The data quality and management is low
The data quality seems low sometimes, especially in the high tact price data, for example 1 min tact.
This is highly unprofessional, I had to filter the errors out myself, which took me like a week to code. How does it come that a company which is trying to do this professionally, doesn't have a basic filter for the data it's providing?
But there is more, which is actually a bigger issue. They don't provide any fundamental data on delistet companies... The main reason why people are requesting historic data, is to run simulations with it. If you don't provide the data on delistet companies and actually proceed to delete it, there is no possible way to run non bias simulations. This is a very questionable data management and in my opinion highly unprofessional.
