Broker Sandbox account: Orders and Positions out of sync, Equity and portfolio history wrong data

**Describe the bug**

1. trailing stop filled but positions are still active , even after a month (critical)

- 452a1a83-db6d-4b50-bfbf-355735ecf86e ( IREN)
- 69f28e40-e241-47d2-a83f-b7bfe9f94570 ( LPTH)

2. sudden random bump of portfolio equity historical performance 2x of that time portfolio value and then next day its gone. it wasnt any cash transfer or anything , just directly on sandbox accounts .

**To Reproduce**
- not sure , it was unexpected and random

Start by reviewing the sandbox account records associated with the two supplied position IDs, comparing filled trailing-stop orders with their positions. Then inspect the equity and portfolio-history data around the reported unexplained bump. Done means the order, position, equity, and history values are consistent, with a reproducible test or diagnostic for both reported symptoms.
