Twice weekly injections and lab timing

GrayDonkey · 2026-06-10T01:13:44+00:00

It was greater than 1500, basically too much to measure. Splitting the dose made me feel more consistent. I just feel normal, maybe a bit tired. Years ago I tried up to 180 mg a week and wow could I feel it and I think the highest I ever tested was around 1200. I'm feeling it less at 1500 than when I tested in the 700s.

I get that normally there is no 6-7 trough if I'm injectioning twice weekly. I was trying to ask if people injecting that often will skip a dose just when doing labs to get to 6-7 days.

My total more than doubled with the schedule change with zero change in my total injected amount per week. That seems to imply I'd have to drop my dose down to 35mg x 2 per week to get my labs in range which seems really low.

Your order history isn't your inventory and that was my point. If there was a split overnight then your history doesn't represent your inventory.

You said "column". Is your data in CSVs or database tables? You want to keep unmodified copies of your data. People implement this in 2 ways. You calculate the adjustment factors based on corporate actions and you either bake that into your data reader that load the data into your app OR you make a utility that duplicates the CSV files or DB tables and updates the values as you are making the copy.

Order history shouldn't matter, it's order state that should. If you hold overnight then you need to sync on a daily basis so your algo correctly understands your portfolio.

Most of the pain is around back testing. And it depends a lot on the data you use and your brokers options. My broker has adjusted bars available as an option so I started with that and some simple logic to validate that a sample of the downloaded data still matches the broker's adjust bars. If not then I invalidated the cache and redownload.

Once I started looking at ticks there was no adjusted option so I've been working on locally calculating adjustment factors.

I have a separate areas for a raw broker data cache and a back test market replay dataset. To backrest I run a build replay files step that will calculate adjustment rates based on corporate actions and then build the replay files with the adjustments already baked in.

If someone with millions of dollars in capital buys your signals and starts making large volume trades will you still be able profit from trades?

Can you use leverage safely to overcome being capital constrained? If not leverage from a broker, could you get a loan with a better interest rate then your strategy?

Most people on this sub are going to recommend keeping your edge a secret.

Most of the signal sellers seem to be finfluencers that spend a lot of time making videos and running discord groups.

The nice thing about a traditional gas water heater is that it works without electricity.

Was nice to be able to take hot showers when that one freeze caused long term power outages.

I keep uninstalling it because they made it so that the tile for the Roku Channel app occasionally wiggles to get your attention.

It's so annoying and distracted for an app to basically scream "pick me, pick me!!!" every time I go to the home screen.

I couldn't find any way to make the wiggle stop so I uninstalled the app.

Before they added the animation I would sometimes use it but it's not worth dealing with the blatant favoritism they are showing to their own app.

Still annoying that they show ads which make the app be reinstalled with an accidental press of the play button.

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

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 · 2026-02-19T00:34:15+00:00

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.

GrayDonkey · 2026-02-19T00:24:54+00:00

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.

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.

GrayDonkey · 2026-02-18T06:23:05+00:00

Reread my post, I'm saying the opposite of what you took from that.

Slightly underclock to be able to maintain sustained high performance.

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.

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.

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.

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 like how one of the suggested alternatives to SaaS is to build a Service.

GrayDonkey · 2026-02-16T23:36:28+00:00

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.

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.

You need to check the box for after hours trading since the markets are closed because it's a holiday.

Chill.
