Note - CryptoTrader.Tax does not currently support the taxation treatment of margin trades.

Update 7/27/2020 - Poloniex is closed to U.S. customers; however, you can still retrieve your complete Poloniex trade history file by logging into your account here:

Step 1:
Login To Your Poloniex Account

Step 2:
Select "My Trade History & Analysis" from the Orders drop down

Step 3:
Select "Export History"

Step 4:
Select the "Trade" option and export your trade history from ALL years of trading using Poloniex's date ranges. 

(You many have to export multiple files to capture all of your history. Please make sure dates do not overlap to avoid duplicate trades).

DO NOT open the file in Excel and "save as" a new file.  

It's important to upload the raw file that Poloniex exports straight from your "Downloads" folder. This avoids rounding errors and corrupting the file. If you need to edit your CSV, please use Google Sheets.

Step 5:
Navigate to the Poloniex tab on CryptoTrader.Tax and drag the file you just downloaded into the blue box.
