Problem:

Pamela was rebalancing just fine, however, after doing it for maybe 8 or 9 times, it suddenly stopped.

Steps to replicate:

1. Start a test rebalancing with pamela
2. Run it for a few times over.

Expected: It should continue until /halt command is triggered
Current: It is stopping by itself

Kick off Checklist:

• Check Pamela.Trader.rebalance function, it may be failing to pattern match on the with.
• Consider refactoring the with to other files, should help catch the bug easier
