Ledger of Alpha supports native CSV import for a set of US-market brokers, a universal column mapper for everything else, and automatic sync through a broker-connection service.
Native CSV import
- Interactive Brokers (transactions & Flex queries)
- TradeStation (order history, tax center, transactions)
- NinjaTrader
The public integrations page lists the current set with per-broker notes.
Any other broker
Export a CSV and use column mapping — it covers brokers without a native parser.
Automatic sync
Many US brokers (including Interactive Brokers) can be connected for automatic sync on Essential and Pro. Available brokerages depend on the connection service.
