Hi, I am looking for a charting software which can easily show the previous chart. For example, I have a portfolio list, about 50 stocks. I want to check the chart on 2006-1-1, then pick my 5 long stock, then check chart on 2006-1-7. The key is I don't want to see the following days chart unless later I want to check the performance. Because that will impact on my discretion. Thank you.
