Short-trades need to be supported by your exchange and market configuration!
Please make sure to set [`can_short`]() appropriately on your strategy if you intend to short.

!!! Note
`enter_long` column must be set, even when your strategy is a shorting-only strategy. On other hand, enter_short is an optional column and don't need to be set if the strategy is a long-only strategy

!!! Note
Buying requires sellers to buy from - therefore volume needs to be > 0 (`dataframe['volume'] > 0`) to make sure that the bot does not buy/sell in no-activity periods.
