You don't need to peek the next tick, you can predict it (at least some of the time.)

What about thick stocks with 20k+ shares per side? There is a lot of midpoint volume in these stocks.

Two scenarios: 1) Cheap, thick stocks, and 2) Expensive socks When is it optimal to use the midpoint in #1, and when is it optimal to use the midpoint in #2? This is an open-ended question, just curious if anyone has a strong opinion on midpoints.

I fail to see how entertainment is some government provided right or why money should be taking from working people for entertainment they might not even want. If you argue it's tradition, then you might as well argue that looting from peasants and waging wars of conquest are tradition and just...

I don't believe wealthy people have a responsibility to me so I'd say whatever rate my rate is. On the flip side though, I feel like in Europe, the royal families should pay 95-99%. If they think they were divinely appointed to be kings and queens, then they have a divine right to take care...

Variance-bias trade-off, my good man. You decide how much trade-off you want to make, but just be aware of the consequences.

Simple question: Could a market-maker possibly make money over the long run in stocks related to the S&P 500 without looking at what's going on in the SPY or ES? Or is the correlation sufficiently high "most of the time" to essentially demand that market makers /always/ must look at event...

Bob111, I agree with you on this. However, those compulsive players, gamblers, and housewives would only contribute to broker internalized flow in today's markets, or the flow would get tied up in PFOF schemes. If you happen to be in a prop firm that has access to that internalized flow, it's...

Dark pools are cheaper if you can get the fill. Sometimes it helps to pick the meat from between the teeth of the alligators, if you're a bird (small guy.)

The idea that you can rise from humble beginnings is just something people like. Whether it's been socialism or communism or what have you, most people still end up (over time) in the position where upward mobility is difficult. The winners always essentially become the house in every system...

Maddox, is that you? http://thebestpageintheuniverse.net/c.cgi?u=irule2

The money and time involved aren't worth it for anyone in the US, unless they are in college and bored. We're better off just trading our own accounts with real money doing the exact same thing.

I used to end up faulting volatility as well, but I also happen to think volatility is an easy scapegoat in failed systems and try to avoid attributing my problems to it, ... as opposed to just identifying abnormalities as part of the system. Estimating volatility is somewhat error prone, and I...

My guess is that you don't truly understand the source of your edge (if there is one), so you aren't catching some variable that really dictates the performance. Please understand that I am not suggesting there's some flaw with you, I'm just saying there is a hidden variable you haven't isolated.

Some prop firms allow it if you specify it as part of your routing instructions.

Depends on what they charge me. Let's say TH offered commission-free trades to hit their venue, I would be hitting them all the time, even at a short-term disadvantage / inefficient price (conceding profit to their market making desk), particularly if my hold time was much longer. Or if TH let...

Bingo. I want the choice. Bring back TH with choice. It's not like you guys (IB) have that much to lose with offering us a TH route if it's by choice.

(Offtopic): Come on def, don't avoid the question. Can I trade directly with Timber Hill directly now if I want to, deliberately? Why did IB go all or nothing, why can't we have like a 'tmbr' route directly for us to probe before we go out and pay a fortune on some exchange?

I am using bayesian tools currently and am trying to expand my toolset, but having some trouble pushing my signal integrity past a certain point. The current trade is profitable but I'm not happy about the margins I am getting and want a smoother equity curve.

Oh, 100% agreed. I was thinking of using them in the context of validating rules and finding the right parameters around rules, as opposed to finding scenarios in the first place. I am not a believer in the finding-rules use for NNs. Like say I believe when X happens, Y happens. But what...
