Draw tendency lines based on given values from an excel file

Hello,

I need to import data from excel (resistance and support levels) to my chart.

Specifically, they should be all ploted as trend lines as shown in the example below:

• For each trend line, the start and finish Date will always be the same
• Date input in excel: dd/mm/yyyy
• I need to plot up to 500 trend lines specified in my excel spreadsheet
• All trendline visual parameters are not important, they can be all red and continuous lines
• After making this script/program, please tell me in wich format my excel file must be saved and in wich folder it must be placed
