Ok, I have two reasons I can give you.
For one thing, there actually was a problem with orders via market makers today. Etrade was having problems with all day where orders were sitting and they weren't getting execution confirmations. I spoke to them about it and they said it was a gliche that was not on their end. Now, I had no problem getting orders filled with choicetrade today.
The second reason I will offer is that you are using GTC. I have no idea how valid this is, but a good friend of mine who was a broker once told me to always use a day order over a GTC - that they fill faster. I remember him telling me "if you have to put the order in everyday, then do it over using a GTC" - I have never heard of anyone else offering this theory so take it for what it is worth.
