Is the data already being saved to the spreadsheet somewhere? And, is that saved data what you want to use to make the chart?

The data is not saving.  The data is the trading price of a particular share which is changing every second.

What is updating cell A1 right now? Do you have a macro that does this? Because then you can just add a few lines of code to that existing macro to save the data and then the chart can probably be created using some simple dynamic formulas.

Thank you for responding.  I am getting data from an online trading software.  The macro showing is =RTD("nest.scriprtd",,"nse_fo|NIFTY16OCT8800PE","LTP") .  Here Nest is the trading platform of Nifty (Indian stock exchange) and LTP is the last trading price..  i need the high/low of this LTP or the line chart.

Based on your question, you need to have a macro that runs every second (which is not great by the way because it can "freeze" the rest of Excel if you want to use it).

Use this macro as the template for running every second:

Sub timer_copy_data()

    interval = Now + TimeValue("00:00:01")

    'Code to run every second
    Cells(Range("A" & Rows.Count).End(xlUp).Row + 1, 1).Value = Cells(1, 1).Value

    Application.OnTime interval, "timer_copy_data"

End Sub

This should copy the data into the next empty row in column A every second once you start the macro.

Update

For the chart, follow this tutorial (one of ours) to make a dynamic chart.
