Options Heat Mapping

Through the settings, you can also highlight potential trading opportunities based on the relationship between your theoretical values and the market. You can highlight a Bid/Ask price when the theoretical value approaches the market by a number of ticks. You can also display prices in gradient yellow shades based on how far through the market your theortical values have crossed.

1. The theoretical value is highlighted white because the theoretical value is within a specified number of ticks of the market.
2. The lighter shade of yellow indicates the theoretical price slightly crossed the market, so indicates a small edge at that price level.
3. The darker shade of yellow indicates the theoretical price crossed the market by a greater amount, so indicates more edge at that price level.
