TA-Lib学习研究笔记（九）——Pattern Recognition （0）

1.Pattern Recognition Functions 形态识别

所有的形态函数，大部分可以在股票软件中找到，通过Python的talib实现形态识别，可以和股票软件对比一下。

看一下Pattern Recognition有多少函数：

for i in tlb.get_function_groups():print (i,len(tlb.get_function_groups()[i]))print (tlb.get_function_groups()[i])print ()

Pattern Recognition 61
[‘CDL2CROWS’, ‘CDL3BLACKCROWS’, ‘CDL3INSIDE’, ‘CDL3LINESTRIKE’, ‘CDL3OUTSIDE’, ‘CDL3STARSINSOUTH’, ‘CDL3WHITESOLDIERS’, ‘CDLABANDONEDBABY’, ‘CDLADVANCEBLOCK’, ‘CDLBELTHOLD’, ‘CDLBREAKAWAY’, ‘CDLCLOSINGMARUBOZU’, ‘CDLCONCEALBABYSWALL’, ‘CDLCOUNTERATTACK’, ‘CDLDARKCLOUDCOVER’, ‘CDLDOJI’, ‘CDLDOJISTAR’, ‘CDLDRAGONFLYDOJI’, ‘CDLENGULFING’, ‘CDLEVENINGDOJISTAR’, ‘CDLEVENINGSTAR’, ‘CDLGAPSIDESIDEWHITE’, ‘CDLGRAVESTONEDOJI’, ‘CDLHAMMER’, ‘CDLHANGINGMAN’, ‘CDLHARAMI’, ‘CDLHARAMICROSS’, ‘CDLHIGHWAVE’, ‘CDLHIKKAKE’, ‘CDLHIKKAKEMOD’, ‘CDLHOMINGPIGEON’, ‘CDLIDENTICAL3CROWS’, ‘CDLINNECK’, ‘CDLINVERTEDHAMMER’, ‘CDLKICKING’, ‘CDLKICKINGBYLENGTH’, ‘CDLLADDERBOTTOM’, ‘CDLLONGLEGGEDDOJI’, ‘CDLLONGLINE’, ‘CDLMARUBOZU’, ‘CDLMATCHINGLOW’, ‘CDLMATHOLD’, ‘CDLMORNINGDOJISTAR’, ‘CDLMORNINGSTAR’, ‘CDLONNECK’, ‘CDLPIERCING’, ‘CDLRICKSHAWMAN’, ‘CDLRISEFALL3METHODS’, ‘CDLSEPARATINGLINES’, ‘CDLSHOOTINGSTAR’, ‘CDLSHORTLINE’, ‘CDLSPINNINGTOP’, ‘CDLSTALLEDPATTERN’, ‘CDLSTICKSANDWICH’, ‘CDLTAKURI’, ‘CDLTASUKIGAP’, ‘CDLTHRUSTING’, ‘CDLTRISTAR’, ‘CDLUNIQUE3RIVER’, ‘CDLUPSIDEGAP2CROWS’, ‘CDLXSIDEGAP3METHODS’]

一共61个函数，数量大，逐一测试验证工作量不小，计划每个小节10个函数，循序渐进。

2. 数据环境准备

为了能清楚展示各类K线形态的效果，使用mplfinance 绘制蜡烛图。
数据周期选择从2000年到2022年，23年的数据，希望能够覆盖各类K线形态。
