Describe the problem:

I bought 7619,847 DOT at 6,59€ on February 8 2024.
I sold 566,789 DOT at 7,07€ on February 14 2024 and the remaining (7053,058) at 3,99€. See attached Coinbase order screenshot.

My initial cost per unit should be 6,59€.
Koinly calculates my purchase cost per unit at 6,68€ and 3,48€. See Koinly screenshots

Hi @Ludovic_Levivier

This depends on many factors such as your cost basis and cost tracking methods, missing purchase history errors in the account, unaccounted for transfers,…
