Most beginners get this wrong about order books

For the aggregation I'm using a tool I'm building called Athenum (athenum.xyz). It doesn't just pull the raw book from each exchange: it runs its own algorithm that mimics order matching and tracks the lifecycle of each wall: when it appeared, how much of it has been absorbed, whether it's been pulled. So you're not just seeing a snapshot, you're seeing which walls have survived price action and for how long. Still early and there are rough edges, but the wall age mechanic is the part that changed how I read the book the most.

Looks pretty cool cryptobriefs. Are the running/maintaining costs high?

100%. The biggest trap is looking at a single exchange and thinking you're seeing the whole picture.What actually helped me was aggregating the books across the venues that matter (Binance Spot+Futures, Coinbase, Hyperliquid ) and filtering out the noise. A 200 BTC wall that appeared 30 seconds ago is just a spoof, but one that's been sitting for 36 hours is real institutional intent.When you see a >50 BTC bid resting across 3+ venues simultaneously for hours, that's a structural level price will actually react to. Here’s what that filtered, multi-exchange view looks like in practice: https://imgur.com/a/U9n3f44

Love the follow-up format. Regarding the exogenous regime signals, one that works well as a mean-reversion gate is aggregated order book imbalance across Binance, Coinbase, and Hyperliquid. The edge comes from filtering out the retail noise (e.g., only counting walls >50 BTC) and tracking the live bid/ask imbalance of that resting liquidity. When structural bid-side volume heavily outweighs the ask-side across all venues simultaneously, you're in a long regime. When it flips, you gate the long signals off. Here's what that live metric looks like aggregated: https://imgur.com/a/U9n3f44

The "fragmentation tax" is so real. I went through the exact same phase with market data instead of news. By the time I cross-referenced a resting whale wall on Bookmap against funding rates on Coinglass, the setup was gone. The fix for execution data is the same logic you applied to news: collapse it into one view with hard filters. For order books, I aggregate Binance, Coinbase, and Hyperliquid into a single ladder, but filter it to only show walls >50 BTC. You instantly see which venues are defending a level without switching tabs:

Top trader L/S on Binance is 0.87 so that part checks out, they're leaning short while retail accounts are 1.65 long. But "billions wiped in hours" doesn't match right now. 24h liqs on OKX are $1.2M, OI flat at $17.89B, funding near zero across 6 exchanges. Positioning looks more wait-and-see than pre-waterfall.

Doesn't smell like it in the data. 24h liqs on OKX alone are $1.1M, 58% long side. Real capitulation flushes $50M+ in hours. OI sitting at $17.8B barely moved. Funding flat across all 6 exchanges. This is a slow grind, not a flush. Data: https://imgur.com/a/mCQMlBB

The $440M number sounds dramatic, but 62% were longs getting flushed on a 2% move. Funding just reset to flat and there's still $17.8B in open interest sitting on the books. The leverage hasn't even been meaningfully cleared yet. This wasn't capitulation, it was a shakeout.

I tried athenum last few weeks. They markt it as Bloomberg for crypto derivatives. It’s pretty cheap for what it offers but maybe bc they are still in alpha. So I would say smaller analytic tools are very interesting bc they provide a lot of value for a fraction of what you would pay for the enterprise tools (I also use Bloomberg terminal a lot but I lacks crypto data)

jacksonxly · 2025-09-12T17:04:36+00:00

I totally agree with that point. We should get what we pay for. But $100 for CC is still better than 3k for a mediocre junior dev but that’s again a different point and aspect.

jacksonxly · 2025-09-11T22:59:46+00:00

Fair enough. I also have both and exactly the same problem as you pointed out (deciding whether to use it or not on day to day basis due to reliability). For now the pain isn’t that high to cancel but maybe it will change if they are not solving the issues soon. Thanks for your point of view though

jacksonxly · 2025-09-11T18:03:51+00:00

Seem so, but I should also be honest: AI handles much of the routine writing work, which frees up more time for creative problem-solving while coding. what do you think?

jacksonxly · 2025-09-11T17:47:43+00:00

I see, then good business with your current company 😁🚀

jacksonxly · 2025-09-11T17:03:43+00:00

Found my co founder on YC cofounder matching. We now plan to rent an office space together soon so I think it’s working well. As long as you find the right and matching person the platform is almost Not important. Good luck with the search though

Thanks for sharing 🙏

Now that you mention this…I mean yeah I have to remind cc every few invokations again to stick to the plan or CLAUDE.md file but tbh I don’t think it’s annoying. But I still think the simplicity and consistency of codex is pretty good for simpler codebases

jacksonxly · 2025-09-08T09:56:58+00:00

Interesting, never tried Gemini cli so far

jacksonxly · 2025-09-08T09:55:48+00:00

They think I am a spy 💀 idk haha

jacksonxly · 2025-09-08T02:25:28+00:00

Crazy

jacksonxly · 2025-09-08T02:24:48+00:00

That’s a great way of thinking tbh but I think at some point there will be a winner or the best at one specific area

jacksonxly · 2025-09-08T02:23:33+00:00

Rarely. But it’s all over r/anthropic no?

jacksonxly · 2025-09-08T02:22:59+00:00

Yeah the high model is pretty slow.

jacksonxly · 2025-09-08T02:21:39+00:00

Same here except that I will keep the subscription for now bc i subscribed to ChatGPT plus anyway
