How to find DPI?

Excuse me, could you please elaborate on how one might go about finding the DPI, or Depth Per Impact, in the realm of cryptocurrency and finance? I understand it's a metric used to measure the effectiveness of a trade or investment, but I'm a bit unsure of the specific steps or methods employed to calculate or determine this value. Is there a specific formula or tool that's commonly used? Additionally, are there any factors that need to be considered when interpreting the DPI, such as market conditions or the type of asset being traded? Thank you for your assistance.
