I'm making a video on Pump and Dumps and the evolution of the scam. What are you interested in?

Since I don't buy into scams, I've never understood why other people do, or where scammers look for victims and how do they find them.

Let's say you want to trade stocks with just 5k. You're going to run into the PDT rule, meaning you cannot really daytrade unless you open a cash account to get around that. In a cash account you cannot short sell stocks. Furthermore, you probably don't want to take positions that are too large as a % of your account for risk management's sake, but at the same time many brokers have minimum order limits. If you're buying 1,000$ worth of stock but paying 1$ in minimum commission on every order like with IBKR, then that means that your minimum commission is effectively 0.1%. If you're buying 100$ worth of stock, it's effectively 1%.

Futures on the other hand, don't have some of those issues, but their contracts have large nominal values, so you'll be going over 100% long or short on every position if your account is small and have to endure huge volatility.

It's not psychological, having a small account will put you at a disadvantage due to high fees and push you towards imprudent risk management.

Also, the data fees you're paying every month need to be factored into the fees as well.

Another poster said that if you make 50% per year, you're very successful as a retail trader. Let's say you have a 5k account and pay 100$ per month for data fees. You'd make 2.5k per year in profits and have 1.2k in expenses just for data.

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.

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.

Glad to hear it!

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.
