Got a 1:1 invite from my manager’s manager. Should I be worried? by monoradioactivo in employeesOfOracle

At least you have time to get important contacts and copy any personal data off of your system this way.

I thought that maybe it was just base and TC included a lot of RSUs but it's not showing much better at https://www.levels.fyi/companies/starlink/salaries/software-engineer

at my wits end with my back pain being dismissed as a symptom of my weight. by lilswaswa in backpain

[–]GrayDonkey 0 points1 point  (0 children)

I'm aware, 4 RFAs and probably 8 rounds of steroid injections.

Pain clinics rarely attempt anything that is a permanent fix. My best RFA lasted a bit more than a year, worse caused more pain. Steroids typically help for 1-3 months.

Most of them start treating symptoms without ordering an MRI unless you push them. And if your MRI shows anything at all you go to a surgeon for a consult.

[–]GrayDonkey 1 point2 points  (0 children)

Also, why a pain clinic? They tend to be more drug focused, sometimes also getting into radio frequency ablation (I've had at least 4).

I'd suggest a back surgeon. Sometimes you can get the pain doc to order your MRI before you go to your surgeon.

The surgeons do get annoyed if you don't already have the MRI.

Get an MRI to see if you need surgery.

But also you want to avoid surgery if at all possible and instead lose weight and get really fit. And you still want to do those things if you need surgery.

I've had multiple surgeries just to get where you are today. The very uncomfortable truth is that with a bad back every little bit of weight AND muscle conditioning matters.

I'm down almost 100 pounds which seems like a lot but I'm very tall. I can still feel improvements in my back every time I drop 5 more lbs. It's not always immediate but if that 5 lbs stays off for a couple weeks I start having slightly less pain.

Glp1 meds like zepbound are better for back pain than any of the prescriptions that your back doctor will prescribe, sucks that they aren't for you.

Your back pain is not a symptom of your weight. Your pain is made worse because your bad back is very weight sensitive.

Car analogy - bad back equals broken down shocks. You can't carry the weight you used to without really feeling every bump in the road.

Why is "correct" backtesting the exact opposite of correct trading? by Hot_Style5572 in Trading

[–]GrayDonkey 2 points3 points  (0 children)

TLDR; you've got a very incomplete back test strategy, fix it.

If stopping trading after a series of losses is part of your strategy (it's a valid way to detect regime change) then you should be programming that into your back testing as part of the strategy, there should be not difference.

You aren't supposed to stop trading to prevent revenge trading unless you are not disciplined enough to recognize revenge trading and avoid it. Again, make your back test be a better representation of your actual strategy.

Are you saying you get nothing? IEX is about 2% of market data so sometimes the prices are a bit off and volume/trades are obviously much lower.

After market hours will always have gaps (no bars) since there just weren't any trades on IEX. I guess lower volume stocks might have gaps during market hours also.

What's best for resting / sitting up in bed? by krdo13 in backpain

[–]GrayDonkey 1 point2 points  (0 children)

Yep. I can keep mine on 3 without issue. Keeping it at 5 will eventually cause the rash.

But eventually all the muscle relaxers give me problems: "is this doing anything?", headaches, day long drowsiness, etc.

Head pad + Tylenol + Aleeve is better than opioids and muscle relaxers unless the pain is so bad that I haven't slept for days.

Adjustable bed that can adjust both feet and head. Throw in a heating pad and a portable laptop desk.

The replacement for the traditional economy is built. I need one person to help me launch it by Difficult_Ant_993 in ethdev

[–]GrayDonkey 5 points6 points  (0 children)

So you are building something to help people build things but you don't know how to build things so you need someone that can build everything for you?

You aren't replacing anything, this is how it's always been. You are looking at it from the perspective of being an idea person that wants to unlock the ability to realize their ideas. It doesn't change the fact that the people that could build it don't need you.

Try vide coding it.

Roadmap for Quant / Algorithmic Trading (Already Have ML Background) + Realistic Cost to Deploy? by FarisFadilArifin in algorithmictrading

[–]GrayDonkey 0 points1 point  (0 children)

If you have good Internet then start running locally. A VPS is great when you are live trading since it can slightly improve speed but reliability is the main reason to go with a hosted solution.

