# Seven-venue BTC volume share and realised volatility, one week -- mcp side

## Question
Venue share and realised vol. For BTC perpetuals on Hyperliquid, edgeX, ApeX, Pacifica, dYdX, Paradex and Nado over 2026-09-21 00:00 to 2026-09-28 00:00 UTC: each venue's total traded notional in USD and its share of the seven-venue total; and each venue's realised volatility of 1-minute log returns, annualised. Is realised vol consistent across venues? If not, explain the outliers.

## System prompt
You are an agent assisting a quantitative researcher. Work the question end to end: find the data, compute, check your own numbers, and make the judgement calls a careful quant would make. You have a Bash tool; Python 3 with duckdb, pandas, pyarrow and numpy is at /tmp/peerfeed-a21/venv/bin/python. Work inside your current directory. When you are done, end with a section headed FINAL ANSWER that gives every number asked for and states each judgement call you made. Your only source of market data is PeerFeed's market-data MCP server (the tools named mcp__peerfeed__*). There is no market data on local disk.

REQUIREMENTS FOR SUMMARIZATION/ANALYSIS/REVIEW:
- You MUST read the content from the file at ~/.claude/projects/-tmp-peerfeed-a21-work-t3-mcp/cdc88b4c-5171-46e8-b792-fc6d2e293f63/tool-results/mcp-peerfeed-list_instruments-1790712749988.txt in sequential chunks until 100% of the content has been read.
- If you receive truncation warnings when reading the file, reduce the chunk size until you have read 100% of the content without truncation.
- Before producing ANY summary or analysis, you MUST explicitly describe what portion of the content you have read. ***If you did not read the entire content, you MUST explicitly state this.***
- If after a few attempts you cannot read the file (file not found, lines too long for Read's offset/limit, no shell access), STOP retrying. Summarize what you were able to read, explicitly state which portion you could not read and why, and proceed.

