If you use market delta with Esignal you should be aware that the software produces erroneous results with Eurex data. The Footprint chart which is the cornerstone of the application will record totally incorrect information of quantities trading at the bid and the offer at seemingly random times. Given that this is the whole purpose of the software, and that the bulk of the educational material is about identifying opportunities from the footprint chart, it seems quite extraordinary that this should be the case. However anybody who watches the market during the day will be able to see these errors develop. If you refresh your data during the day with a download and the chart values on the footprint chart change, then clearly this error has occurred. Using this software trading Eurex and relying on the footprint chart would be very foolhardy indeed.
