It's important to always return the dataframe without removing/modifying the columns `"open", "high", "low", "close", "volume"`, otherwise these fields would contain something unexpected.
This method will also define a new column, `"enter_long"`, which needs to contain 1 for entries, and 0 for "no action".

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.

`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

dataframe.loc[: ,'enter_long'] = 0
dataframe.loc[
(
(qtpylib.crossed_below(dataframe['rsi'], 70)) & # Signal: RSI crosses below 70
(dataframe['tema'] > dataframe['bb_middleband']) & # Guard
(dataframe['tema'] < dataframe['tema'].shift(1)) & # Guard
(dataframe['volume'] > 0) # Make sure Volume is not 0
),
['enter_short', 'enter_tag']] = (1, 'rsi_cross')
return dataframe
```
return dataframe

!!! 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.
