Open/close positions from chart
Dividend automatic reinvestment
Transparency on FX cost when dealing in other currencies in the "History" tab - my account is in £ and when I buy shares in $ I don't see any commission, but I end up paying a variable FX cost. That should be clearly visible, not incorporated in the total transaction amount.
Trailing stop loss
Ability to reorder watch lists on the left menu
Show stop/limit orders on chart
Ability to remove sections in the left menu (i.e. not interested in cryptocurrencies)
In the "history" section I see value always negative even when I'm selling (which should money in, not out). I guess this is a bug.
Adding funds and more stock markets (i.e. Italy missing)
Most of those points would be solved giving access to share dealing to PRT.
I think you have done a great job, needs just some fine tuning.