AMENDED 2026-09-28: `absent` now CARRIES TWO PROVENANCES; read the `reason` field, never the kind alone. reason absent/implicit = the 2026-07-27..09-19 sweep described above. reason='recorder_parse_failed' = the recorder could not parse the exchange's frames, so nothing was ever written to L0 either and the loss is permanent and unrebuildable -- established for paradex/trades and paradex/bbo 2026-09-19..09-27 (Paradex moved to SBE binary framing; the JSON parser failed every frame; unified-recorders #199, recording resumed 2026-09-28 14:07 UTC). The distinction is load-bearing: a sweep-absent day may still exist on a peer, a parse-failed day exists NOWHERE, so one says look elsewhere and the other says stop looking. ⛔ CORRECTED 2026-09-28: the paradex range stated above as 2026-09-19..09-27 IS WRONG and was never measured by its author (mission-2) -- it was relayed and accepted. Measured file-by-file on all three hosts and the NAS by market_data_mcp, confirmed independently: the fleet-wide stop is 2026-09-22 04:26:53.116 UTC (trades) / 04:31:32.090 UTC (bbo), NOT 09-19. 2026-09-19 is on both peers AND ON THE NAS -- it is missing only from nm's local tree, so labelling it absent would tell a consumer to stop looking for a day the archive holds. 2026-09-20 and 09-21 are FULL days present on all three hosts and absent only from the NAS: that is not_archived / reason='not_yet_processed', owed by mission-2, NOT absent. The emitted paradex labels (42, market_data_mcp, as_of 2026-09-28T14:54:55Z) correctly start at 09-22 and are the authority; this note previously contradicted them. THIRD PROVENANCE, added 2026-09-28: reason='recorder_filter_dropped' -- a day on which filter_unchanged discarded EVERY record because no recorder restart occurred, so the retained subset is empty. Nothing was ever written to L0 (the filter runs before the write), so `absent` is literally accurate and permanent. It is deliberately NOT `biased_subset`: that kind promises rows exist but are unrepresentative, and a consumer selecting datasets with usable rows would wrongly include a zero-row day. The two kinds are the same defect at different amplitudes -- mexc/funding_rate has 159 biased_subset days and ~106 zero-retention days in 2025-12-30..2026-09-20 -- so a zero day's `detail` must name biased_subset so the halves are joinable. ⚠ COUNTS ARE LABELS, NOT LOSS (flagged 2026-09-28 by market_data_mcp, whose labels they are). `emitted_counts_at_as_of.absent` = 293 includes 95 mexc/funding_rate zero-retention days, and those days NEVER HELD ROWS TO LOSE -- the loss they belong to is the 168 `biased_subset` days plus whatever the filter discarded on the 95, which is UNMEASURABLE because the discarded records were never written anywhere. So summing `absent` as a loss figure inflates it. This generalises to every kind: the counts measure how many labels have been WRITTEN, which is a fact about how much looking has been done, not about how much data is gone. The `reason` field prevents the misreading; a bare total invites it.",
      "partial_window": "per-shard coverage for 2026-09-15/09-16/09-17 00-02..12-14 at ~0.26. Other days were not measured for windowed loss. AMENDED 2026-09-28: also carries basis='recorder_resumed_midshard' for the shard in which a recorder resumed after a permanent gap -- paradex/trades and paradex/bbo 2026-09-28 14-16. The original basis is basis='window_built' (generator cutoff). Read `basis`, not the kind. A resumed-midshard coverage_fraction must be MEASURED; where it is not, write UNMEASURED rather than deriving it from the resume timestamp, because the feed's rate across the boundary is unknown. That record must also carry `join_hazard`: paradex trade `id` changed format across the gap -- 28-digit string before 2026-09-19, str(int64 trade_id) from 2026-09-28 -- so cross-gap joins on `id` are INVALID. That is a value-format discontinuity, not a `type_widened` promotion; it is a field rather than a kind because one instance does not earn vocabulary. If it recurs, it does. ALSO 2026-09-28: basis='recorder_stopped_midshard' for the shard in which a recorder STOPPED (the mirror of recorder_resumed_midshard) -- paradex/trades 2026-09-22 04-06 (feed died 04:26:53.116 UTC) and paradex/bbo 2026-09-22 04-06 (04:31:32.090 UTC). Same rule: MEASURE coverage_fraction against an adjacent healthy shard, or write UNMEASURED; the feed's rate across the boundary is exactly what must not be assumed from the stop timestamp. ⛔ ENCODING CORRECTED 2026-09-28, market_data_mcp's design accepted over mine: `basis` names WHAT THE FRACTION IS A FRACTION OF (e.g. 'window_spanned', 'window_built'), and the CAUSE goes in `reason` ('recorder_stopped_midshard', 'recorder_resumed_midshard'). I had registered the cause as `basis`, which overloads the one field a consumer needs to decode 0.224 and makes the number uninterpretable. Measured vindication of the measure-don't-derive rule: for paradex 09-22 04-06 the window axis gives trades 0.2240 / bbo 0.2628 against healthy baselines of 0.9742-0.9914, while a ROWS ratio would have said 0.53 for bbo -- twice the truth -- because the same shard holds 185, 233, 318 and 553 rows across four HEALTHY days, a 2.4x spread, so a rows ratio reports trading rate as coverage. paradex 09-28 14-16 is DEFERRED, not missing: L0 exists from 14:08 UTC but no parquet has been generated, and a label over bytes nobody has written would assert coverage of nothing."

Most venues look clean. There are two problems: edgeX returned no bars for the window, and Paradex has lost most of its data. I'll look into edgeX first.

EdgeX volume mirrors Hyperliquid's pattern with no signs of duplication, but ApEx's flat ~$300M daily volume, even on weekends, looks suspicious. Next I'll check Paradex and dYdX for volume outliers by comparing their minute closes against Hyperliquid's.

