Hello, I’m using Thomson Reuters Eikon datastream first time, and have some question about deal the data. In terms of research, I need to find out realative financial variable (e.g assets, equity,EPS…) of multiple listed companies in ten years. I have found those companies , but I don’t know how to screen those data in according to my requirements, for example I want to exclude unlisted companies during this period,(some companies are not always at listing state during this period,at the beginning,they may didn’t list), or exclude some companies who have negative value of equity,or exclude those companies who has adopted IFRS accounting standard before 2005,what should I do to solve those problems? Hope everyone who knows can help me,thank you.@yishui2681
