What does the recalculate button do?
On the “make a trade” page, the recalculate button calculates how many shares of the stock you could purchase, given the amount of cash you own. On the “buy/sell wizard” page, given the number of shares, percentage, or dollar amount, the recalculate button will derive the other values, as well as give you the current price, share count, percentage (of the fund) and current dollar value of your position in the stock.
