from the glossary at the bottom of each page:
I placed a trade and the price I bought it for was different from the one on the confirmation screen. What gives?
Ā
The Exchange is in constant motion, and sometimes prices move up or down in the time between the submitted trade and the point it is executed. Sometimes this it to your benefit, other times, not - but it is usually only a few cents in any case. Veteran traders often refer to this as "slippage" or "chuckage."
Commission
There is no such thing as a free lunch in Hollywood and the same goes for the Hollywood Stock Exchange. Commission is the amount charged to execute a trade. All trades made on the Movie Market are subject to a one-percent commission, with a minimum of 2 cents per share, automatically deducted from your portfolio.
