How do I retrieve portfolio data for 5 days?

I’m using the /v2/account/portfolio/history endpoint with these parameters:
timeframe: 1D
period: 5D
date_end:2020-06-15

But i’m only getting 3 days of results and I know its because of the weekend. Is there another parameter that I can pass to ignore weekends? What can I do to get 5 days worth of data?
