How to make a range bar chart - vba

Question

Hey I'm new to forums and this is my first post. I am new to vba in excel, but have written thinkscript in ThinkorSwim.
If anyone is familiar with a range stock chart, thats what Im going after.
I found code for a line chart, and am using it, but it is based on where price is at any given time. I want to modify this line chart to only plot values when they are above or below a range so that it resembles a candlestick chart with no wicks. Once data enters that range, I only want it to update whenever a new high or low is made in that range. The ranges need to be preset (ex. 50 ticks) Once the range is exceeded, I want the data plotted in the next range up, and repeat the process. Time and dates should be ignored, and only plot based on price action.
Does anyone have any ideas?

Take your sheet of data and filter... example would be:
Columns("A:C").Sort key1:=Range("C2"), _
order1:=xlAscending, header:=xlYes
Sort info: https://msdn.microsoft.com/en-us/library/office/ff840646.aspx
You then can define to select your desired range. Assuming column A is x-axis and B is y-axis (where your parameters for modifying need to be assessed):
Dim High1 as integer
Dim Low1 as integer
High1 = Match(Max(B:B),B:B) 'This isn't tested, just an idea
Low1 = Match(Max(B:B)+50,B:B) 'Again, not tested
and using those defined parameters:
.Range(Cells(High1,1),Cells(Low1,2).Select
This should give an idea for High1/Low1, where you can work through how you want to define the row that the max value occurs.
You then CreateObject for the Chart you want, having selected the data range you are going to use.
