目前是java實現 使用在MPAndroid上面，其他語言和圖表工具類比過去，可以然後將X,Y賦值過去
使用需知 chart_base_entity所有的類是你選用圖表時候對應的數據 需要去掉目前支持如下指標(多週期，及其他算法參數)
- EMA
- BOLL
- CCI
- DMI
- KDJ
- MACD
- OBV
- RSI
- SAR
- VOL
- WR
已封裝爲工具類可按如下調用
-
使用方法
//注意事項 // 使用需知 chart_base_entity所有的類是你選用圖表時候對應的數據 需要去掉 //現在爲了和圖表隔離 提供單純的算法工具類 所以才提供了臨時的Entry Candle BarEntry等 ChartDataCalculateUtils calculateUtils = new ChartDataCalculateUtils("你的數據List<Candle>你根據你實際使用的圖表進行替換"); //部分指標需要選擇週期 如EMA7 EMA10 List<Integer> periods = Arrays.asList(7, 10); calculateUtils.getEMA() calculateUtils.getBollData() calculateUtils.getCCI() calculateUtils.getDMI() calculateUtils.getKDJ() calculateUtils.getMACD() calculateUtils.getOBV() calculateUtils.getRSI() calculateUtils.getSARLineDatas() calculateUtils.getVol() calculateUtils.getWR() -
