A couple of suggestions/requests:
1. See all shares/offers on 1 page (preferably without needing to scroll or zoom out) instead of having to click yes, no, or offers.
2. Show profit/loss on trades executed at current bid/ask instead of cents up or down from initial buy-in price.
3. Option to liquidate some or all assets (simultaneously).
4. Sortable/customizable order of assets (sort by expiry, P/L, popularity, volume, ...).
5. 1-day charts! (Not just 7,30,90 day views.)
6. Comment markers (show on 1,7,30,90 day charts when comments were made or when major news breaks...)
