Hello Edu,
that is quite interesting! Have you tried uploading different data into EA Studio, with a different broker?
At first glance, I do not see anything else but the spread (which you said you have tested with variable values)
Tomorrow morning when my head is fresh I will have a look at the pictures again, but give it a try with other broker’s data. Just to see if the problem is with the data that you export from the broker or is it something on the settings in EA Studio.
