Seems like this pair wants to make one more push higher, in this case this pattern should work well.
If you backtest bats you'll find that 0,382-0,618 B-point ratio has 53% of success while 0,5-0,618 B-point ratio has 66%. Including 0,382-0,499 B-point ratio to your trading plan you are throwing 13% of profitability away. I respect Scott Carney as a founder of Bat and Harmonic trading but his ratios are not ideal. The research of advanced patterns made by T2 University allowed to optimize ratios to improve pattern's profitability. Tradeempowered and DCAST Capital use these ratios. Remember that before Scott Carney B-point ratio of 0,382-0,786 was thought to be a Gartley pattern. These ratios were introduced by Larry Pasavento. Time goes by and patterns are optimized. But I would strongly recommend you to do backtesting manually by yourself. Just backtest that kind of Bats that has 0,382-0,499XA B-point ratio and you'll find this kind has negative expectancy. That's why this specific kind of Bats lowers the general profitability of the pattern. Check these Rules of Engagement:
