Do market makers trade in the same securities they "market make"?

<t>I have the book "All About High Frequency Trading" and within it it describes a HF set up. The imaginary firm provide quotes as a market maker, but the book also suggests the same firm also use proprietary algo trading. This seems a bit strange to me if they are trading on the same stocks they ar...

Markov chain vs Hidden Markov Model

<t>I just want to implement a simple "price predictor" algorithm (not for production purposes) and I have been looking at markov chains and hidden markov models. At first I started with HMM until I realised my observations (price increase, no increase) were the same as the "hidden" states I was look...

Basic Cash Equity/FX algorithms for High Freq?

<t>Hi,I am doing a project whereby I am simulating a high frequency platform receiving quotes from the market. However, I need some computationally-intensive algorithm, but preferably suited to cash equities or FX (because I am only sending very basic input information into the system- prices)?I don...

"q"-word is fancy, so they attach it to any job to attract people. you have to look at the employer and the group to figure out what it means case by caseThere must be some sort of general consensus what a quant developer does? Or at least...

Quant Developer- what do they actually do?

<t>Please note: "quant developer" != "quant analyst"I am doing a lot of things in VBA, mainly working with the Quant Team. Officially I am a quant developer but I dont ever get to touch any maths. Currently I am building spreadsheets to turn into models using the quant library. "Pricing" has been me...

Low Latency - C++ or Java - Current Trends

Well Java cannot be that bad because of the attention Disruptor received!http://martinfowler.com/articles/lmax.htmlAlthough, is it fair to say the Disruptor was more about throughput than latency?

FPGAs vs GPUs for high frequency?

<t>I am planning my dissertation which will be to showcase my skills for high frequency/low latency trading. I am planning to (attempt to) connect together two computers, one sends simulated data to the other and either:-hack out a lot of the linux kernel, re-write the network stack (write a new one...
