (XAVG(STOC3.1.15,14) + 13 / 15 * (XAVG(STOC3.1.16,14) + 13 / 15 * (XAVG(STOC3.1.17,14) + 13 / 15 * (XAVG(STOC3.1.18,14) + 13 / 15 * (XAVG(STOC3.1.19,14) + 13 / 15 * (XAVG(STOC3.1.20,14) + 13 / 15 * (XAVG(STOC3.1.21,14) + 13 / 15 * (XAVG(STOC3.1.22,14) + 13 / 15 * (XAVG(STOC3.1.23,14) + 13 / 15 * (XAVG(STOC3.1.24,14) + 13 / 15 * (XAVG(STOC3.1.25,14) + 13 / 15 * (XAVG(STOC3.1.26,14) + 13 / 15 * (XAVG(STOC3.1.27,14) + 13 / 15 * (XAVG(STOC3.1.28,14) + 13 / 15 * (XAVG(STOC3.1.29,14) + 13 / 15 * (XAVG(STOC3.1.30,14) + 13 / 15 * (XAVG(STOC3.1.31,14) + 13 / 15 * (XAVG(STOC3.1.32,14) + 13 / 15 * (XAVG(STOC3.1.33,14) + 13 / 15 * (XAVG(STOC3.1.34,14) + 13 / 15 * (XAVG(STOC3.1.35,14) + 13 / 15 * (XAVG(STOC3.1.36,14) + 13 / 15 * (XAVG(STOC3.1.37,14) + 13 / 15 * (XAVG(STOC3.1.38,14) + 13 / 15 * (XAVG(STOC3.1.39,14) + 13 / 15 * (XAVG(STOC3.1.40,14) + 13 / 15 * (XAVG(STOC3.1.41,14) + 13 / 15 * (XAVG(STOC3.1.42,14) + 13 / 15 * (XAVG(STOC3.1.43,14) + 13 / 15 * (XAVG(STOC3.1.44,14) + 13 / 15 * (XAVG(STOC3.1.45,14) + 13 / 15 * (XAVG(STOC3.1.46,14) + 13 / 15 * (XAVG(STOC3.1.47,14) + 13 / 15 * (XAVG(STOC3.1.48,14))))))))))))))))))))))))))))))))))))))))))))))))))

S = 3, N = 14:

.500488758553275 * (XAVG(STOC14,3) + .5 * (XAVG(STOC14.1.1,3) + .5 * (XAVG(STOC14.1.2,3) + .5 * (XAVG(STOC14.1.3,3) + .5 * (XAVG(STOC14.1.4,3) + .5 * (XAVG(STOC14.1.5,3) + .5 * (XAVG(STOC14.1.6,3) + .5 * (XAVG(STOC14.1.7,3) + .5 * (XAVG(STOC14.1.8,3) + .5 * (XAVG(STOC14.1.9,3)))))))))))

 Thanks Bruce
The period is 14 and the smoothing is 3.

 You're welcome. I thought it was most likely that S = 3 and N = 14.

 To plot this on your chart just use a regular stochastics with a period of 14 and an exponential smoothing of 3.
