It is both. We can use the same setup for both RL and Benchmarking.

Is it STRICTLY for LLMs & quant research or does it do generic trading simulation?

It is not only quant research. We also have live trading: https://edotenv.com/blog/long-horizon-planning

For now it is only facing LLM/Agent.

This is very cool, but who is the ideal customer here? I used to work at one of the top tier shops and we had multiple teams whose entire responsibility was building and maintaining our simulation environments.

We are selling to frontier labs, e.g. OAI and Ant, and fintech companies that are trying to build agentic trading system but do not have those internal quant setups, e.g. Coinbase, Kalshi etc.

You guys might want to look at Alphadidatic [0] and it might be worth your time to see if that model published 5 months ago still generalizes. Also, all the prompts are tuned for Claude 4.6 and I needed to throwout or rewrite all my agents, prompts, skills for Claude 5 which fortunately seems like it handles recursive self-improving agents natively.

I can't justify spending $1k - $2k a month for real time options data and compute for what is in my 401k. I guess the question I have is would your tool help me trade these strategies and more important test them on a few hundred a month?

Very interesting. I am curious: Is the "test" part actual live trading, or is it also a backtest?

I am asking because I see the agents can do websearch, so how is Alphadidatic preventing the agents from just looking at the asset's performances and cheat?

Back to our product. It is not 2C yet. So we are building the RL Envrionments for finetuning LLM, not providing a personal trading agent. However we can also build a professional trading harness using the setup we have. If you are interested, let's keep in touch: michael.zhang@edotenv.com

Strong agree that static evals saturate — the decay property of markets is the genuinely useful part: historically, quant alpha decays on the order of 30-50% per year as capital crowds in, so a live market eval is self-difficultating, exactly what model comparison needs once benchmarks plateau. The hard part I'd flag is comparability: market paths are stochastic, so two runs of the same model can land on wildly different difficulty depending on the realized path — without controlling for that, the eval measures luck more than the model. Options that work: fixed-seed regime paths with resampled baselines, or bootstrapped difficulty metrics (percentile of PnL against a distribution of random strategies) instead of raw return. The second hard part is reward shaping for RL: sparse PnL rewards over multi-day horizons give terrible exploration, so you'll likely need shaped intermediate rewards (execution quality, information state) to get gradients flowing at all. Also worth publishing: variance across seeds for each model — that's the number that tells users whether a 2% delta is signal or noise. Are you planning to ship fixed seed regimes, or is path stochasticity part of the point?

One thing I always think about whenever someone talks about solving investment is "and then what?" Say there's a crystal ball, wouldn't everyone use such crystal ball? Wouldn't crystal ball become illegal? Wouldn't crystal ball nullify the effects of things? What am I missing, can someone from this field educate me on how this stuff scales?

What's the margins that makes this worth chasing then? That's the part I maybe don't quite understand, why would you pour a lot of money and resources into something that is stochastic at best?

Quant trading is an extremely high margin business itself. Quant shops are printing billions and have on average much higher profits per employee than tech companies. So it is definitely a business worth doing. On the other hand, you could also view quant research as some very hard research problems, so training LLMs on these problems could also enhance their general research capabilities.

Right, that's quant trading, that's not this business. Enhancing their research seems like they are your customer and you would be eating from their margin.

How would you sell to them, you would deliver what? Faster time to decision? Wouldn't quants be your competition, given their work is building tools like this one?
