      Yes, finance people are just mostly stupid. Most of the work is done by people of other fields and are just hired by them. Smart people will not want to make money when they are 12 tears old. Most of them want to make usefull products like video games or other stuff. Finance is something you do because your forced by your family. Or because you have no idea what to do with live and then selects a easy education wich gets to mutch repect.

    Once I cheeses some API by crafting my entire request in a single packet while other applications where sending 2 or 3 packets.
    But this is on another level, I did that to save resources in a GPRS network and get priority over the other credit card transactions of the other customers, thus my system would complete transactions faster and give a better sensation for the end user when the CC network was congested.

    Cheese strategy = a strategy which focuses on the holes in the system (the cheese)
    Eg if a broker has a glitch you exploit that glitch for a winning strategy
    This cheese strategy for trading is based on exploiting TCP in the technical stack (OSi model)

    It's kind of funny how they are literally exploiting every single layer of the communication stack. Since they have gotten their fiber link and reduced their latency now they have to cheese the communication stack and possibly any other layer of the communication layer to maximize their execution. It's actually quite interesting.

    I think perhaps its not the TCP "messages" that are incomplete, since it is just a packet stream and knows nothing about the contents. Its the FIX messages that are being split over multiple TCP packets, such that any given FIX Buy/Sell message is incomplete. So not the transport layer, but the session layer that is being held up on incomplete messages?

    • @rupertsmith6097
      @rupertsmith6097 4 месяца назад

      Also seems like little advatnage to be had here. A FIX Buy/Sell message could be only a few hundred bytes and fit into a single TCP packet. The last byte will also take a single TCP packet. Unless these Buy/Sell messages are unusually large for some reason (like trading more complex instruments that need many more parameters or something)?

If you're getting info from other location, you transfer it via microwave instead of cable (which 1.5 faster because of cable refraction index) 3. You run your strategy on ASIC, regular computer or even FPGA won't be fast enough. After all of that you may gain maybe extra 100 nanoseconds. It might seem insignificant but if there's someone else who've done 1,2 and 3, but not your trick, then you're going to be faster and you will consume all this HF alpha.

    @petedoe6872 4 месяца назад

    In your analogy, you still mention that the last (non-corrupt) byte gets sent to the corresponding trade order (for instance, to a "bullish trade" for good news). Does that not mean that they would have to wait for the news to decide which trade should go through? So the order would be: wait for news - interpret as bullish or bearish - send last byte to corresponding trade. How would that be faster than *not* having your trade already 99% of the way to the exchange, since you still have to wait for the news? Surely it can't be due to the time difference that it takes to send the prior 9 bytes of info (in your example)? Is that all the edge they need?

      Depends on implementation. It's basicly a slow lorris attack on a exchange that apperently did not have a computernerd working for them. It's older then a VIC20 this technique. Also using TCP for exchange is a bit overkill. Just look at the different order types there are and how big a order is in information terms. Think you can fit a order inside just a couple of bytes. I see it more as s business men crying like a baby when they meet a computer nerd. Computer nerds go to jail when they cancel a order, business men do not. And autistic people go to jail for growing there account to astronomic sizes and not taking actual profits.