AMENDED 2026-09-28: `absent` now CARRIES TWO PROVENANCES; read the `reason` field, never the kind alone. reason absent/implicit = the 2026-07-27..09-19 sweep described above. reason='recorder_parse_failed' = the recorder could not parse the exchange's frames, so nothing was ever written to L0 either and the loss is permanent and unrebuildable -- established for paradex/trades and paradex/bbo 2026-09-19..09-27 (Paradex moved to SBE binary framing; the JSON parser failed every frame; unified-recorders #199, recording resumed 2026-09-28 14:07 UTC). The distinction is load-bearing: a sweep-absent day may still exist on a peer, a parse-failed day exists NOWHERE, so one says look elsewhere and the other says stop looking. ⛔ CORRECTED 2026-09-28: the paradex range stated above as 2026-09-19..09-27 IS WRONG and was never measured by its author (mission-2) -- it was relayed and accepted. Measured file-by-file on all three hosts and the NAS by market_data_mcp, confirmed independently: the fleet-wide stop is 2026-09-22 04:26:53.116 UTC (trades) / 04:31:32.090 UTC (bbo), NOT 09-19. 2026-09-19 is on both peers AND ON THE NAS -- it is missing only from nm's local tree, so labelling it absent would tell a consumer to stop looking for a day the archive holds. 2026-09-20 and 09-21 are FULL days present on all three hosts and absent only from the NAS: that is not_archived / reason='not_yet_processed', owed by mission-2, NOT absent. The emitted paradex labels (42, market_data_mcp, as_of 2026-09-28T14:54:55Z) correctly start at 09-22 and are the authority; this note previously contradicted them. THIRD PROVENANCE, added 2026-09-28: reason='recorder_filter_dropped' -- a day on which filter_unchanged discarded EVERY record because no recorder restart occurred, so the retained subset is empty. Nothing was ever written to L0 (the filter runs before the write), so `absent` is literally accurate and permanent. It is deliberately NOT `biased_subset`: that kind promises rows exist but are unrepresentative, and a consumer selecting datasets with usable rows would wrongly include a zero-row day. The two kinds are the same defect at different amplitudes -- mexc/funding_rate has 159 biased_subset days and ~106 zero-retention days in 2025-12-30..2026-09-20 -- so a zero day's `detail` must name biased_subset so the halves are joinable. ⚠ COUNTS ARE LABELS, NOT LOSS (flagged 2026-09-28 by market_data_mcp, whose labels they are). `emitted_counts_at_as_of.absent` = 293 includes 95 mexc/funding_rate zero-retention days, and those days NEVER HELD ROWS TO LOSE -- the loss they belong to is the 168 `biased_subset` days plus whatever the filter discarded on the 95, which is UNMEASURABLE because the discarded records were never written anywhere. So summing `absent` as a loss figure inflates it. This generalises to every kind: the counts measure how many labels have been WRITTEN, which is a fact about how much looking has been done, not about how much data is gone. The `reason` field prevents the misreading; a bare total invites it.",

AMENDED 2026-09-28: also carries basis='recorder_resumed_midshard' for the shard in which a recorder resumed after a permanent gap -- paradex/trades and paradex/bbo 2026-09-28 14-16. The original basis is basis='window_built' (generator cutoff). Read `basis`, not the kind. A resumed-midshard coverage_fraction must be MEASURED; where it is not, write UNMEASURED rather than deriving it from the resume timestamp, because the feed's rate across the boundary is unknown. That record must also carry `join_hazard`: paradex trade `id` changed format across the gap -- 28-digit string before 2026-09-19, str(int64 trade_id) from 2026-09-28 -- so cross-gap joins on `id` are INVALID. That is a value-format discontinuity, not a `type_widened` promotion; it is a field rather than a kind because one instance does not earn vocabulary. If it recurs, it does. ALSO 2026-09-28: basis='recorder_stopped_midshard' for the shard in which a recorder STOPPED (the mirror of recorder_resumed_midshard) -- paradex/trades 2026-09-22 04-06 (feed died 04:26:53.116 UTC) and paradex/bbo 2026-09-22 04-06 (04:31:32.090 UTC). Same rule: MEASURE coverage_fraction against an adjacent healthy shard, or write UNMEASURED; the feed's rate across the boundary is exactly what must not be assumed from the stop timestamp. ⛔ ENCODING CORRECTED 2026-09-28, market_data_mcp's design accepted over mine: `basis` names WHAT THE FRACTION IS A FRACTION OF (e.g. 'window_spanned', 'window_built'), and the CAUSE goes in `reason` ('recorder_stopped_midshard', 'recorder_resumed_midshard'). I had registered the cause as `basis`, which overloads the one field a consumer needs to decode 0.224 and makes the number uninterpretable. Measured vindication of the measure-don't-derive rule: for paradex 09-22 04-06 the window axis gives trades 0.2240 / bbo 0.2628 against healthy baselines of 0.9742-0.9914, while a ROWS ratio would have said 0.53 for bbo -- twice the truth -- because the same shard holds 185, 233, 318 and 553 rows across four HEALTHY days, a 2.4x spread, so a rows ratio reports trading rate as coverage. paradex 09-28 14-16 is DEFERRED, not missing: L0 exists from 14:08 UTC but no parquet has been generated, and a label over bytes nobody has written would assert coverage of nothing."

## [agent]
Across the seven venues, BTC perps traded about **$28.27B** in the week, and Hyperliquid had **73.8%** of it. Paradex's figure is **not a week's volume**: our recorder lost Paradex from 2026-09-22 04:26 UTC to the end of the window, so only about 28.4 of 168 hours exist. Realised vol **agrees across venues (about 36–38% annualised)** except for dYdX and Paradex. Both are high because thin trading adds noise to their prices, not because BTC moved differently there.

