Use open price to calculate Bollinger Bands

[pooyan-fekrati]

Hi all,

Ia there a way to use open price instead of close price when using the GetBollingerBands method?

It's not part of the standard parameter options like we do for SMA and EMA, but you can still do it by converting your quote history to replace Close price with Open price, then run it through.

var altQuotes = quotes
    .Select(x => new Quote
    {
        Date = x.Date,
        Close = x.Open
    });

var results = altQuotes.GetBollingerBands(..);

Starting with v2, you can now choose any price element or candle variant to generate Bollinger Bands. Here's an example of the syntax:

// example
var results = quotes
    .Use(CandlePart.Open)
    .GetBollingerBands(..);
