Follow the structure — the day call and the morning note, wherever you are
A TRADING DAY WITH HELIOS

What you get at 08:30, at 10:30, and every hour after.

The day is a sequence of reads, each with a time stamp and a record. You never have to guess what the structure says right now.

08:30 · The structure

  • Where dealers are long or short gamma
  • The zero-gamma line, the walls, the magnet
  • The regime, and what it has meant for the next hour on our own tape
  • The premarket read, before the open

10:30 · The day call

  • One call per symbol, bullish or bearish, from the session's own prices
  • Strong calls: right 92% of the time
  • Graded against the close, printed the same evening
  • NO CALL when the morning gave nothing, and that is shown too

During the session · The hour read and the Day Map

  • BUY CALLS or BUY PUTS for the next 60 minutes, with the reason: positive gamma, the line, the day call
  • The map: the line, the magnet, the walls, the distance to each in basis points
  • Every flip, wall touch, magnet reach and reversal, time-stamped as it prints
  • A Telegram alert the minute the read changes
UNDER THE HOOD

Built around how dealers actually hedge.

The same market-structure machinery a gamma desk runs, dealer positioning, hedging pressure, liquidity, read live and explained in plain words. Nothing black-boxed.

Dealer gamma and structure

  • Net gamma, calls and puts by strike, from our own option chain every two minutes
  • The zero-gamma line, 0DTE and all expiries
  • Gamma walls with strength, the magnet level
  • Distance to the line and to the walls, in basis points

Regimes and the line

  • Positive gamma: dealers lean against moves, the trend of the day holds
  • Negative gamma: dealers lean with them, walls break and moves run
  • Regime flips as they happen, with the level that caused them
  • Which side of the line the tape holds, and what that has meant for the next hour

Flow and order-book timing

  • Options flow by expiry and strike
  • Order-book imbalance and the top of book
  • Block prints over $250k notional, live
  • Reads that only fire when flow and structure agree

Volatility mechanics

  • Vanna and charm pressure through the day
  • Term structure and the implied-volatility surface
  • Expiry-aware behavior on 0DTE and expiration days
  • Pin risk into the close

The paper book

  • The morning call traded on a paper account, fixed rules
  • Every entry and exit broker-timestamped
  • Shown to members live, on the ledger
  • Stops and flattens published, never edited

Grading, in public

  • Every read graded on our own tape, forward, never backfilled
  • Records rebuilt every evening and shown live
  • What fails is retired, and the retirement is published
  • No number ships without a record behind it
The signal, end to end

One read at a time, with a clock on it.

The now box tells you the call of the day, the read for the next hour and where the structure sits. When the hour has no read, it says WAIT and names the lean. Nothing to interpret.

When it changes: the map prints the event with its time: a line cross, a wall touch, the magnet reached, a reversal back through the open. The next read is named. You always know where the session stands, even if you looked away.

FREQUENTLY ASKED

What traders ask first.

If your question is not here, email contact@helios.markets.

What exactly does Helios predict?

One thing, precisely: at 10:30 ET Helios calls the session BULLISH or BEARISH and claims the close will land on that side of the 09:30 open. When the evidence is clear the call is marked strong; when there is not enough of it there is no call and the screen says so. On our own tape that call has been right 82% of 50 called sessions, 92% when strong. The hour read speaks only in one structure state, the one that has earned it on our tape, and the Day Map is structure, labelled as structure: levels, regime, distance, events. Directional accuracy is not options P&L; what you do with the direction is below.

What can I act on after the signal?

A direction and a horizon. The day call is a filter for the rest of the session: which side of the market to work and which side to leave alone until the close. The hour read adds a sixty-minute lean when the structure lines up, and says WAIT with the reason when it does not. The Day Map gives the levels that frame an entry and a target: the zero-gamma line, the walls, the magnet, and the distance to each, live. Alerts arrive on Telegram as any of these change. A right call on a quiet day can still lose premium to time and spread, which is why the read comes with its drift and strength, so you can tell a thin call from a decisive one.

What does Helios supply, and what do I choose?

Helios supplies the call with its drift and strength, the hour read with its reason, the Day Map levels and every event on them, Telegram alerts as the reads update, and a public record graded on our own minute bars every evening. You choose the instrument, the strike, the expiry, the size, the entry, the exit and the risk. Helios never sends an order and never tells you what to buy; it tells you which way the session leans and shows you the score.

What does a difficult session look like?

Two real sessions from the record, exactly as members saw them.

Friday, October 16. 10:30 ET: both symbols well below their opens. Both calls BEARISH, both strong. QQQ closed 216 bp under its open and SPY 129 bp under: both right, and the strong tag told you at 10:30 that the session had already chosen. The hour read spent most of the day on WAIT: negative gamma, no hour-scale rule.
Wednesday, October 21. 10:30 ET: SPY a little below its open, a BEARISH call, not strong. QQQ flat: no call. The tape turned in the afternoon and SPY closed 25 bp above its open. The call was wrong. It stayed on the screen all day, was stamped WRONG at the close, and counts against the 82%. A weak call on a flat day is what a miss usually looks like; the strong tag is there so you can size the two cases differently.

What is the hour read?

The direction for the next 60 minutes, spoken only when the structure is in the one state that has earned it on our tape, and silent otherwise. In that state the next hour has gone with the call 62% of the time and 70% at two hours. In every other state the box says WAIT and tells you why, so you never trade a coin. Which state speaks is not published.

What is the Day Map?

The session's structure, live: the regime, the line, the magnet and the walls with the distance to each, what each regime has meant for the next hour on our tape, and every event as it prints: a line cross, a wall touch, the magnet reached, a reversal back through the open.

How do you grade yourselves?

Every read is stamped when it is made and graded forward on our own price tape, never backfilled and never by the system that made it. The day call is graded against the close; the hour read against the price 60 and 120 minutes later. What fails is retired and the retirement is published. The ledger is public, and the research page keeps the protocol and the retired reads.

What data do you use?

OPRA options chains with open interest for both symbols, SIP minute bars, dealer positioning models calibrated against open interest and observed hedging behavior, real-time price and volume, and order-book data for imbalance. Volatility surfaces are smoothed with a no-arbitrage model.

How are the tiers gated?

Each payload is filtered on the server before delivery. Free sees every call after the close, graded, with the record. Day Trader has the call live at 10:30 with its drift and strength, the hour read, the Day Map, the live structure and Telegram alerts. Pro adds the per-strike gamma, the positioning ladders, the volatility surface and API access. Your key encodes your tier.

Do you execute trades?

Not yet. Helios is signals today. Member trading on your own brokerage account, from the same screen, is built and in testing and opens when the broker agreement is signed. The paper book you see is a simulated account that trades the morning call under fixed, published rules. There is no managed capital and no individualized investment advice.

What symbols do you cover?

SPY and QQQ, the two most liquid index options in the world, both live. Pro customers can request additional liquid US equity options coverage per desk.

Is there a trial?

No. The public record is the trial: every call since August, graded, wins and losses alike. Day Trader bills monthly and cancels any time. Desks evaluating Pro can contact us.

How do I cancel?

Self-serve from your account. Subscriptions bill monthly and cancel at the end of the current period.