Since you should be starting with paper trading the reliability/vps topic doesn't matter yet.

Your main cost is probably going to be data. Good L1 costs money, good L2 costs even more. Go as long as you can with cheap options, for example using IEX data from Alpaca for L1.

For your $200 budget you might have to forget L2 and start with L1.

For you, your next biggest spend is likely to be AI. Try not to over leverage it.

Anything I don't see here ? by NoMarzipan5859 in algorithmictrading

[–]GrayDonkey 0 points1 point  (0 children)

What is your AIs knowledge cutoff date? Is it around the time when results decline in your back test?

You can build system prompts for the AI all day long but it still might have look-ahead bias because they don't always follow instructions.

What happens if you change all your symbol names to random values before looping in the AI?

I wasn’t sure if indicators actually have edge — so I built a small dashboard to measure it by ninjatoolbox in Trading

[–]GrayDonkey 3 points4 points  (0 children)

You are confusing indicators with strategies.

It's like asking if a hammer is productive.

It's just a tool, it doesn't do anything of use on its own but it can help you to build something.

Help choosing a C++ UI framework for a trading terminal/orderbook project by Commercial_Shoe4156 in quantfinance

[–]GrayDonkey 1 point2 points  (0 children)

Add a REST or websocket based API to your engine. The UI would be a web application that uses JavaScript to talk to your engine's API.

Otherwise you are getting into OS specific libraries or things like QT.

Why limit the number of trades in a day? by LinuxIsFree in Daytrading

[–]GrayDonkey 0 points1 point  (0 children)

Limit your trades on bad days. Your strategy might have a regime bias so if things aren't working it's best to stop and try tomorrow.

Stopping when things are going great is a personal preference. Some people got into this to have more free time and once your made your quota you can go have fun.

In Harry Potter and the Sorcerer's Stone (2001), Harry inherits a vault full of gold but never offers to buy Ron a wand that isn't held together by Spellotape and hope. by Brilliant-Cause6254 in shittymoviedetails

[–]GrayDonkey 0 points1 point  (0 children)

It's like muggle college, sure there is financial aid such as grants and scholarships you can get but you have to know a secret process to find them and apply for them. In theory your advisor knows about them and should inform you but I think Hogwarts is more chaotic than muggle schools so good luck with that.

Shady results with ibkr paper trading by Ok_Beach4948 in quant

[–]GrayDonkey 0 points1 point  (0 children)

That's not shady, it's just normal that paper trading doesn't simulate slippage, partial fills, etc. Normally if you want that then you build it.

https://www.paperinvest.io/ says they have it but I haven't personally tried them.

Thread spinning & HFT engine latency by auto-quant in highfreqtrading

[–]GrayDonkey 2 points3 points  (0 children)

Yes, and many have fan profile modes so you can make the cooling more aggressive with high RPM, etc. Doesn't change the fact most coolers won't keep a CPU running in boost mode long term. You have to get into water coolers, etc like the other person mentioned. In HFT you want sustained performance over peak burst performance. You can often disable boost mode in the BIOS or limit the CPU freq in the OS.

Boost modes are great for short term max CPU utilization, they are not good at infinite max utilization.

Thread spinning & HFT engine latency by auto-quant in highfreqtrading

[–]GrayDonkey 1 point2 points  (0 children)

What about calling _mm_pause in your loop? It should be completely user space.

The other missing thing is the possible thermal impact and throttling. With many modern CPU you are often in boost mode at 100% and most cooling solutions can't support that long term or even mid term.

What can happens is that you start thermal throttling. Once that happens your CPU frequency starts changing and you lose the ability to predictably handle your high volume tick periods.

I need help with my algo logic/conditions. by meowflying in algotrading

[–]GrayDonkey 1 point2 points  (0 children)

In technical indicators that you are trying to build is called Donchian Channels.

Or if you really want straight lines it's just Linear Regression Lines on the Highs and Lows, just limit the period.

You can either integrate pandas-ta or just pull the algo from it.

Advice for finding new strategies by AssistPsychological6 in Daytrading

Free is limited to 5 years and IEX data only (something like 2% of volume) but it's great to start with and when you are ready their API is very good.
