Question on how the apps will work after the merger.
i know it's going off shore, and not everyones app will let them trade CSE. Mine can, so that's fine. My question is, after the merger happens, and my app no longer shows me holding CPH, but instead TRIP shares, what will it show as my average cost and the Loss, or (heaven forbid) Profit when the sp changes? Will it be a currency conversion of the total current value before the merger, or will it be set at zero, and we'll have to manually work it out ourselves?
