This feature does not work in Simulator. It does work in VV7, but there is no way to reasonably test hundreds of simulations using a step in approach in VV7. Using a $100,000 portfolio and a step of 2 stocks per day with a max of 10 stocks, the program buys 2 stocks with $50,000 each on the first day and no new trades are placed until one of them is closed, then it buys the rest (9 stocks) on the next day dividing up the available money.
