get_recent_trades crashes due to new column

[Monolite]

Apparently, kraken api has released a new version in which a new column has appeared, leading to api failure when setting trades.columns. After adding a new column name, api works properly, but can't tell what data was added.

Any suggestion on new column's naming? Looks like a consecutive value...
