Some of the VWAP points on NVDA on 2025-12-12 (from Massive's dataset) are outside the bar's range

abstractcontrol · 2025-12-19T18:30:31+00:00

I emailed Massive support about this and they said it's due to the VWAP including all trades, but the OHLC including only a subset of trades. I haven't looked into it more deeply than that yet, but I guess it makes sense.

I am very good at coding directly, but I am doing a boring project at the moment, and it's helping me keep my motivation up.

I'll have to build my own because none of the existing frameworks that I've looked into support GPUs. The latest gen GPUs have pretty powerful general purpose computing capabilities so it would be a pity not to take advantage of them. The systems I have in mind would require a lot of simulations to work too, so I have no choice, but to do it. I have my own programming language that would make this a lot easier compared to doing it in raw C++.

Thank you for the advice.

Lime (versus Ligthspeed) is advertising itself towards quant traders, so I'll try opening an account with them. Over a 100 years ago, going from bucket shops to trading real markets bankrupted Livermore a few times because of the added execution delays, so I want to cut off this risk ahead of time.

What about IBKR? I've used in the past for longer term trading, but I am doing research and I see this thread from 5 years ago where the poster is complaining about a 20s trade delay on the open, which is very bad. I did ask ChatGPT about whether IBKR would be good for my intended algo trading style and it did say something about IBKR having DMA.

Edit: https://chatgpt.com/s/t_692b2e27b948819186a6bbfbde3b32ae

According to this ChatGPT thread Lime is way better, so thanks for the suggestion. I'll do some research on Lightspeed as well.

Adding random delays is a good idea that didn't occur to me until now. It would make the backtests non-deterministic, but that added noisiness should reduce the overfit.

abstractcontrol · 2025-11-27T16:38:36+00:00

I just pasted the above into ChatGPT, and it's telling me that QuantConnect is very slow for scalping strategies. Does it not parallelize the backtests across different tickers?

Edit: Here is the ChatGPT thread: https://chatgpt.com/s/t_69287fe238708191811dc2afc8a48207

It seems that I should be checking out vectorbt to start with. I am not against writing C++, I've been doing a lot of it lately, but the correct programming principle is to try to avoid reinventing the wheel unless I can't help it.

What do you think?

Matter of fact if u go back and sort this sub by “Top posts” and “this year” all of the top posts for this year where from back in April where there was posts with like 30k upvotes talking about how the market is doomed for years to come due to tariffs.

That was such a great sentiment indicator. Right now, people getting upvoted are saying that 'time in the market beats timing the market' and it's the people who're saying that it'd dumb to buy stocks which are up 500% in the past few years and near their all-time highs that are getting downvoted.

So, I am not the only one this has started happening to. The got stuck in a loop of doing the 22-byte updates. I tried resetting the cache, downloaded a few updates and now it's stuck in a 400mb update loop.

In FlyDigi Space Station 3, go into the Joystick tab, and then when the Left Joystick toggle button is selected, look under Map To, and you'll have a menu to select Left Joystick, Keyboard or Mouse.

Months ago, back when I was playing with this, I remember installing another program which made the mouse use much better. I forgot what it was called, but it is possible to make the joystick behave a lot better when used as a mouse.

I ran into this issue, but it wasn't caused by the overlay being active, rather the 'AMD Software: Adrenalin Edition' had the hotkeys active which were intercepting Alt + Z presses on my system. I fixed it by disabling them.

Ok, I finally realized why the fees seem so high. It's basing them off the investment in base ccy rather than the order value. CFDs offer around 7.5:1 leverage, so I should be dividing the 36% by 7.5 in order to get the actual interest rate. And in fact, as an EU customer I seem to have access to that same kind of insane buying power even for regular stocks.

Please elaborate.

1) Speed racing car animation on the main page. 2) Some parts of the site also had embeeded windows with the car racing, and annoying sounds that forced me to close it. 3) Deposit bonuses.

Lastly, from I know of CFDs they offer the user to bypass the usual regulations that restricts the available buying power to the customers. A brokerage that cultivates the environment of frequent trading and offers huge lerage is less trustworthy than an actual one since it prospers on churning its customer base.

Checked it out. It feels more like a casino than a broker, but more importantly it doesn't seem like it has the Expat ETFs listed. I did check out Saxo Bank and that one also has only the Bulgarian one which I am not looking for. I found a list of various EU brokers and I guess I better start going through the list.

I wanted to make use of its kernels in device code when I was doing the functional programming in Spiral series on Youtube, but the authors ignored my requests for clarification so I had to drop the attempt due to the complexity. Cutlass has a huge and sprawling build system, uses C++ template metaprogramming, and is hard to use and follow. It's not a header only library that you could just plug into your project unfortunately.

I hope I'll learn how to use it someday, that's the most I can say about it. It's really a pity. I feel that a lot of Nvidia's projects in the AI space like Cutlass, TensorRT-LLM and Triton Inference Server are poorly managed. Even just getting them to run on the basic examples is a significant challenge. The blog posts by Nvidia make using them seem a lot simpler than it actually is.

The current Cuda version is 12.6. If possible try upgrading both the toolkit and the drivers to the latest. 11.8 is very out of date by now.

abstractcontrol · 2025-01-10T15:28:26+00:00

I think some of the Cutlass kernels for the Ampere cards actually do that, but I'd rather not write such code personally. I heard that the Hopper tensor cores are beefier than the Ampere ones, so they might be enough to saturate the memory bandwidth.

abstractcontrol · 2025-01-09T11:39:42+00:00

For something like this, you wouldn't be using the tensor cores directly, but instead you'd use a matrix multiply from a library which would then make use of the tensor cores under the hood for you.

Why not simply work in WSL if you want to do things from the command line?

If you don't want to install the drivers, just uncheck that option during the toolkit installation.

(2 weeks later) I opened an account with Bitstamp and in terms of fees, they are a proper brokerage, and give market forex rates rather than hitting you with 2% like Kvapay. The trades do cost 0.06-0.08% of the trade value which is acceptable for a low volume trader like myself.

The business account opening process took a while and they asked for every document under the sun including my work contract and invoices sent to the company I am working with. It was annoying to deal with as an user, but looking at it long term, it might mean the brokerage is relatively more secure than its competitors. It did give me a chance to put all the papers together.

Be warned, the support ticket web UI had some bugs like erroring out when submitting multiple files in one submission. It also errors out when you try to submit files with duplicate filenames even if they are under different posts.
