Order value and volume attributes

[sli-tao]

Taoshi Pull Request

Description

Fix bug to use currency conversion rate at order processed_ms time instead of current time.
Add order value and volume attributes. Orders must be specified using one of either leverage, value, and volume, and the other two will be derived. Pnl calculations will now use the order volume.

TODO:

• backfill value and volume for old orders
• need to track cost of open positions
