Coinmarketcap Portfolio Tools for Correcting Records

Buy, Sell, and Transfer Records

The portfolio uses Buy, Sell, and Transfer entries to describe different changes in holdings. Buy records represent purchases, while Sell records represent sales. Transfer entries describe assets moving into or out of the tracked holdings. Choosing the appropriate type preserves the distinction between acquiring an asset through a purchase and recording an incoming movement.

Transaction history provides the detail behind the holding total. Editing an incorrect entry preserves the surrounding history; removing an unwanted entry addresses a record that should not exist. Removing an entire asset has a broader scope, so it is a poor substitute for correcting one mistaken transaction.

Which Portfolio Records Can You Edit?

Manual transaction records support corrections through the asset's transaction details, including changes to recorded quantities and purchase prices. The purchase form also includes the transaction date, time, fee, and an optional note. Review the existing entry before changing it, because an incorrect field and a missing transaction require different actions. The portfolio also supports adding and removing assets.

Keep the correction as narrow as the mistake. An accurate quantity should remain unchanged when only the purchase price needs correction. Likewise, a note explaining an unusual transaction should survive an unrelated date adjustment.

Purchase Price and Fees

A purchase record needs the actual price paid per unit, rather than the asset's price when you later enter the transaction. Separate that unit price from the total purchase amount. Copying a total into the unit-price field multiplies the purchase value again when the tracker applies the quantity.

For a straightforward purchase, quantity multiplied by unit price gives the purchase amount before fees. Adding a separately charged fee gives the total outlay when every monetary input uses the same currency. This arithmetic provides a reconciliation check; it does not establish the tracker's treatment of every profit calculation.

Fee treatment needs particular care. A receipt may show a total that already includes fees, or a fee charged in another asset. Adding the same charge twice overstates the outlay. Combining amounts in different currencies without conversion also produces a meaningless total. Preserve the receipt's denomination and distinguish the amount purchased from the amount ultimately received.

Dates and Transaction Order

The transaction date should describe when the purchase, sale, or transfer occurred, rather than when you repaired the portfolio entry. Historical records lose context when corrections replace event dates with today's date.

Keep the timestamp alongside its original time zone in your supporting records. Two displays can show different clock times for the same event. Before changing a date, determine whether the discrepancy concerns the event itself or its presentation. Preserve separate purchases when they occurred at different prices or times; combining them can remove detail needed to explain later differences.

Duplicate Entries and Missing Transactions

Duplicate entries repeat activity already represented in the portfolio, while missing entries leave genuine activity out. Similar amounts alone do not establish duplication. Repeated purchases can have matching quantities and prices, so compare dates and the underlying transaction records before removing anything.

A useful correction preserves every genuine event once. Reducing a valid purchase to compensate for a duplicate produces a plausible total with an inaccurate history. Increasing another purchase to conceal a missing entry creates the opposite problem. The holding total may agree temporarily, while purchase amounts and transaction dates remain wrong.

Why Is the Balance Still Different After an Edit?

A balance can remain different because market prices move, other transaction errors remain, or historical charts have not finished recalculating after an edit. The portfolio values holdings using quantities and current prices, so a changing monetary total alone does not show whether a saved correction succeeded.

Inspect the saved transaction fields separately from the live valuation. A purchase-price correction addresses acquisition information; it does not require the current quantity or market price to change. Compare quantities first when reconciling holdings. Then compare the valuation currency and observation time. While historical charts recalculate, check whether the original transaction already contains the correction before adding a replacement. Keeping both records can duplicate the same activity.

Synced Holdings and Manual Corrections

Synced portfolios obtain holdings through supported address or exchange connections, while manual portfolios rely on transaction details the user enters. Connection compatibility therefore matters before choosing how to maintain a record. A supported connection does not establish that every imported field offers the same editing controls as a manual entry.

For an imported mismatch, identify the connected account or address and the affected asset before adding compensating manual activity. Otherwise, a later sync could leave both the imported holding and its manual substitute in your tracking records. Keep any separate reconstruction clearly distinguished from the synced portfolio. A correction in a manual copy does not repair the external account's history.

Does Deleting a Record Reverse the Original Transaction?

Deleting a portfolio record removes tracking information; it does not reverse the purchase, sale, or transfer the entry describes. Manual portfolio entries do not execute asset transactions.

A mistaken entry belongs in the portfolio correction process. A problem with an actual trade or movement of funds belongs with the service or wallet involved in that event. Changing the displayed quantity cannot return funds, cancel an executed trade, or correct a destination address.

Records to Keep Before Removing an Asset

Keep an independent copy of useful transaction details before removing an asset or rebuilding its history. Preserve the asset identity, transaction type, quantity, price, date, fee denomination, and any explanatory notes. Trade receipts and transaction identifiers help distinguish the original event from a later tracking correction.

Do not treat deletion as a temporary hiding control. Without a retained copy, reconstructing the history may require finding every underlying record again. A screenshot can preserve visible fields, but it may omit transaction details outside the current view. Retain the information necessary to explain the entry, rather than only its displayed balance.

Finishing the Reconciliation

Reconciliation finishes when the corrected history explains the holdings within the portfolio's intended scope. Check that the saved entry describes the right asset and event, then compare its fields with the underlying record. Account for legitimate incoming and outgoing activity rather than forcing a total through an unrelated adjustment.

Preserve any unresolved difference explicitly. An unknown purchase price should not become a guessed price merely to produce a complete profit figure.

Continue manual entries when you can supply the transaction details, or use a compatible connection for supported holdings. Keep historical purchase evidence in either case; a current balance alone cannot explain what you paid.
