Each price level is configurable by percentage (from the high or low), name, and color.

Three price levels are plotted by default:
- Highest Price Level (100%) - The maximum traded price of an instrument over a specific period of time (red line on the above screenshot)
- Middle Price Level (50%) - The average of the maximum and minimum traded price over a specific period of time (yellow line on the above screenshot)
- Lowest Price Level (0%) - The minimum traded price of an instrument over a specific period of time (green line on the above screenshot)
