AI-native strategies · built in the open
Trading just got an
AI-native era.
Come build it with us.
Balder is an AI-native trading desk. An agent loop researches, tests and trades — reading filings, option chains and institutional flow at a scale no analyst team can match — and every position it takes is published, on entry and on exit.
Members get more than signals. You get the tools, the structure reads, the earnings radar, and the reasoning behind every call — so you learn how an edge gets found, not just what to buy. Three engines live. More every month.
Backdrop: cumulative per-trade return across 55 closed trades (07-31–08-15) — equal weight, a sum of trade returns, not a portfolio return.
Calls that worked
Balder’s Position — the four best, entry to exit
The top four closed positions from the long book. Gold marks where the book disclosed the entry, white where it announced the exit — and because both were published before the outcome was known, the full record, losers included, is one click away.

Balder’s Position
Uptrend trend-following, published after the close, entry and exit both disclosed.
See the record →Why this is different
Anyone can run a model. Almost nobody checks the inputs.
Most market coverage is a vendor feed with a chart on top. This desk reads the primary record and fixes what the feeds get wrong — which is where the edge actually lives now that everyone has the same models.
We read the filings, not a feed
The Q2 flow panel is rebuilt from SEC’s raw 13F data across 1,410 managers and 4.77M holdings — then corrected for stock splits, entity migrations, CUSIP changes and filer misreporting. Every one of those makes a vendor number quietly wrong.
Details other people get wrong
An earnings reaction lands on a different day for a pre-market reporter than an after-close one. Measure both alike — as most sources do — and a fairly-priced option looks 4× too expensive. Ours is session-aligned.
Upstream of the news
Form 4 insider buys and 13D stakes are pulled straight off EDGAR twice a day, filtered to open-market purchases with the insider’s own cash. The filing is public before anyone writes it up.
The loop keeps compounding
The research agent runs continuously — testing ideas, killing the ones that fail, and promoting what survives. Three engines live today. The ones that reach the site are the ones that already earned their place.

Markets around the clock
The market closes.
The world doesn’t.
Friday 4pm the tape stops, and for 65 hours every app you own shows you a dead number. Meanwhile Tokyo trades, futures move, and by Monday’s open the gap has already happened — you just weren’t allowed to watch it.
Track the market when the market is shut
This one forecasts nothing. It is a live board that never goes dark: cash index during US hours, CME futures overnight, and Hyperliquid perps at weekends — so there is a real price at 3am on a Sunday instead of a stale Friday close. Every number is an actual print from a named venue. Only tickers with a genuine 24/7 venue appear; nothing is invented to fill a gap.
- Indices — SPX and NDX: cash in RTH, CME futures (ES/NQ minus basis) overnight, Hyperliquid US500/USTECH perps at weekends.
- Single stocks — 13 names with a real round-the-clock venue: US consolidated print 4am–8pm ET, then builder-dex perp marks overnight, validated to track spot within about 1%.
- No fabricated quotes — if a name has no genuine overnight venue, it is simply not on the board.
SPX forecast
Tomorrow’s probability cone
A forecast, and deliberately separate from the 24/7 board — that one reports prints, this one puts a distribution on tomorrow’s close. Six thousand Monte-Carlo paths, gamma-adjusted, anchored on the live option chain: where dealers damp or amplify moves, and the walls that tend to pin price.
LAST SESSION · 2026-08-14
A 68% band that contains the close 94% of the time is too wide, not “94% accurate”. The honest read is that the cone is currently conservative, and tightening it is open work. We publish the number either way.
Every session on the ledger

What the option market charges vs what the stock does
Published every Sunday for the week ahead. For each name reporting, the board compares the implied move priced into options against the typical move that stock has actually delivered on its last nine reports. When those two disagree, that is the trade.
This week's board
Live predictions for the coming week, published before the reports. Verdict is the ratio of implied to typical: RICH means options cost more than the stock usually moves, CHEAP means less.
| Symbol | Reports | Session | Implied | Typical | Verdict | Up-rate | Window |
|---|---|---|---|---|---|---|---|
| HD | 08-18 | pre | 4.2% | 2.0% | RICH 2.10× | 56% | this week |

Previous predictions, scored
On every card the conclusion sits in the top-right badge — that is the whole read, and it comes in three colours: ■ green BULLISH means the model expects up, ■ red BEARISH expects down, and ■ grey coin-flip means it has no edge and makes no call at all.
Only the red and green calls are counted below — the same threshold the card itself uses to print the badge, so the table can never disagree with the picture. The grey ones are not predictions and are excluded rather than quietly scored as free wins — a call the model declined to make cannot be right or wrong. Click any row to see the original card exactly as it was posted on X, before the report.

