Excel as a bridge

Hi guys,

I have an excel question. So I’m using excel as a bridge between python and my trading platform ninjatrader. I’m getting values from another data source and processing those values in python and then sending those values to a file in excel (file 1). Then, I have another file (file 2) that is pulling the data from from file 1 (vlookups) and then sending it to ninjatrader.

Python cannot write to an excel file that is open. So file 1 has to be closed when python is saving the data to it.

I cannot send data from python directly to ninjatrader.

Problem: python is constantly updating file 1 every 20 minutes without opening the file. File 2 is open and doing vlookups in file1. But because file1 is closed the values don’t update automatically. I can’t have file 1 open bc python can’t write to excel if it’s open.

Is there a way to update my vlookups in file2 without having file1 open... and do this real time? In my data connection I have checked automatically update ... but it doesn’t.

Any ideas? Thanks.

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
