This panel shows you how fast the markets move by displaying the last Bid and Ask ticks.
Using the spread, you can see if it is time to earn money... for you or the broker.
This indicator returns nothing but the panel. So it is not useful for Expert Advisors. However, it is a great tool for manual trading or developing trading strategies.
You can adjust how many ticks you want to see. The panel suits up accordingly.
For incoming ticks the background is white and gets darker with time. After 30 sec, the background is black.
