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.
I don't understand SWIPE but do understand Sterling. Are you trading for rebates? Why not send your order to where the liquidity is? Are you saying that there was liquidity there but you didn't get a fill? What type of order are you sending? Can you pay through to ensure a fill?
