Here is the appropriate help section from the live 
screen:

What is a stop or a 
stop-limit?
 Stop 
Order is a buy or sell order which automatically converts to a market order 
and will buy and sell securities at the current MARKET price once the order is 
triggered by the stop price.  For OTC orders, a stop order becomes a market 
order if either scenario takes place.  The stock is quoted (bid for sell 
stops and ask for buy stops) at your stop price or actually trades at or through 
the stop price.  For listed stocks a customer is entitled to the next sale 
on the primary market when the price trades at the stop price, providing there 
are enough shares available at that price. 
A stop order may be a day order or a good til 
cancel order.  A limit order is not the same type of order as a stop 
order.  Buy stop orders are placed above the current offering price and 
sell stop orders are placed below the current bid price.  A stop order 
gives you the opportunity to protect a profit or limit a loss on a security 
already purchased.  Be aware that significant, short term market movements 
may trigger your stop order, creating an undesired/unwanted buy or sell.  
Also, depending on market conditions and the fact that your order is a market 
order, once triggered, there is no guarantee of what price it will be executed 
at and can be several points away from the stop price. 
Stop Limit Order is an order to buy or sell 
a security at a specified price or better (stop limit price), but only after a 
given stop price has been reached or passed.  It is a combination of a stop 
order and a limit order.  A stop limit order may be a day order or a good 
til cancel order.  Unlike a stop order which converts to a market order 
once order is triggered by the stop price, a stop limit order would only be 
executed at the limit price or better.  As with any order limited by price, 
the risk is that you have the opportunity that your order would not be executed 
if the market price does not reach the limit. 
Stop Orders and Stop Limit Orders are handled 
differently by the exchanges and are considered “not held” orders.  No 
priority is given to these orders and you may not be executed, even if the stock 
is trading at your price. 
***NOTE:  
Stop orders must be placed at least .25 of a point below the current bid or 
above the current ask.  We have established this guideline due to the 
possibility of the order being invalid if the market price moves below the 
designated sell stop price or above the buy stop price.

  <<Scottrade supports all but Mkt on Close, End of 
  Week, End of Month.Nor trailing stops, the thing I'd like to see added 
  next.  The othersare supported.>>I looked at the demo 
  Scottrade online trade entry screen. It allowsyou to enter a Sell... 
  Stop... GTC... order on an existing Longposition, or a Buy to Cover... 
  Stop... GTC order on an existing Shortposition. What the demo trade entry 
  screen did not show was how tospecify a Stop Price at which to execute the 
  order.If a price specifier is available under the live trading system, 
  thenthat is all you would need to implement Stop Loss orders, and 
  thenmake them trailing by manually adjusting the Stop Price nightly 
  orperiodically.Hard to believe that Scottrade does not allow you 
  to specify a StopPrice in the order entry screen.Phsst---
