A useful feature where the user specifies the quantity to take in an orderbook and callback returns the average price paid for that lot size. For example if the offers in the order book for BTC-USD was the following:

Price | size
11,000 | 1
10,500 | 1
10,000 | 1

If the user specified quantity 3, the callback would return 10,500.

To implement Bolinger Bands, we need to implement a new Struct similar to EMA: https://github.com/rodrigo-brito/ninjabot/blob/516e75064107daf73495bf1d091b5dc1cba18c09/plot/indicator/ema.go

The struct must implement the following interface:

type Indicator interface {
	Name() string
	Overlay() bool
	Metrics() []IndicatorMetric
	Load(dataframe *model.Dataframe)
}
