Hi again, I want to clarify how this calculator could be used by many traders.
All stock trading systems regardless what they are produce a buy and sell dates. My system tacks QQQQ Nasdaq 100 and it produces about 20 to 30 buy or sell signals a year. It is easy for me to keep track what my profit or loss is for QQQQ (one stock), but if I want to see what my profit would be had I traded for example Nokia, IBM, Dell or any other stock according my signal dates it gets very time consuming to do. I have to look up the open prices and manually calculate the profit or loss for that particular stock on 20 to 30 trades.
If we had a atutomatic stock calulator that I am looking for, All the different stock systems out there could easily see how their trade signals would have worked with other stock that they are not actively following. And I think that could be very useful for many people.
I went throug many sites and cannot find the one I want, this site being one:
