// C# usage syntax
IReadOnlyList<CandleResult> results =
  bars.ToMarubozu(minBodyPercent);

Parameters ​

paramdescription
minBodyPercent
double		Optional. Minimum body size as a percent of total candle size. Example: 85% would be entered as 85 (not 0.85). Must be between 80 and 100, if specified. Default is 95 (95%).

Historical price bars requirements ​

You must have at least one historical bar; however, more is typically provided since this is a chartable candlestick pattern.

bars is a collection of generic TBar historical price bars. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response ​

csharp
IReadOnlyList<CandleResult>
  • This method returns a time series of all available indicator values for the bars provided.
  • It always returns the same number of elements as there are in the historical price bars.
  • It does not return a single incremental indicator value.
  • The candlestick pattern is indicated on dates where Match is Match.BullSignal or Match.BearSignal.
  • Price is Close price; however, all OHLCV elements are included in CandleProperties.
  • There is no intrinsic basis or confirmation signal provided for this pattern.

Match ​

When a candlestick pattern is recognized, it produces a matching signal. In some cases, an intrinsic confirmation is also available after the signal. In cases where previous bars were used to identify a pattern, they are indicated as the basis for the signal. This enum can also be referenced as an int value. Documentation for each candlestick pattern will indicate whether confirmation and/or basis information is produced.

enum / valuedescription
Match.BullConfirmed
200		Confirmation of a prior bull signal
Match.BullSignal
100		Bullish signal
Match.BullBasis
10		Bars supporting a bullish signal
Match.Neutral
1		Signal for non-directional patterns
Match.None
0		No match
Match.BearBasis
-10		Bars supporting a bearish signal
Match.BearSignal
-100		Bearish signal
Match.BearConfirmed
-200		Confirmation of a prior bear signal

Streaming ​

Use the buffer-style List<T> when you need incremental calculations without a hub:

csharp
MarubozuList marubozuList = new(minBodyPercent);

// call from your WebSocket or SSE message handler
void OnBarReceived(IBar bar) => marubozuList.Add(bar);

// based on `ICollection<CandleResult>`; fills as the handler runs
IReadOnlyList<CandleResult> results = marubozuList;

Subscribe to a BarHub for advanced streaming scenarios:

csharp
BarHub barHub = new();
MarubozuHub observer = barHub.ToMarubozuHub(minBodyPercent);

// call from your WebSocket or SSE message handler
void OnBarReceived(IBar bar) => barHub.Add(bar);

// results fill as the handler runs
IReadOnlyList<CandleResult> results = observer.Results;

See Buffer lists and Stream hubs for full usage guides.
