Fix Fidelity Balance History Imports in Monarch Money (No Duplicate Date Errors)

Why This Breaks in Monarch Money:

When backfilling Fidelity brokerage or CMA history into Monarch, having multiple dividend reinvestments or trades on the same day causes Monarch’s balance importer to reject the entire file with "duplicate dates found in csv file."

How the Local Parser Fixes It:

Aggregates all same-day transactions and outputs a strictly deduplicated 2-column Date,Balance CSV with exactly one closing balance snapshot per calendar day.

3-Step Workflow: 1. Drop your Fidelity statement PDF (or CSV) into Step 1 above.2. Export the deduplicated Balance History CSV.3. In Monarch Web, open your Fidelity account -> Edit -> Import balance history.
