When day trading or swing trading mega cap stocks such as Microsoft, Facebook, Amazon, and Apple, how big does the order have to be to really hit noticeable slippage? I found a rule of thumb that says if your order is under 2.5% of the average dollar volume, you should be safe.
Would the slippage with a $5,000 order compared to a $500,000 order be substantial or is $500,000 for an order normal? Is $100k an eye catching order size?
This is in the context of market orders.
