Backtesting data

Backtesting data files are sqlite database files. When using the regular data collector, these files contain every historical candles the requested exchange is willing to give. You can use a SQLite browser to explore these files.

Strategy tests

To quickly check tentacles strategy tests states or develop a new tentacles strategy test, change the following lines in octobot/tests/functional_tests/strategy_evaluators_tests/abstract_strategy_test.py:

def _handle_results(self, independent_backtesting, profitability):
    exchange_manager_ids = get_independent_backtesting_exchange_manager_ids(independent_backtesting)
    for exchange_manager in get_exchange_managers_from_exchange_ids(exchange_manager_ids):
        _, run_profitability, _, market_average_profitability, _ = get_profitability_stats(exchange_manager)
        actual = round(run_profitability, 3)
        # uncomment this print for building tests
        # print(f"results: rounded run profitability {actual} market profitability: {market_average_profitability}"
        #       f" expected: {profitability} [result: {actual ==  profitability}]")
        assert actual == profitability

into

def _handle_results(self, independent_backtesting, profitability):
    exchange_manager_ids = get_independent_backtesting_exchange_manager_ids(independent_backtesting)
    for exchange_manager in get_exchange_managers_from_exchange_ids(exchange_manager_ids):
        _, run_profitability, _, market_average_profitability, _ = get_profitability_stats(exchange_manager)
        actual = round(run_profitability, 3)
        # uncomment this print for building tests
        print(f"results: rounded run profitability {actual} market profitability: {market_average_profitability}"
              f" expected: {profitability} [result: {actual ==  profitability}]")
        # assert actual == profitability

This will not stop tests on failure and display the current tests results as well as expected values.
