problem is that usually signals come earlier than shown in the chart. Still the system would still work if you get an entry/exit price close to BBBot or BBTop. Trading this system in the hourly time frame will still give a good result for ES mini futures when you take into account a “slippage” from BBBot and BBTop of 3 ticks. For oil 8 ticks is allowed.

Question is can you get anywhere near that in reality.
