Equity decreased even though no order completed

I’ve just stated with paper trading using simple long short algorithm.
I figured that no trade took place since when I look at paper overview ->Order History I see that all orders are CANCELLED or PENDING, but when I look at the equity graph I see increase and decrease.
Could you help me figure out this behavior?

  1. How can I see the cash equity and securities equity separately?
  2. How can I see how each order affected the cash equity?

Thank you so much for helping a newB!

hope that helps you out
