This thread has been hijacked by HFT interests.
Cancelling orders doesn't imply that the orders were initially places without the intention of them being executed.
HFTs are trying to make markets. To make money as a market maker, you need to be able to cross the spread before the market moves against you. They need good queue position in order to do this, so they send orders tactically at several levels on either side to maintain good queue position before the market actually reaches them. If price reaches that level but it's no longer a trade that the market maker wants to take, they cancel the order. They fully intend to execute the order when they place it, but something along the way convinces them that they're unlikely to capture the spread or that they have too much inventory representing a similar directional bet on a given security, so they simply cancel. There is no attempt to mislead other participants here and nothing manipulative about this activity, unlike spoofing.
Exchanges like CME provide mass quoting in their protocols to facilitate market makers doing exactly this without it counting against them in the Efficient Messaging Ratio calculation--one of the rules put in place to discourage manipulative practices like layering--a form of spoofing that people who know what they're doing prefer to spoofing because it's more deceptive and easier to defend as a legitimate market making tactic. There are a myriad of other accommodations made by exchanges to encourage market makers and make sure they provide continuous liquidity because it leads to more fair markets.
Nobody at Jump will ever face a serious punitive action
I don't know what you consider serious punitive action. But a trader at Jump actually did get hit a year or so ago with a spoofing charge. James Chiu
And here is another problem. There is no clear cut definition of HFT. You are saying it means writing direct to an exchange. Someone else says a high cancel rate, someone else says a lot of orders. When it is this wishy-washy, people can bend it the way that fits their needs. I think we just need to get off this whole HFT business. And just go after people spoofing. HFT or not.
SPOOFING Doesn't WORK either. so he got fined for spoofing even though it has no effect on the market.
This true to a degree, not all HFTs are market makers, but many HFT companies' bread and butter is market making. You don't need to be a DMM to make a market. Anyone who uses a limit order is adding liquidity, anyone who quotes both sides has made a market.HFT are NOT market makers. and don't have the advantage of a 'designated market maker'
HFT are just professional traders/investors in the exchange.
Shenanigans. Shenanigans goddamnit!

See what I did there? My paragraph is just as valid as yours.
