TL;DR: Use CoinTracking's validation tools to fix incorrect balances, identify missing or duplicate transactions, and understand tax warnings. Key steps include comparing balances using the Live API Data and Balance by Exchange pages, running reports like Validate Transactions, and reviewing the Transaction Flow Chart. Special care should be taken with FIAT tracking, depot separation, API re-syncing, and newly imported data, since missing or incorrect data directly affects the cost basis (and therefore the gains/losses) in your tax report.
Live API Data and Balance by Exchange
To verify your holdings:
Use the Live API Data page (if available) to see real-time balances from your exchanges or wallets.
Match these with calculated totals from the Balance by Exchange report.
Investigate and fix discrepancies exchange by exchange.
Manual Balances
If "manual balance" appears on the API Live Data page, some transactions are missing an exchange name. Go to the Transactions page, sort by the Exchange column, and fill in the missing fields.
Why do my corrections disappear after the next sync?
If you manually correct or complete transactions that originally came in through an API connection, those fixes can be overwritten the next time the API syncs. To avoid losing your corrections:
Set up your API connections so that already-corrected data is not re-imported or overwritten on the next synchronization (for example, by adjusting the sync start date or excluding already-fixed transactions where the exchange/API settings allow it).
Re-check your fixes after every sync until you're sure the connection is stable and no longer overwrites edited entries.
Validation Tools & Reports
1. Validate Transactions Report
This identifies faulty entries (e.g. typos, negative values). Expand each error row with "+" and follow the instructions to fix. Lines marked as "notice" are for informational purposes only.
2. Duplicate Transactions Report
Shows entries with identical transaction IDs (via exchange). To avoid errors:
Check the Trade List (Full View).
Add the Transaction ID column via "Manage Columns".
Delete duplicates and create a backup beforehand.
3. Missing Transactions Report
Displays unmatched transfers:
Transfers must consist of one withdrawal and one deposit.
White rows indicate unmatched entries due to time gaps or incorrect fees.
Add comments to unmatched entries you've already reviewed.
4. Transaction Flow Chart
Use this report when tax warnings persist:
Filter by coin and date to find negative purchase pools.
Identify where sale transactions exceed available coin amounts.
Investigate mismatches between manually added and imported data.
Why do these warnings matter for my tax report?
Negative purchase pools and unmatched transactions usually mean that the cost basis for one or more coins is missing or incorrect. Since the cost basis is the basis for calculating gains and losses, any error here directly affects the profit/loss figures in your tax report. Resolving these warnings before generating or filing your tax report helps ensure the calculated gains/losses are accurate.

Negative FIAT Values
These are usually not a problem. CoinTracking recommends not tracking FIAT deposits/withdrawals unless absolutely necessary:
Disable FIAT sync in your API settings.
Or enter them manually if needed.

Special Case: Depot Separation
Warnings may appear only when Depot Separation is enabled:
Causes include withdrawals without prior matching deposits.
Use the Flow Chart report (by tax year).
Filter by "warning" or use semicolons (;) to combine search terms like "ETH;warning".
Trade List & Report Creator
Use the Trade List (Full View) to:
See import sources via the "Imported From" column.
Sort by Add Date to review recent imports.
Use filters and search to isolate issues.
Export results in PDF, CSV, or Excel formats.
To edit/delete, open the Transactions page in a separate tab.
Still Seeing Errors?
If issues persist:
Open a support ticket.
Include:
Coin name
Exchange
Time period
Affected account or tax report number
A helpful screenshot
Focus on the largest or most obvious discrepancy when contacting support for faster resolution.
Can CoinTracking manually check my account for me?
If you'd rather not go through all imported and manual transactions yourself, you can request a Full Service Account Review. As part of this service, imported and manually entered transactions are manually checked and validated to help identify and resolve the underlying issues.
Summary
To validate your CoinTracking account:
Check balances using Live API Data and Balance by Exchange
Use validation reports: Validate Transactions, Duplicate Transactions, and Missing Transactions
Investigate warnings with the Flow Chart and Trade List reports, keeping in mind that unresolved warnings often point to missing/incorrect cost basis affecting your tax report
Set up API connections carefully so manual corrections aren't overwritten on the next sync
Manage FIAT handling and depot separation carefully
Contact support with detailed examples if problems persist, or request a Full Service Account Review for a manual check of your transactions