How it's built
- Implied — the at-the-money straddle on the first expiry after the report, over spot. That is literally what the market charges you to own the move.
- Typical — mean absolute reaction across the last 9 prints, from the tape.
- Session alignment — a pre-market report moves the stock that day; an after-close report moves it the next. Measure both the same way and a fairly-priced option looks 4× too expensive. Most sources do exactly that.
- Silent weeks — if fewer than two covered names report, no board is published rather than padding one out.
Structure Read
The chart the desk actually trades from
Not a price line. Zig-zag pivots, the break triggers on both sides, measured targets, the volume-at-price magnet profile on the right edge, and the read written out underneath. 6 names below are the full desk chart; all 76 covered tickers are searchable.
Research
Institutional flow · Q2 2026
Rebuilt from SEC's raw 13F filings rather than a vendor feed. Net flow is change in share count × quarter-end price — change in reported value just tells you the stock went up.
- Splits restated from the holders themselves, not a data feed.
- Entity migration excluded — a manager re-registering is not buying.
- CUSIP changes and share classes netted by issuer.
- Misreported rows dropped against the filers' own consensus price.
Filing dredge · who got the $100B
SEC filings are the original record, public before anyone writes them up. This study read 124 companies' own 10-Qs to find where the struck-down tariff refunds actually landed.
- Form 4, code P only — an open-market purchase with the insider's own cash. Grants, option exercises and scheduled 10b5-1 sales say nothing about conviction.
- Schedule 13D — somebody crossing 5% with intent to influence.
- Scanned twice a day, straight from EDGAR full-text.

The short book — you see what it buys
Positions last from a few hours to a few days. Entries, adds and exits are reported as they happen, and half an hour after the close one card sums up every trade of the day — not the good ones picked afterwards, all of them.
Two strategies, run independently
They are trying to do different things, so they never interfere with each other.

Every closed trade
Newest first. The record is complete because each entry was published before the outcome was known.

Balder’s Position
The long book — every name, in and out
Uptrend trend-following. Published after the close, so you can take it in the after-hours session or the next morning — the holding period is long enough that the first few minutes do not decide the trade. Every position carries its reasoning.
Disclosed on the way in and on the way out — which is why the table below is complete by construction. There is no version of it with the losers removed.

How to use the subscription
Three channels, identical content — pick whichever is easiest. If you subscribe on X, do it in a web browser: subscribing inside the iOS app adds Apple's 30% cut.
1 · Balder-algo-logs — the short book
Close to a follow-along feed: you see what it buys, as it buys it. It runs two strategies, oversold bounce and momentum, holds from a few hours to a few days, reports every trade live, and posts one summary card half an hour after the close.
The two strategies run independently and never interfere — they are trying to do different things. Every closed trade is here →

2 · Balder’s Position — the long book
Uptrend trend-following. It goes out after the close, so you can trade it in the after-hours session or the next morning — the horizon is long enough that the first few minutes do not decide it. Every position comes with its reasoning and analysis; ask if any part of it isn't clear.
Disclosed on entry and on exit, so the record is complete — winners and losers both. See the record →

3 · Earnings Radar
The badge in the top-right corner is the whole read:
Green — the model expects up
Red — the model expects down
Grey — coin-flip, the model is
making no call at all
Grey does not mean "unsure". It means the model declined to act, and those are excluded from the record rather than scored as free wins. The scored history is here →

Trade with Balder
One price, three ways to pay, identical content on every one of them — the marked book, the cone, the radar, and the reasoning behind each call. What you get, in detail →
Also on X at $5 (subscribe on the web, not in the app — the app adds Apple's 30%) and Substack at $10. All three carry identical content. Full handbook →
- Send $10 for each month you want on Venmo — $30 gets you three.
- Put your email address in the payment note. That is the only way we know where to send you.
- The system reads the payment and enrols you automatically — usually within half an hour, no forms.
