I think a good idea would be for stocks to show their net balance on their instrument History. A lot of traders buy and sell on swings and this would be a great way of identifying how much you’ve made from a specific stock or probably in my case lost lol.
You do it for the overall account so don’t see why you can’t do it on an individual basis. Just need to work out sales Profit-Loss.
Don’t know if any of you guys have put this forward.
