The strategy looked good, but not anymore after a 20% drawdown within a few days in December. And it is still unclear whether the drawdown will become even larger. A 7-10% account loss in one day is possible. This happened 3 times in December. Once the daily loss was made up for by a profit a few days later. To me, this strategy takes unacceptable daily risks, which is clearly evident in December. After this realization, I definitely no longer use the strategy.
