Parameter Description

DataSeries Typically the Close DataSeries reference

period2 EMA slow period used for the CPC indicator.
m Period for the piecewise EMA of cumulative price change from the slow/fast CPC EMA crossovers.
n Period used for noise calculation. Generally you should specify n >= m
c Correction factor for the signal (trend) to noise ratio.

Description

The Trend Noise Balance (B-indicator) from the April 2004 issue of Stocks & Commodities magazine determine trends "with a procedure that attempts to recognize, in a timely way, promising and nonpromising (sic) price trends within the extracted semicycles as well as estimate their strength".

Fluctuating between 0 and 100, TrendB measures the strength of a trend but not its direction. Its value goes to 0 whenever the CPC EMAs with period1 and period2 cross. Per the author, David Sepiashvili, readings can be interpreted as follows:
  • 50 - 65: weak trending
  • 65 - 80: moderate trending
  • above 80: strong trending
