It is possible with event driven software to fail where a polling model would work more accurately. If each order was scanned and compared to the current price, the stops would execute. If the software waits for the price to be equal to the stop price to trigger an event, that event may never happen because it is possible for the price of the stock to jump by more than a penny and skip over the stop price. Stocks that trade at low volumes often have a wider spread between the bid and ask prices. Prices can change by a nickel or dime at a time. It may be logic that expects two lines to intersect that never do. Or the intersection between two circles that do not touch. Try this: buy a stock that is falling in price. Place a sell stop order at 2 cents above the current price. Does it execute or remain open as the price falls below the stop and never crosses it? I won't be satisfied until this is solved!

How can you NOT explain this? September 30, 2008 10:29 AM Market Short 2700 TBSI @ $12.95 Order#529F08 Order qty reduced to 1600 (Significantly different from my valid order) 10:45 AM The current price of TBSI is $13.23 10:45 AM STOP COVER GTC 2628 TBSI @ $13.21 Order#E04D97 (note difference in qty does not coincide with above qty) THIS ORDER SHOULD HAVE EXECUTED IMMEDIATELY AS A MARKET COVER BUT FAILED TO DO SO. 11:00 AM Current price of TBSI is $12.9611:15 AM Current price of TBSI is $13.35 2nd chance to execute stop cover failed again!11:30 AM Current price of TBSI is $13.70 Stop cover order fails to execute - it has plenty of time and difference in price. 11:41 AM I noticed the price of TBSI was well above my STOP COVER order price so I cancelled the STOP COVER ORDER THAT FAILED TO EXECUTE!!! 11:41 AM Market Cover 2628 TBSI @ $13.76 Order#213094 6.25% LOSS - My stop loss order was for 2%. This is clearly a bug and I don't know how the technical staff can deny these facts! When the price rises above the stop cover price - a market order should have triggered. It remained as an OPEN STOP COVER ORDER for about 1 hour before I noticed my losses exceeded my stop loss order percentage by more than 3 to 1. This is clearly a BUG! And it should be investigated more thoroughly before you deny it again. The facts do not lie. It is quite obvious that something is wrong here. I did not claim that ALL stop orders do not work. My claim is that under certain conditions SOME stop orders do NOT work.

Is Canada cleaner than the U.S.? Did those trees grow back that were killed by the Ohio power plants pollution from acid rain? Would like to move to B.C.

Thanks for being my buddy & happy trading!
Richo8221 I do not use STOP orders, I sell my stocks at what I perceive to be their HIGH, although when I do sell at a profit (shown on my dashboard) the WSS changes my sell price because I cannot afford ( am disabled on limited income) that Real time, so when I sell it at let's say $3.00 it does not stay that way in my "Order History" because I can't buy the Real Time thing at $10.00 a month. So they (WSS) can make your sell price anything they want... How can the average player even think of having any chance AT ALL??? delete 10/6/2008 3:56:45 PM
