Hi, I am using the Swipe thing in Sterling (routing to ARCA/EDGX/BATS) to buy/sell at the best price. However, my entire order often doesn't get filled. I swipe to short 1000 shares and it sometimes fills only 0/250/600 shares. If you trade at a prop, your entire position will be closed once you break the stop-loss. How does that execution work? It always fills my entire position at the best prices. I wanna use that route to enter my order. Thanks.
