Track slippage over each completed trade

[tiagosiebler]

Just a note to enhance the tracking in zenbot, so you can analyse the average slippage per trade over time. Knowing that from live tests, means you'll have more tools for an accurate sim. The default 0.045 slippage for the sim can be misleading for estimating the performance of a new strategy.

Hi @tiagosiebler I'm about to do a PR that exposes a REST API for zenbot. From that you can read all the live data that zenbot has, including all trades and the slippages it has.
Hopefully that will also solve this issue.

Wicked! That should hit the nail on the head! Thanks @abduegal
