Overview
Klinger Oscillator calculates signed volume by determining whether the typical price (HLC3) increased or decreased relative to the previous bar. The main oscillator line represents the difference between a 34-period and 55-period exponential moving average of signed volume, plotted alongside a 13-period EMA signal line in a separate pane to help identify volume trends and momentum crossovers.

Calculates the standard Money Flow Index (MFI) oscillator alongside an exponential moving average signal line in a separate pane. The script visually highlights trend conditions through dynamic ribbon filling, optional difference histogram bars, and overbought
This indicator measures directional momentum by evaluating candlestick body proportions and volume over a user-defined lookback window. It computes the ratio of candle body to total range, weights the cumulative value by volume and absolute body size, and dete
This indicator builds an aggregate oscillator in a separate pane. It scales open, high, low, close, and volume into a 0 to 1 range, then averages scaled readings from MACD, a MACD histogram, RSI, stochastic, CCI, momentum, OBV, a directional index, volume-weig
This indicator calculates the Bill Williams Market Facilitation Index as the high-low range divided by volume, or zero when volume is zero. It compares the index and volume with the previous bar and assigns one of four zones: green for both rising, fade for bo
PPO ATR Bands plots a percentage price oscillator in a separate pane. It compares a Hull average of typical price with a volume-weighted exponential average of Parabolic SAR, then scales three true-range bands around the slow average into matching oscillator l
Calculates the Chaikin Oscillator by taking the difference between a fast exponential moving average and a slow exponential moving average of the Accumulation/Distribution line. It plots the resulting line in a separate pane alongside a dashed zero reference l
