Strategy conceptualisation of signals

The strategy below is simply to understand the signal implementation, and not to trade live...

from pandas import DataFrame
from freqtrade.strategy.interface import IStrategy

class ToggleHourlyDate(IStrategy):
    """
        Enter and exit every hour on the 1 minute timeframe using the 'date' column.
    """
    INTERFACE_VERSION: int = 3
    minimal_roi = {"0": 10}   # Close immediately at 1000% ROI.
    stoploss = -1             # SL at -100%.

    def populate_indicators(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
        return dataframe

    def populate_entry_trend(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
        dataframe.loc[(dataframe['date'].dt.hour % 2 == 0) &
                      (dataframe['date'].dt.minute == 0), 'enter_long'] = 1
        return dataframe

    def populate_exit_trend(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
        dataframe.loc[(dataframe['date'].dt.hour % 2 != 0) &
                      (dataframe['date'].dt.minute == 0), 'exit_long'] = 1
        return dataframe

Explanation of the code:

dataframe.loc[(dataframe['date'].dt.hour % 2 == 0) & (dataframe['date'].dt.minute == 0), 'enter_long'] = 1

This line uses the .loc method of the dataframe to select only the rows where the hour of the date column is even (dataframe['date'].dt.hour % 2 == 0) and the minute of the date column is zero (dataframe['date'].dt.minute == 0). Then it sets the value of the enter_long column in these selected rows to 1.

`dataframe.loc[(dataframe['date'].dt.hour % 2 != 0) & (dataframe['date'].dt.minute == 0), 'exit_long'] = 1

This line is similar to the previous one, but it selects the rows where the hour of the date column is odd (dataframe['date'].dt.hour % 2 != 0) and the minute of the date column is zero (dataframe['date'].dt.minute == 0), and sets the value of the exit_long column in these selected rows to 1.

So, every time the hour is even (e.g. 10:00, 12:00, 14:00), the entry is set to 1 for the row with the minute of the date equal to 0 (e.g. 10:00), and every time the hour is odd (e.g. 11:00, 13:00, 15:00), the exit is set to 1 for the row with the minute of the date equal to 0 (e.g. 11:00). This way, the enter_long and exit_long signals are generated only once per hour.
