I did something like this on Hypixel for a month or two. Watched the prices for inputs to various crafting recipes as well as the craft recipes output prices themselves on a loop, and whenever it hit a certain profit level, play a chime and I would go run some crafts. Easy enough to pull the info off of https://wiki.hypixel.net , and https://wiki.hypixel.net/Travel_Scrolls were the ones that most often had good retur…

Arbitrage much more fun when r=0

Haha, in the heyday of Runescape it used to be possible to simply have buy and sell orders sitting in the GE for the same rare items simultaneously, and over time they’d both get filled for a profit. I guess you would call it “market making”.

This is indeed how market making works.

I made approx 1K GBP as a young teenager trading in RuneScape prior to the introduction of the GE. Haggle people down to say 6 mil for a party hat I'd sell for 6.5, repeat, when I quit the game I sold it all on eBay, my mum was rather surprised when the money came in. Hourly rate? Awful. I very much doubt that I'd be where I am today without that experience though.

What line of work are you in now?

This is actually kind of how the US market works with essentially 1 market maker who is by far the largest and who also happens to be the largest political donor (100 million a year to gop alone). Oh, and like Bernie Madoff, the owner of that market maker also owns a hedge fund (which like Bernie's makes completely impossible profits year after year). The hedge fund is of course a totally seperately run business from…

This is actually how markets are made - do you think a second hand book shop operates any differently?

Second hand book stores take people's money and then give them nothing in return? I'm referring to naked shorting and failing to deliver perpetually.

Sorry, I fail to see the analogy.

You appear to be referencing Jeff Yass and Susquehanna International Group. Why are you being cagey about saying so? Their hedge fund has had losing years, whereas, as far as I recall, Madoff never reported a loss. On what information are you basing your claims?

They're referring to Ken Griffin / Citadel (Securities). Not that it makes their claims any less silly in terms of fundamentally misunderstanding how markets work.

What claim about how the market works is silly exactly and why?

My claim was that 1 person owns the 1 major US market making business AND a hedge fund. Facts: they can control the price (naked shorting + strategic FTDs) and trade on it. Even if they can't/don't control the price, they can still front run the entire market. And even if they don't do that bEcaUsE iT's iLliGaL they legally (not ethically) do it through PFOF from Robin Hood among others.

They do all of that and way more. Just look up the continuous massive FINRA and SEC violations and the (tiny) fines they pay for it.

But I'm sure all is fine and dandy. I find it mind blowing why anybody would defend the biggest crook since Madoff.

You should be happy that market makers like Citadel Securities exist. Payment for order flow is why commission free trading can exist. Citadel Securities, Virtu, Hudson River Trading, Jump Trading etc compete in a negative sum game which reduces the bid ask spread on various assets (i.e. make them cheaper to trade for everyone).

Also lol that a hedge fund with about 1% of total hedge fund assets controls prices. What do you think the other hedge funds and trading firms are doing?

This reminds me of when World of Warcraft had a mobile app that allowed you to both browse the auction house and list or buy items. The API was pretty trivial to reverse engineer, making it easy to write an auction house bot. I never got as sophisticated as any ML algorithm, just snagged grossly mispriced items and bought/sold based on the last week's price range; it was mostly about volume. Made a tidy profit, bough…

WoW never cared about playing the market, it was probably taken down due to the way it was implemented. To be an external app, it probably had accounts idling and refreshing the AH and pushing that out to the app. I used the Auctioneer in game addon for a decade.

I used to wake up before school, dump my entire stack of gold on the GE for bones (just the regular ones) at a few gp below average price. By the end of the day the order would usually be fulfilled. Then I'd dump them back on the market at a few gp above average price and it would be fulfilled by the morning. Most days it would net me a small profit, ocasionally prices would fall slightly throughout the day and I'd l…

How could you lose money on a standing sell order for a higher price than what you bought it for?

If the market moves down after you bought, you are stuck holding the bag. You can either a) sell for a loss, or b) keep your item, and be unable to make further trades until the price (maybe?) recovers. Remember that OP put his entire stack into this, so he can't run the spread while his item isn't selling.

You can have unrealized losses since it's possible that the value of your items is less than the value of the goods you paid to receive them. To repeat this strategy the next day, you need to convert your items back into gold and realize the loss (or just introduce more gold via other means).

This is the bit that seems poorly substantiated and unlikely. Please elaborate. Anything evidence you can cite would be helpful.

Also, Citadel’s HF has definitely had down years.
