Based on your feedback we've made improvements to order history on Bittrex.com and Bittrex International.
Customers can now download their full and complete order history. Visit the Orders page and select Download History to download. There you may select which year to download. The order history will be downloaded as a .csv file.
Prior to this change only very recent history was available for download and it did not include delisted coins/tokens. Now the Download History and Recent Orders section of the Orders page will now present all orders from both listed and delisted coins/tokens.