The server only gives 1-minute bars, and it drops any minute with fewer than 3 trades. It reports how much volume it dropped, so I added that back to each venue's notional at the week's average price. The adjustment only matters for Pacifica (+$13.9M), dYdX (+$2.3M), Nado (+$1.1M) and Paradex (+$0.4M).

**Where the data needed care**
- **edgeX:** the old `BTCUSD` contract stops in mid-August, so I used `BTCUSDC` instead. Its daily volume moves with Hyperliquid's, so the "possible duplication" warning on 09-21 doesn't hold up.
- **Nado:** its BTC perp is product id `2` (price about $84.6k). Its timestamps are when our recorder saw each trade, not the exchange's own time.
- **Paradex:** the missing data is logged as permanent: the exchange changed its message format and the recorder could not read it. It can't be recovered.
- **ApEx:** the data is complete but looks odd. It trades a flat $270–324M every day, even on the weekend when Hyperliquid fell to $0.9B, with larger average trades ($12.7k against Hyperliquid's $8.7k). That looks like incentive or wash volume rather than organic flow.

**Why dYdX and Paradex are outliers**
- **dYdX:** only 1,885 of 10,080 minutes have a bar, and only 774 of those are back-to-back. Its minute closes are more scattered around Hyperliquid's (6.96bp vs about 4.4bp elsewhere), and on so little trading that inflates vol. Sampled every 5 minutes it falls to 0.40–0.43, close to the others.
- **Paradex:** two causes.
  - **Busier window:** its 28 hours fall on the most volatile part of the week. Hyperliquid's own vol over the same hours was 0.519.
  - **Off-market prints:** tiny trades far from the market, for example 0.0006 BTC at 87,711.6 when Hyperliquid was around 86,400 (+154bp), and one print 207bp below. It has 16 one-minute moves above 50bp, against 1–3 at the other venues.

  At 5 minutes over its own window it measures 0.54–0.58 against about 0.50 at the other venues, so the rest is noise.
- **Pacifica** is slightly high at 1 minute (0.438) because 30% of its minutes are thin; at 5 minutes it is 0.376.

# FINAL ANSWER

**Notional and share, 2026-09-21 00:00 to 2026-09-28 00:00 UTC**

| Venue (instrument) | Notional (USD) | Share of 7 | Share of 6 (without Paradex) |
|---|---|---|---|
| Hyperliquid (BTC) | $20.872B | 73.83% | 73.86% |
| edgeX (BTCUSDC) | $2.993B | 10.59% | 10.59% |
| ApEx (BTCUSDT) | $2.106B | 7.45% | 7.45% |
| Pacifica (BTC) | $1.384B | 4.90% | 4.90% |
| Nado (product 2) | $0.847B | 3.00% | 3.00% |
| dYdX (BTC-USD) | $58.6M | 0.21% | 0.21% |
| Paradex (BTC-USD-PERP) | $10.9M (~28.4h only) | 0.04% | — |
| **Total** | **$28.271B** | | **$28.260B** |

**Realised vol, annualised** (√(mean r²×525,600) on back-to-back 1-minute log returns of the closing price)

| Venue | 1-minute vol | Pairs of minutes used | Cross-check: 5-minute vol |
|---|---|---|---|
| Hyperliquid | 36.7% | 10,073 | 37.8% |
| edgeX | 36.5% | 10,077 | 37.2% |
| ApEx | 37.3% | 10,079 | 37.3% |
| Nado | 38.2% | 8,766 | 36.7% |
| Pacifica | 43.8% | 5,217 | 37.6% |
| dYdX | **88.5%** | 774 | 40–43% (43% when spanning gaps between trades, 40% trimmed) |
| Paradex | **123.7%** | 1,113 | 54–58% (other venues about 50% over the same hours) |

**Is vol consistent?** Yes for Hyperliquid, edgeX, ApEx and Nado (36.5–38.2%), and for Pacifica once sampled every 5 minutes. No for dYdX and Paradex, for the reasons above. Neither shows a real difference in how BTC moved.

**Judgement calls**
1. I used the current edgeX contract (`BTCUSDC`) and identified Nado's BTC perp as product `2` by its price.
2. Notional is Σ(volume × VWAP) from the bars plus the dropped volume valued at the week's average price.
3. I kept Paradex's partial data rather than extrapolating it. So its share is a lower bound, and I also give shares for the other six.
4. Vol uses only back-to-back minutes, with zero assumed mean return. I used 5-minute sampling and comparisons with Hyperliquid's price to separate noise from genuine price moves.
5. I flagged ApEx's volume as probably not organic but left it in the totals.
