Description

Expected Behavior

We don't see equity curve jumps due to unrealized profit that aren't real (e.g.: huge bid/ask when the market is closed)

Actual Behavior

Potential Solution

When the market is closed or the bid/price/ask spread is "suspicious" in live mode, use the price instead of the bid or ask.

Research direction

Start by reproducing the equity-curve jump described in the issue, focusing on unrealized profit during market-closed periods and suspicious bid/price/ask spreads in live mode. Trace where those values are selected and verify that the resulting equity curve uses the price instead when the bid or ask is unreliable.
