There are a number of order types that are not generally available to non-Professional traders.  Some of these orders that Bright traders use are:

Opening Only

• These are limit orders that are entered before the opening.  They are executed only if the opening price is the same as or better than the limit price. If they aren't, the orders are immediately canceled so you don't need to worry about them executing later.

Market On Close(MOC)

• These are market orders that guarantee execution at the closing price.

Multiple Buy/Sell orders

• Multiple orders can be entered for the same or both sides of a stock without concern for capital issues.
