The engines

Built like a desk, not like a feed.

Each engine runs server-side on a schedule, banks its own history, and shows you what it measured — not what it thinks you should do.

Options Flow Diamond
Sweeps and blocks as they cross the tape, sized by premium with bid/ask side resolved. Every print written to permanent storage.
Dark Pool Prints Diamond
Institutional block trades off-exchange, with NBBO comparison and directional lean. Whale prints surface the moment they land.
Gamma Exposure Diamond
Dealer gamma by strike with the spot anchor marked, so you can read where price gets pinned and where it gets released.
Open Interest Scanner Diamond
Nightly OI deltas ranked by conviction, so you see where positioning actually built rather than where volume was loud.
Valuation Screeners Diamond
Undervalued, Re-Rating, Earnings Inflection and LEAP — four engines, each showing its formula and window instead of hiding behind a score.
Reversal Radar Gold
Exhaustion setups with the stop, target and ratio stated up front — and a measured outcome attached to every episode after the fact.
Options Chain Gold
Full chain with Greeks, volume outliers and long-dated LEAPS — built to be read, not squinted at.
Funding Stress Gold
Repo and SOFR against the corridor, credit spreads and the plumbing that seizes first when something is wrong.
Volume Pulse Gold
Volume divergence against trend, ranked — where participation is quietly leaving or arriving ahead of price.
Insider Buying Gold
SEC Form 4 filings parsed as they land — open-market purchases by officers and directors, ranked and filtered.
Paper Trading Gold
Log shares and options from any surface, track open positions and close with real P&L — without risking capital.
Macro Compass Free
Growth, inflation, liquidity and rates on one board, so you know which regime you're actually trading in.
Fed Monitor & FOMC Free
Meeting-by-meeting rate path priced off the futures curve, with the corridor and every decision date marked.
Sector Heatmap Free
Rotation across every sector, anchored to any date back to 1993 — Lehman, the COVID low, the 2022 bear, or a date you pick.
S&P Seasonality Free
Decades of month-by-month and day-of-year behaviour, with the sample size shown so you know how much to trust it.
CMBS Monitor Free
Commercial mortgage stress by property type — the slow-moving credit story that shows up in banks before it shows up in equities.
Discord Community Diamond Plus
Live alerts pushed the moment an engine fires — plus a room for the money questions that have nothing to do with the tape.
Why the archive matters

Most platforms delete the tape every night. We keep all of it.

Print data has a shelf life on every feed we've ever used — twenty-four hours, then it's gone. And no provider on earth will sell you that history back after the fact.

So A1 Flow writes a second permanent copy of every print it sees. Which means the questions you can only answer with history — what did positioning look like the week before that move — get answerable here and nowhere else, and they get more answerable every day.

Inside the engines

What you're actually looking at.

Four of the boards people spend the most time on, explained the way we'd explain them to somebody opening their first account.

01

Re-Rating

Diamond

Sometimes a company earns exactly the same dollar it earned last year, and the market decides that dollar is worth three times more. Nothing about the business changed. The market changed its mind about what the company is.

Think about two students who both average a B-plus. One has a reputation for coasting, the other is known as the kid on the way up. Same grades. Completely different expectations. When the room changes its mind about who you are, everything that follows changes with it.

Stocks do that, and here's the part that matters: the market changes its mind slowly. It isn't one morning. It's a story that spreads over months as more people come around to it. So if you can tell when the mind-change started, you're standing near the front of a line that's still forming.

What the board shows you

Names where the market has started paying up, the month it started, what it used to pay versus what it pays now, and how much price has already moved since that date. In plain words on the card: re-rated around March, 15x to 58x, up 34% since. One glance tells you whether you're early or whether the party already happened.

Where most screeners get this wrong. If a company's earnings fall, the multiple goes up on its own — that's division, not a re-rating. We make the price do the work: earnings have to be holding steady or improving while the market pays more. Otherwise a bad quarter looks like a breakout.

02

Earnings Inflection

Diamond

There are people whose entire job is guessing what a company will earn next year. Two things are true about them: they move in herds, and they move slowly.

When one of them raises their number, the others don't jump the same day. They follow over weeks and months, one at a time, each one nudging the consensus a little higher. By the time the number everyone quotes has moved, the move has been underway for a while.

