## Add more Indicator
As you have seen, buy and sell strategies need indicators. You can add
more indicators by extending the list contained in
the method `populate_indicators()` from your strategy file.
As you have seen, buy and sell strategies need indicators. You can add more indicators by extending the list contained in the method `advise_indicators()` from your strategy file.
You should only add the indicators used in either `advise_buy()`, `advise_sell()`, or to populate another indicator, otherwise performance may suffer.
Sample:
```python
def populate_indicators(dataframe: DataFrame) -> DataFrame:
def advise_indicators(self, dataframe: DataFrame, pair: str) -> DataFrame:
"""
Adds several different TA indicators to the given DataFrame
