a chart with more than 16 tickers does not look correct

Look at pic below of a chart with more than 16 tickers (total of 30 tickers on a 10 min bar chart):

First, the UI doesn't do justice to the remaining of the tickers (beyond 16).
Second, it is quite slow, and a playback takes 5-10 minutes to actually load to the playback stage. (It is fairly unusable, for most users).
