eyx··on Ask HN: Freelance developers, how much control do you have over your schedule?
In my case I have to be available for an 8-5 work day like a FTE.
eyx··on What Is a Gamma Squeeze in the Context of Stock Trading?
That's the theory, it's not my point.

My point is that a market maker will not carry an option position that is impossible to hedge due to the underlying liquidity. In other words, he will not carry a gamma position that is not "in line" with the liquidity of the underlying.

I may be wrong, but the article is about buying a lot of short dated (high gamma) call options from a market maker and hoping that he will drive the market up while hedging his position.

eyx··on What Is a Gamma Squeeze in the Context of Stock Trading?
Market makers are not only motivated by commissions.

Before making a price they will consider multiple factors, liquidity (of the underlying and the derivative) is an extremely important one. They likely will not carry a trade that is impossible to hedge (because the underlying is not liquid enough).

eyx··on Ask HN: Consultants/Contractors, how do you incorporate paid sick leave?
It would be a clause on a contract to be paid a given amount when sick (and thus not working) ?

I'm rewriting it because it seems so uncommon that it may be that I didn't understood your question.

eyx··on Writing my first Gameboy Emulator
Really interesting.

How long did it take to have a working emulator ?

eyx··on Ask HN: What’s it like being a Quant or Quantitative Programmer
I will reply for the quantitative developer role, given your description I suppose that it's what you are looking for.

Succinctly, I would say that it's a strong computer scientist/developer highly interested in finance to be able to understand/discuss/implement business requests.

It's important to be able to work under pressure (when there is a problem on an automaton for instance, etc.). It's also important to be able to frequently switch between tasks.

I would not say that you have to be extra smart.

I started as a computer scientist in a bank, turned quantitative developer and then trader a couple of years later.

eyx··on Ask HN: Why aren't you switching jobs?
I did not have to, I had the chance to be the "natural choice" when a trader left the desk.

I joined the desk as a computer scientist. They quickly gave me the opportunity to develop the strategies with them and thus to understand/know the business.

At the bank for which I was working, this kind of move is not uncommon.

eyx··on Ask HN: Why aren't you switching jobs?
Because it's not only a matter of salary, you have to put "all in the balance" when considering a potential move. Personally, I was giving a lot of value to the mobility within the company.

I started as a computer scientist in a bank and became a trader a couple of years later.

Outside of my company, it would not have been possible because I didn't study finance.

eyx··on Show HN: Robinhood users vs. the S&P 500
It would be interesting to be able to see the historical weight for each sector.
eyx··on Mutant garden (cartesian genetic programming)
Thank you for this clear explanation
eyx··on Mutant garden (cartesian genetic programming)
I'm sorry if it's obvious, can someone explain what it's meant to please ?

On my case (Android and firefox) it's fast and seems to work well.

eyx··on Show HN: Is this headline fake or not?
It took me a while to figure out that I should drag the headline left or right. I first tried to click the red "fake" and green "not", I tried to click on the headline, etc. I then realized that it was written in the light grey message to which I was not paying attention.

It may be my fault, just giving the feedback in case it can help to improve the UX.
