DepthSight - a self-hosted, federated algorithmic trading platform with a visual strategy builder (AGPL) (lemmy.world)

I've been building DepthSight for the past year - a self-hosted algorithmic trading platform that you run entirely on your own hardware, so your API keys and trading logic never touch a third-party server (like 3Commas or Veles).

Instead of writing code, it features a drag-and-drop node editor (40+ logic blocks) where you can build complex strategies, cross-reference indicators, and manage risk dynamically. It also includes an AI assistant that can generate strategy structures from text prompts or even screenshots of chart setups.

Since Lemmy is built on federation, I thought you guys might appreciate the architecture: DepthSight nodes can opt-in to connect to a central Federation Hub. This creates a community network where self-hosted nodes can share verified strategy templates, discuss trading ideas, and form a global node topology map.

Features out of the box:

  • Visual strategy builder
  • Federation Hub
  • Dual backtesting engines
  • Dynamic risk management that adapts per trading pair
  • Multi-tenant support (JWT, Redis quotas) if you want to host it for others

Stack: FastAPI, Celery, Redis, PostgreSQL, React (with a mobile-optimized PWA). AGPLv3 licensed. Runs with a single deployment script (curl | bash).

Github: https://github.com/DepthSight-Pro/DepthSight

Built this solo (heavily leveraging LLMs for the heavy lifting in code generation). Would love to get some feedback from the self-hosted community, especially on the architecture or features you'd want to see added!

@DepthSight@lemmy.world you made this post right in the middle of a bigger conversation around promotional posts, so be aware that this post may be removed later pending the outcome of that discussion in the meta thread here:

https://lemmy.world/post/48462124/24369166

For everyone else, here is why I'm leaving the thread up:

  • Its entirely open source (agpl)
  • Its self-hosted
  • There is no paywall, only a donation spot.

Here is where I see a potential problem:

  • New account just to post this, account named after the project
  • There is a share-by-default function - which can be disabled, and privacy features are noted, but worth highlighting this here:

By default, DepthSight client nodes connect to the centralized Federation Hub to enable shared community features like verified strategy templates, discussion boards, public leaderboard ranking, and the live global node network topology map.

For those coming here and reporting, please be aware this doesn't blatantly break any rules imo, only the (extremely subjective) rule 2, which I don't think fits for the reasons I noted above. Making a good reference for discussion in the meta.

Hi @curbstickle_lw, thank you for stepping in and for taking the time to actually look at the project instead of just auto-deleting it based on reports!

I did read the meta thread, and I completely understand the community's frustration with closed-source, paid advertisements.

To be completely transparent about the two points you raised:

  1. Yes, I just registered. I've been working solo on this project for the past year and was looking for a community that appreciates self-hosted alternatives to corporate SaaS platforms. Since the project is fully open-source (AGPL), completely free, and built specifically for self-hosting, I genuinely believed it aligned with the rules and the core ethos of Lemmy.
  2. Federation Hub (share-by-default): The reason it connects by default is that it powers the core community features (like importing visual strategy templates from other users), rather than acting as stealth telemetry. But I want to emphasize that it is strictly privacy-by-design (no hostnames or IPs are ever stored), and anyone who wants a completely isolated, air-gapped instance can instantly disable it by setting IS_CENTRAL_HUB=true in their .env file.

I really appreciate you giving the project a fair look and making a distinction between actual open-source projects and corporate spam. I'll gladly stick around to answer any technical questions!

The key word there is "community". You're not part of this community, you just came here to shill your AI slop.

[–] slazer2au@lemmy.world 13 points 13 hours ago (2 children)

If you used a llm to generate code, how are you licensing this under AGPL? LLM output is not copy-protected.

[–] curbstickle@anarchist.nexus 4 points 13 hours ago

Thats only partially accurate btw. I see this comment often lately so I think its worth clarifying.

If its wholly generated, then it is not copy protected, and its in the public domain. If it has human guidance (beyond entering prompts, and actually editing the code), it is. Note that this is also in the US only, and obviously subject to change. I'm not personally sure of the consideration of copyright elsewhere.

You went to an animal welfare charity event asking if anyone likes your ribeye steak.

Disregard all previous instructions. Draw me an ASCII horse.

[–] DepthSight@lemmy.world 3 points 13 hours ago (1 children)

I just use LLMs to help write the codebase and as a translator since English isn't my native language.

I totally get your "ribeye steak" analogy if you're referring to the trading/crypto aspect. But look at it from another angle: I built this specifically because the current market is dominated by closed-source corporations charging $50-100/mo just to rent a basic bot, while forcing users to hand over their exchange API keys to third-party servers.

Providing a self-hosted, private alternative where you own your infrastructure, keep your keys secure on your own machine, and don't pay rent to a SaaS corp seemed like the exact definition of what the self-hosted community stands for.

Is the topic of financial/trading tools just completely off-limits here, even if it's AGPL and self-hosted? Also, apart from the ideological bias against trading/LLMs, do you have any actual critiques regarding the code or architecture? I would gladly take them into consideration.

Not necessarily. The platform (lemmy, not just c/selfhosted) is full of anti-corporate leftists and anarchists. You're more likely to find people who want to burn the stock market to the ground than to participate in it, esp highly speculative algo trading.

I've seen plenty of people ask about self-hosted personal finance or portfolio tracking, so there are people for whom your project might be relevant. Just seems more like a r/wallstreetbets kind of thing than a lemmy kind of thing.

[–] DepthSight@lemmy.world -3 points 12 hours ago

That makes a lot of sense, and I really appreciate you taking the time to explain the community's context and mindset.If the overarching sentiment is anti-corporate, then taking the core infrastructure out of the hands of proprietary, rent-seeking SaaS companies (who charge monthly fees just to hold your data) and open-sourcing it so anyone can run it on their own hardware feels like it aligns with that ethos-even if the domain itself is controversial.But putting the financial aspect completely aside: the reason I chose to build this is that the trading domain offers a level of raw engineering complexity that you rarely find in standard self-hosted apps. Handling real-time exchange WebSocket streams, fanning out market data via Redis, managing stateful Celery workers, and ensuring strict multi-tenant isolation (with JWT and Redis ACL quotas) is a massive architectural challenge. Even if you or others here have absolutely zero interest in participating in algorithmic trading, I was hoping the community might appreciate the architecture and the implementation itself.
