Golang stock market technical analysis library
GoTrade is in early design and development
Below is a look at the basic API so far
csvFeed := feeds.NewCSVFileFeedWithDOHLCVFormat("../github.com/thetruetrade/gotrade/testdata/JSETOPI.2013.data", feeds.DashedYearDayMonthDateParserForLocation(time.Local)) priceStream := gotrade.NewDailyDOHLCVStream() sma, _ := indicators.NewSMAForStream(priceStream, 20, gotrade.UseClosePrice) ema, _ := indicators.NewEMAForStream(priceStream, 20, gotrade.UseClosePrice) bb, _ := indicators.NewBollingerBandsForStream(priceStream, 20, gotrade.UseClosePrice) csvFeed.FillDOHLCVStream(priceStream) fmt.Println("price stream has data of length: ", len(priceStream.Data)) fmt.Println("price stream has min date: ", priceStream.MinDate()) fmt.Println("price stream has max date: ", priceStream.MaxDate()) fmt.Println("sma has data of length: ", len(sma.Data)) fmt.Println("sma is valid from price stream bar number: ", sma.ValidFromBar()) fmt.Println("sma max: ", sma.MaxValue(), " sma min: ", sma.MinValue()) fmt.Println("ema has data of length: ", len(ema.Data)) fmt.Println("ema is valid from price stream bar number: ", ema.ValidFromBar()) fmt.Println("ema max: ", ema.MaxValue(), " ema min: ", ema.MinValue()) fmt.Println("bollinger bands has data of length: ", len(bb.Data)) fmt.Println("bollinger bands is valid from price stream bar number: ", bb.ValidFromBar()) fmt.Println("bollinger bands max: ", bb.MaxValue(), " sma min: ", bb.MinValue())
Tasks for the near future include:
- Complete a basic set of indicators
- Add point and figure price streams
- Basic pattern matching
- Candlesticks
- Point and figure patterns
- Visualisation in gotrade-plot
- Operator support like Crosses etc.
- Script engine in gotrade-script
