Volume Weighted Moving Average (VWMA)

get_vwma(quotes, lookback_periods)

Parameters

name	type	notes
`quotes`	Iterable[Quote]	Iterable(such as list or an object having `__iter__()`) of the Quote class or its sub-class. • Need help with pandas.DataFrame?
`lookback_periods`	int	Number of periods (`N`) in the moving average. Must be greater than 0.

Historical quotes requirements

You must have at least N periods of quotes to cover the warmup periods.

quotes is an Iterable[Quote] collection of historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Return

VWMAResults[VWMAResult]

This method returns a time series of all available indicator values for the quotes provided.
VWMAResults is just a list of VWMAResult.
It always returns the same number of elements as there are in the historical quotes.
It does not return a single incremental indicator value.
The first N-1 periods will have None values for Vwma since there’s not enough data to calculate.

# Calculate 10-period VWMA
results = indicators.get_vwma(quotes, 10)
