TA-Lib candlestick not detected?

[jimmyhou852]

Hi guys,

I am trying to see if TA-Lib detects the "Mat Hold" or "Rising / Falling Three Methods" on the ticker: 1611.HK on November 15 2020 (weekly chart, closing prices). Though I can see it clearly on the chart, TA-Lib didn't detect the pattern when I retrieve weekly prices from yfinance (though the date seems to have been shifted by 1 for weekly interval).

Any insight as to the pattern wasn't detected but is clearly there?
