Geez that doesn't make sense I'm in Canada and can flip as many times as I want. But we do have higher fees they used to be $29 to buy then to sell $29 plus a %....sometimes to sell $7k of a stock would cost $180.
Now we finally have the $9.99 or $14.99 flat fees and with some we can do multiple buys and sells for the one flat fee in one day.
