Hello, I scalp U.S. stocks that have an average daily volume of 7+ million shares. My average (limit) order size is about 2000 shares and the order gets filled easily when it becomes marketable. If there are any profitable stock scalpers here, what do you assume the size limit to be in $ for efficient (<1 second) executions on those liquid stocks? Thank you.
Ce fut un plaisir xD Seriously ... Liquidity depends on multiple factors. Today’s potential might not be tomorrow’s potential. If you really want to know then look at the time and sales and / or level 2 (Depth of Market). It will give you an idea of what size trade at each price. Usually the open and the close is more liquid. As I said ... Liquidity depends on many factors. But don’t bother with scaling constraints until you face the problems. I believe you have already enough challenges.
Here, for exemple, you can see the last 5 prints on AAPL. I see at (more or less) 361$ 100 contracts = 36,100$ 100 contracts = 36,100$ 608 contracts = 219,488$ 200 contracts = 72,200$ 260 contracts = 93,860$ These were filled within 3 seconds. It’s about $152k per second or 422 contracts These could be yours.
