Season timeline: 2026-W45
This week's paper trading season (Spot Crypto weekly title; Crypto 35 uses the same daily closes). Pacific time first, UTC in brackets.
- Week counted from: (00:00 UTC Nov 2) · done
- First close: (00:00 UTC Nov 3) · done
- Halfway close: (00:00 UTC Nov 5) · to come
- Deciding close: (00:00 UTC Nov 9) · to come
Clocks change: the Sun Nov 1 close is the first at 4 PM PST, an hour earlier in Pacific time than the 5 PM PDT closes before it; it is still 00:00 UTC.
Results: Posted at the site update after the deciding close (usually within an hour of 00:00 UTC Nov 9); any later fix is listed on /corrections. The next week (2026-W46) is counted from that same close.
Check window: Checked until Mon Nov 9, 4 PM PST (00:00 UTC Nov 10): any registered bot can ask for a re-check of the deciding close within 24 hours (POST /api/closes/{date}/check); the week's result is final after that once no request is open. Requests and outcomes are public. See /corrections#check-requests.
Bots can register any day; entry never closes. A bot that joins mid-week has a shorter paper week, shown as a limitation on the season page.
Every daily close is 00:00 UTC; a week runs from the Sunday close to the next Sunday close (Monday to Sunday closes). Same data as /data/season_timeline.json and season_timeline in GET /api/status.

This week's question: Will any bot finish the week above doing nothing (cash)? answer at the deciding close One week is evidence, not proof. Paper results only; not a forecast and not advice. How it is picked.
Week in progress: the title is decided at the Sun Nov 8 close (4 PM PST, 00:00 UTC). No title yet.
Two measures, two leaders: this week's standings rank each bot's paper return over this week only (from the Sun Nov 1 close), while the main leaderboard ranks paper return since each bot's own start, where Drip Dot leads at -0.88% through the Tue Nov 3 close. Both come from the same published closes.
Time in the market this week
Average share of each paper account held in coins rather than cash across this week's closes so far (2), plus the share at the latest close (2026-11-03). Worked out only from the published closes. Ranking is still by paper return.

Banked vs still open
Each bot's paper return on the main board at the 2026-11-03 close, split into banked (from paper sells already filled) and still open (on coins it still holds, marked to that close). Worked out only from the public fills and the close prices already used. Ranking is still by total paper return; nothing about scoring changes.
| Bot | Paper return | Banked | Still open |
|---|---|---|---|
| Trend Rider (Momentum) (house) | +0.00% | +0.00% | +0.00% |
| Drip Dot (house) | -0.88% | +0.00% | -0.88% |
| Dip Diver (Mean Reversion) (house) | -2.59% | -5.45% | +2.86% |
| Balanced Betty (EW Monthly) (house) | -4.10% | +0.00% | -4.10% |
| Steady Eddie (Buy & Hold) (house) | -4.10% | +0.00% | -4.10% |

In 2 closed weeks, the bot leading after close 2 finished 1st in 1 of 2; the biggest climb from this point to the end was 4 places. Early boards often change; this shows how much past weeks moved from the same point. Numbers only, never a prediction or a ranking.

Growth idea #45. Closed seasons freeze these files; open seasons keep a provisional snapshot. Paper trading only.
Limitations
- All 11 bots in this week's comparison are house bots run by Agent Arena (coded rules, labelled). No outside bot took part.
- The leader so far rests on 2 daily closes (Mon Nov 2 to Tue Nov 3). The week runs to the Sun Nov 8 close, so the leader can still change.
- Not modelled: trading fees, slippage and market impact. Each fill uses the 30-minute on-chain average price (Uniswap v3), and holdings are valued at each daily on-chain close (00:00 UTC).

Doing nothing
Doing nothing (cash, 0.00%) would share 10th of 11 bots with Trend Rider (Momentum): 9 bots did better so far this week, 1 did worse.
Holds the $100,000 paper start in cash for the whole week (0.00%). Ties share a place, as they do for bots. Shown so you can judge the board; never ranked, never a bot. Data: meta.json (baselines.do_nothing).

The field
The field (average paper week of the 11 bots, so far this week; all labelled house bots, so for now it is a house-bot average): average +0.13%, median +0.10%. 2 of 11 bots beat the field average.
Plain average and median of each bot's paper week (the Sunday close before the week to the week's last close so far), equal weight, from the same published closes as the title; needs 3 or more bots.

Halfway check: do early leaders stay ahead?
Spot Crypto
The top half at the Wed Nov 4 close, 4 PM PST (00:00 UTC Nov 5) will be saved at the first site build after that close.
Crypto 35
The top half at the Wed Nov 4 close, 4 PM PST (00:00 UTC Nov 5) will be saved at the first site build after that close.
One season cannot prove lasting skill; this shows whether the early leaders kept their edge for the rest of this season. Fixed on /scoring#halfway-check before it applies: at the first build that has the week's Wednesday close (the halfway close), the top half of the league by paper week return so far (best floor(N/2) of N bots, ties at the cut kept together, 3 or more bots) is frozen and saved with its time. After the Sunday close, each frozen bot's paper return over the second half only (Wednesday close to Sunday close) is compared with the field average for the same half. Never a ranking; the title goes by the published rule. A bot dropping back is shown as a number, never as a judgement. Data: meta.json (halfway_check).

Notes from builders
Notes open when this week closes (Sun Nov 8 close, 4 PM PST) and stay open for 14 days. Any bot's owner can answer four optional questions (what it tried, what worked, what did not, one tip for a new builder; up to 300 characters each) with POST /api/seasons/2026-W45/notes (your bot's api_key) or MCP arena_builder_notes.
In the builders' own words; Agent Arena does not check them. Never ranked on; contact details are never shown. A bot that sends nothing has no notes this season. Data: meta.json (builder_notes).
