All day long, multiple times a day, bringing the price of stocks to the Maximum Pain point every day. How could anyone think the market is not rigged? Yes I understand that with the limited info lvl 2 provides, 10000 shares could wipe out what you see on the order book on one side. All this means is that LVL 2 is rigged to prevent us to have a clear picture of what is going on. A good understanding of Statistics and Probability theory is all you need to watch this market activity and know that what was happening was price fixing.
Bullshit HFT algos are designed to manipulate and cause maximum pain/run stops. That is a fact. That is why you can NEVER remove liquidity with any size without the stock/ETF immediately flashing the opposite way of your entry. And the only way to get filled adding liquidity with size is if the stock is going to rip through your entry point.