An inflection is the turn — the moment a name goes from estimates drifting down to estimates starting to climb. That first turn is the quietest part of the whole sequence, because almost everybody watches the current number instead of the direction it's traveling.

What the board shows you

Companies where the direction just changed, roughly when it changed, and how forceful the turn is. Not a prediction. A statement of fact about what the professionals just started doing — and they rarely do it once.

How people use it. As a watchlist, not a buy button. A turn gives you a reason to go read the company while it's still uncrowded, instead of meeting it three months later in a headline.

03

Undervalued

Diamond

A $4 stock is not cheap. A $600 stock is not expensive. The share price tells you one thing only: how the company chose to slice the pie.

Cheap is a completely different question. What do you get for your dollar? How much does the business actually earn. How much real cash lands in the bank. What does it own against what it owes. And how fast is any of that growing.

Those answers live in two documents almost no retail investor ever opens — the balance sheet and the cash flow statement. Not because they're secret. Because they're dense, unglamorous, and nobody ever taught you to read one.

What the board shows you

We read those statements across thousands of names every day and surface the companies that are cheap on what they own and what they earn — not cheap on the ticker. A quality company the market is currently mispricing, versus a broken one whose price is telling the truth. Those look identical on a stock chart and nothing alike on a cash flow statement.

Why cash flow gets the last word. Earnings can be dressed up. There's a lot of room in accounting. Cash actually arriving in the bank is much harder to fake, which is why it carries the most weight here.

04

Daily Conviction Board

Diamond

Any single signal can be wrong. A cheap stock might be cheap for a very good reason. Heavy call buying might be somebody hedging. A turn can turn back.

So here's the question this board asks instead: what happens when the valuation engine, the inflection engine, the re-rating engine and the live options tape all land on the same company on the same day — without any of them knowing what the others found?

That's convergence, and it isn't just a louder signal. It's a different kind of information. Four unrelated questions, four unrelated data sources, one answer. The engines can't be agreeing by coincidence, because they aren't looking at the same thing.

What the board shows you

Every name where that happened today, and which engines agreed. Two boards overlapping is worth a look. Four is rare, and it's the shortest list on the platform.

Why it saves you the most time. There are thousands of tickers and only so many hours. This is the page that tells you where to spend them — it's the one most people open first and the reason they stop opening twelve tabs.

Every board names what it measured and the window it measured over, so you can judge it instead of trusting it. None of them tell you what to buy — that part stays yours.

Compare

Why is this so much cheaper?

Because flow is one engine here, not the whole product. Platforms that sell flow alone have to charge flow-alone prices.

The community

Money is bigger than the tape.

Diamond Plus opens a private Discord where the engines post the moment they fire — and where the conversation covers everything a brokerage account sits inside of. Not signals. Not picks. The mechanics nobody sat you down and explained.

Retirement accounts
How a 401(k), Traditional IRA and Roth actually differ. Match, limits, rollovers, and the order most people are told to fill them in.
Credit
What actually moves a score, what doesn't, utilization, how long things stay on a report, and how to read your own.
Cash & HYSA
Where cash belongs, how high-yield savings, money market funds and T-bills compare, and why the rate you see moves with the Fed.
Taxes
How investment income is taxed, short versus long term, wash sales, and what a brokerage 1099 is telling you.
Marriage & money
Combining finances or keeping them separate, what changes at filing time, and the conversations worth having before and after the wedding.
Market stats
The numbers behind the narrative — breadth, positioning, seasonality and what the data has actually done historically.

Brand new to this? Good. There are small-account challenges that walk through the mechanics from zero — how position sizing works, what diversification is doing for you, how to build a watchlist and how to size risk when the account is small. Structured lessons with real numbers, worked step by step. You bring the decisions; the room explains the machinery behind them.

Built to teach

Tired of apps that work against you?

Most trading apps are built to take your money, not to help you make it. They push signals that lose more than they win, parade the winners and bury the losers, and dress up a coin flip as an edge. Ask why a trade was suggested and you'll never get an answer.

A1 Flow doesn't send signals. It shows you what the data says and names the method it used to say it. Every board names what it measured and the window it measured over, because a number you can't interrogate isn't intelligence — it's a guess with a font.

Every surface carries an explainer for the concept underneath it: what open interest actually measures, why dealer gamma pins price, what a dark pool print does and doesn't tell you. No finance degree assumed.

We don't tell you what to trade. We give you the tools to decide for yourself.
