i have trade for 20 years off and on from day trading to swing to investing and the one order that I nver really paid much attention to was the cancel. I never even looked at it as an ordr typer or that it had POWER to move the market. However, spoofing has shown that cancelling has a lot of power and that AGGRESSIVE cancels by an HFT or ALGO can actually force Aggressive orders by retail to get filled.
The cancel is free. there is no TRANSACTION COST OR RISK to use a cancel of an order. This cancel has no commission and not fee. Yet the if you place a 300 lot buy limit on the order book at the cme.. you can cancel 299 of them and your 1 lot now keeps it's priotity in the book... so if the 1 lot gets filled and no other orders come in within that microsecond then the next trade would be lower as now that the 1 lot level at price was matched..the spread will move.. lower by that tick.
