Yes, because the algos are being faked-out by the spoof. It's like being juked in basketball... if the algos were smart, they'd hit the spoof bid.

> if the algos were smart Algos aren't smart. Thy automate human reasoning to the extent logically possible. If as a human you don't know how to detect a spoofed bid, then how do you make algorithm "smarter" than yourself?

If the algos aren't smart, then you may wish to rethink trading real money with them.

The orderbook imbalance signal is a strong signal, but its not the only one...

(Full disclaimer: I worked as an algo quant at a large bank for 5 years. During which time I was constantly hounded by Compliance over supposed "spoofing", which we never did.)

No they would not do this. Why would they want to hit the spoof bid?

One should seek to determine the theoretical price (i.e. "true" price) of an asset. If the spoof bid is above the theoretical price, then you hit it. The spoof bid is noise... find the signal and make the spoofers pay dearly.

Ideally the less manipulation you have the better working market. So, it's good that spoofing is illegal. Their only purpose here was to: "Through these spoof orders, the traders intentionally sent false signals of supply or demand designed to deceive market participants into executing against other orders they wanted filled. " That being said, algos could have hit the large spoof bid, but imagine if it was legitimat…

> That being said, algos could have hit the large spoof bid I would guess that they sent a bunch of orders and them immediately cancelled them. If that's what they did, then by the time other market participants see those orders (remember network latency), the orders will already have been cancelled, in which case it would be literally impossible to trade against those orders after having seen them in the market data…

If this is the case, the real culprit is the exchange. Rather than offering premium "flash" facilitating services like colocation for HFT traders, the exchange could do something like 20-second auctions during which time orders can't be cancelled until the next auction interval.

What's the difference between a spoof and bluff in poker?

The spoof can be pulled after a few seconds, once it's done its job.

Exchange should make a minimum order validity interval during which time you can't cancel, e.g. 15 seconds. Problem solved.

Oh sure yeah but it's unlikely spoof bid would be above theo.. too risky on the part of the spoofer

Legitimate liquidity would disappear, market makers can't manage risk

Why would I look at just their trading revenue? The fine was levied against the entire company, not just their trading subsidiary. >settling charges against JPMorgan Chase & Company (JPMC & Co.) and its subsidiaries, JPMorgan Chase Bank, N.A., and J.P. Morgan Securities LLC (JPMS) (collectively, JPM)

> Why would I look at just their trading revenue? Why should you? Suppose you did a bad. Let's it was a side hustle where you took refurbished ipads and resold them as brand-new ipads. Over the past year you made $2000 in profit from doing so. The cops caught you doing it and fined you $10k. That sounds like a pretty serious penalty. However, you're also a bay area software engineer making $400k total comp, so $10k i…

> Should they fine you $200k instead

Yes, the fines should be punitive, not proportional to the damage.

Instead of worrying about the banks he should have been worried about the moral fabric of the country. At least since the bailouts 2008 there is a (mostly justified) perception that the system is rigged in favor of the wealthy. This has made a lot of people very cynical and has allowed a ton of conspiracy theories to rise. If this trend continues there will be a point when people will vote in a dictator. It’s already…
