I work with CMC, and it is not possible to connect to Prorealtime. My sp500 point is worth $ 50, the issue is that unless you can change this by formula I can not change this.
Finally I have increased the portfolio to 5,000,000 and the percentages give me correct. Anyway I am very grateful for the interest shown, you can not imagine how much I have learned when reading the questions raised in this forum.
Thanks again.
