if by "all the coins you have" you mean your balance there all exchanges have some section called balance or wallet which you can see all the balances and their value in bitcoin and there is always a little text on top telling you your total equivalant balance in bitcoin.
try this link:
www.poloniex.com/balancesI think he just wants to see all the coins he currently owns/holds. try ticking "hide zero balances". if you tick that you'll only see coins have some balance, all the other coins will be hidden.
Yes, that was my intention and thank you, that showed me what I was looking for.
But still I feel they should include this as a separate option on their website where we can see our investments, show the price when we bought them and the current value of them etc.
That is what we all want to see I feel.
i am not so familiar with poloniex since i don't use it for trading but all the exchanges have a history which shows all the trades that you made with dates and times and prices.
you can export this history in .CSV format and it is a file that can be opened with Microsoft excel (or open office similar application) and you can do any kind of analysis you want on it. draw charts, get total profit, total loss, color the rows, columns.
using excel is pretty easy too, you can find many youtube videos if you got stuck.
