[µo°Ý] How to scrape this website dynamic data from Javascript with VBA?

Website: https://www.hangseng.com/en-hk/personal/insurance-mpf/e-mpf/fund-price-performance/

Targets of automate data scraping: fund price as highlighted in the below figure



Tools: VBA(Excel), Chrome driven by Selenium

The code started as below:
  1. Chrome.ExecuteScript "window.open('https://www.hangseng.com/en-hk/e-services/e-mpf/fund-price- performance/price/','_blank');"

  2. Chrome.SwitchToNextWindow

  3. Chrome.FindElementByXPath("//a[text()='Acknowledge']").Click
½Æ»s¥N½X
Then I have no further idea to retrieve those specified data. Please provide help. Thanks a lot!

Sub test2()
Set chrome = CreateObject("selenium.chromedriver")
chrome.get "https://www.hangseng.com/en-hk/personal/insurance-mpf/e-mpf/fund-price-performance/"
chrome.Wait 1000

Set A_s = chrome.FindElementsBytag("a")
    For i = 1100 To A_s.Count
     If A_s(i).Text = "Acknowledge" Then A_s(i).Click: Exit For
    Next


ReDim ar(1 To 1000, 1 To 1)
Set td_s = chrome.FindElementsBytag("td")
    For Each Z In td_s
        If Z.attribute("headers") = "price_header1" Then w = w + 1: ar(w, 1) = Z.Text
    Next
   
Cells.ClearContents
Cells(1, 1).Resize(w, 1) = ar
End Sub

  The code is very simple , but very productive!
There are also two questions:
1)
  1. Set A_s = chrome.FindElementsBytag("a")
  2.     For i = 1100 To A_s.Count
½Æ»s¥N½X
Only 139 "<a" tag can be searched in the website source code, what is the meaning of 1100 here?

2)  for another website http://www.aastocks.com/tc/stocks/quote/detailchart.aspx?symbol=110000
It is possible to extract the highlighted RSI data ?


Thank you very much!
