Expect mrtools teacher to add candles option to this great indicator:
As shown below:
1. If the lowest price of candles is greater than the signal line (ie green + thick yellow line), the candles are drawn in green;
2. If the highest price of candles is less than the signal line (ie green + thick yellow line), the candles are drawn in red;
3. If the candles cross the signal line (that is, the thick green + yellow line), the candles are drawn in gray.
