Syntax Format​

vidya(source, period)

Overview​

VIDYA (Variable Index Dynamic Average) is one of the more complex averages, where several factors are considered. This function is called dynamic because it adjusts its data based on the current volatility of an asset. Also, the responsiveness of the VIDYA is dynamic as well, as it is based on the CMO (Chande Momentum Oscillator).

Parameters​

ParameterTypePurpose
sourceseriesInput series, taken into calculation
periodnumericMoving Average period

Returns: series.

Example​

instrument { name = "Variable Index Dynamic Average", short_name = "VIDYA", overlay = true, icon="indicators:MA" }

period = input (9, "period", input.integer, 1)
source = input (1, "source", input.string_selection, inputs.titles_overlay)

input_group {
    "VIDYA Line",
    color = input { default = "#B42EFF", type = input.color },
    width = input { default = 1, type = input.line_width}
}

local sourceSeries = inputs [source]

plot (vidya (sourceSeries, period), "VIDYA", color, width)

Formula​

The formula for calculating VIDYA is:

The CMO is used to determine the factor, which is based on volatility of the chosen price series and period. This factor is used to adjust the results to dynamically changing volatility value.
