35 ========== TODO ==========
36 16:36 <ceb> alpha,byrne,papaya,turtle,jorvik,luthien is my example
38 16:39 <ceb> Also, maybe colour to highlight the suggested trades?
40 16:40 <ceb> columns should be sortable with the small arrows as before
42 16:46 <ceb> Also trading plan not functional but I guess you know that :-)
44 use POST for update. Hrrm.
48 adjustable potential cost of losses (rather than fixed 1e-BIG per league)
52 16:38 <ceb> I don't know how hard this is, but can you show only the suggested
53 trades to start ith and have a button to show all?
