How do I record a coin swap in Delta? Here is what we recommend you do to reconcile data in your portfolio with any swaps, such as VEN to VET.
Simple sell for 0 value
SELL the old coin (VEN) at a price of 0.
Enter a BUY of the new coin (VET) at a price of 0.
This method is simplest and recommended if you are not concerned with keeping the same profit & loss values for VET that you had for VEN and registering a realized loss for VEN and starting VET with a cost basis of zero.
Sell for the current price
Enter a SELL of all your VEN for the current market price (or price at the time of swap)
Enter a BUY of VET at the current market price or price (or price at the time of swap)
Essentially, this pair of buy and sell behaves as a VET / VEN buy. This method is recommended if, from your perspective, the swap can be recorded as an indirect VET / VEN trade.
If an asset has changed name, shortcode or exchanges.
The above method will not bring your whole history across. A work-around is to export your history to CSV and modify the CSV to only have the relevant transactions and change the Name / Shortcode and / or Exchange. Then you can import the CSV. We do recommend you import into a new empty portfolio for testing purposes to make sure the import worked as expected.
