hi
regarding vantagepoint, i bought the 3 market module from tradertech around the end of 2005, the 3 market modules were Dow jones index, the S&P500 index, and EURO/USD.
basically, you have to subscribe to an end of day data provider, recommended by tradertech, which costs around $30 U.S.D per month.
you download the data at the end of each trading day, or early the following morning and the vantagepoint software provides you with predicted highs and lows for each of your modules for the next day's trading session, plus tells you whether they consider the short term and intermediate trends to be up, or down.
the idea is that, say the software considers the short term trend for the Dow to be up,they suggest you wait for the Dow index to drop down to the predicted low for that particular day, then buy at or near their predicted low, and hopefully selling at a higher price either intraday, or after the index has risen strongly for a few days.
in my opinion the software is too expensive, plus you have to pay out each month for the data feed.
if you need any more information you are welcome to send me a message.
best regards and good luck with your trading.
