In the “TCI”, a short “SMA” is divided by a longer “SMA”, regardless of whether it is “simple”, “exponential” or “weighted”, whereby the quotient is usually multiplied by 100 for better representation. The result is an oscillator with the center line at 100. An oscillator value above the center line shows that the short "SMA" is above the longer "SMA", similarly a value below the center line shows that the short "SMA" is below the longer " SMAs” noted.
Calculation: Two “moving averages” are constructed, with the shorter “SMA” divided by the longer “SMA”. The result is multiplied by a factor of 100.
Formula: TCI = (MAx / MAy ) * 100
MAx = “Moving Average” shorter period of time MAy = “Moving Average” longer period
