Indicator Functions
Description
Keltner band (channel) bottom
Syntax
KBBot(len, atrs)
Parameters
len - lookback period
atrs - number of ATRs
Notes
It's not clear that there's a "standard" way to implement Keltner channels. The center line could be either a simple or an exponential average. The ATR might use a simple average, EMA, or Wilder's smoothing. This function is a shortcut for EMA(C, len) - atrs * EMA(TR, len).
This indicator supports one-pass calculation when used in the Data Section with a non-variable length.
