I don´t know what is happening but if for example I use a Proscreener like the one on this thread to filter out stocks that are below a certain volume (for example 100.000 daily stocks traded) and after getting the results I go to another webpage (like marketscreener) the volume in prorealtime does not coincide at all with the volume at marketscreener or any other financial website.

Even worst because if I run a proscreener to filter out stocks that are below a certain volume I still get stocks in the results that are below that limit and even with much lower volume than what I intented with the filter.  For example I set a proscreener to filter out those stocks in a market that are below 100.000 daily stocks and there are still like 20 stocks with volume as low as 5000 or 8000 stocks traded. Why does this happen?

I just want to filter out stocks that their average capital traded for the last 7-10 days is below a certain limit but I still get stocks that are way below this limit. So, how can we solve it? Or do the volume results in Prorealtime are very different from the real traded volume for any reason?

Thanks again!
