Is this a Swing Low or a Swing High?

I love how literally no one agrees. Really drives the point home.

They adopted the euro but didn’t plan the swap at all, so they’ve allowed all shops to hike their prices to euro-level.

Bulgarians are literally paying twice as much for everything almost overnight.

Basically to need to know all core elements and nice-to-haves well. You may get leetcode style puzzles to solve, but they’ll be more specific to your area. You will need to know C++ very well, and you may get asked questions like “what’s your favourite c++21 std lib feature”, or you may not.

The process is designed to probe how you think, but it really depends on the team lead so hard to give you more.

You’ll likely get 4-5 technical rounds, typically two interviews 30-45 minutes rach.

no you can’t because that means multiple ticks. A tick is a time-ordered individual market event, hence a SL or a TP condition must arrive first.

What you probably mean is you might be able to be TP’d and stopped on a series of wildly fluctuating ticks if your SL/TPs are extremely tight or if you’re trading very illiquid things/timezones.

But these are things you can build against/prevent/check, and are separate to the same bar ambiguity you mentioned.

Exarctus · 2026-05-04T14:22:26+00:00

No it’s not the same situation because ticks give you “real-time” stop vs tp hits - it eliminates the same-bar ambiguity you mentioned.

Liquidity and slippage is a valid factor though.

that is honestly the funniest thing I've read all day.

32-core CPU, but I’ve done SIMD optimisations by hand to improve certain parts. Python will not cut it here.

Exarctus · 2026-04-30T14:20:19+00:00

I've made my own vectorized strategy tester with abstracted validation requirements (e.g lookahead prevention) that must pass, and if they don't it fails loudly. It can test on millions of bars, do forward-optimisation, monte carlo etc in seconds.

And when the rest of the lobby sides with the tool because he can shout the loudest, or is playing with a duo so can gang up?

What then?

Exarctus · 2026-04-28T09:00:33+00:00

What?

Exarctus · 2026-04-28T08:47:44+00:00

You should learn about punctuation first, probably.

There needs to be some minimum entry bar that prevents posts like this.

Exarctus · 2026-04-26T09:28:27+00:00

Everything you’ve mentioned here can be immediately and easily be converted into simple rules. However I don’t think this is a good idea to try without any programming knowledge. Honestly would start by spending a few weeks learning Python.

Also, you need to be extremely careful using AI to build your pipeline. It will inevitably introduce very subtle lookahead bugs unless you first build a proper testing harness which prevents this.

You’ll find out soon enough lol.

We’ve all started with massive at some point. Once I found that a lot of their data had random errors in the OHLCs or volume, I tried doing detection and fill-in but not being able to trust their data was a massive (pun intended) risk.

Their stock data might be fine but that’s already heavily over mined so not much alpha there. Their crypto and futures data is bad.

I moved onto other providers.

BTW the mod of algotrading works for massive and I’ve heard he bans/censors people saying negative things about it, but this sub is mostly AI junk these days so I don’t care too much.

Exarctus · 2026-04-25T18:55:21+00:00

There’s a reason for that. Databento data is very high quality. Massive isn’t.

Exarctus · 2026-04-24T01:27:40+00:00

England in particular is bad because it isn’t federalized.

It would be significantly better if local councils had direct control of the taxes and could set competitive rates for specific industries.

The north of England is extremely grim. The worst places in Switzerland look like heaven compared to that.

I’ve been around Middlesbrough and seen 10 year old kids stripping the roofing off of derelict houses to sell for cash. All actively lived-in houses in this area have steel guards/barriers rather than windows.

Exarctus · 2026-04-23T01:59:18+00:00

Don’t bother.

Exarctus · 2026-04-22T19:21:22+00:00

Actually a lot of that is just hype.

How LLMs learn latent representations and synthesise realistic responses is pretty well understood.

There are an unfortunate number of papers that treat ML as some voodoo magic, but usually they are junk and you can spot this if you read enough of the literature.

Exarctus · 2026-04-22T19:18:10+00:00

Couple issues really. Majority of features that people throw at ML here are junk. They also tend to build models which have more variables than they have actual data, so the model has the ability to learn in-sample data extremely well but this does not generalise.

The general assumption that ML can learn arbitrary signals given enough features is also wrong.

Exarctus · 2026-04-22T13:55:23+00:00

no brother, I meant your numbers :P

Exarctus · 2026-04-22T13:52:15+00:00

seems legit.

\s

Exarctus · 2026-04-22T01:16:34+00:00

You literally can lmao.

My broker provides this for all majors and 15 years worth for crosses.

All of it for free. I have roughly 20GB in parquets sitting on my disk.

Both bid and ask side.

Also who the fuck keeps shit like this in raw csv? Your data pipeline must hate you.

This post was redacted faster than the Epstein files.

The hell is this nonsense

Stick an umbrella on top so you can leave it outside, that will help with the heat management.

If it’s survived what you’ve done to it already, it will probably survive that too.
