CoinLedger only needs "Read" or "View" access to import your trade history. This permission protects your accounts. Learn more about API access in this article here.
Note: NDAX API only returns up to 3 months worth of trades. If you traded on NDAX for longer than 3 months it's recommended to switch to file import to capture the full range of your crypto transaction history.
