Correct23, this is my first time ever seeing heat map charts. Those are interesting indeed.
Do you prefer using heat maps? Can you think of any pros or cons?
How did you decide to start using heat maps? Are they commonly used?
Heatmaps look confusing at first. How long did it take to get comfortable understanding what you are even looking at?
Do you use any special computer monitor for that?
Are you primarily trading medical company stocks? If so, why do you chose to focus on that subject?
What charting software are you using that supports heatmaps?
