SPX 0DTE options signals · Launching soon

Every signal he takes,
on your phone.

A quant runs a systematic 0DTE SPX options strategy and trades it himself. When the model publishes a signal, you get it on your phone — direction, exact strike, entry, and managed exit updates as it plays out. Delivered by app push and Discord, timestamped and journaled, wins and losses.

Cadence measured on the live signal-only stream, July 2026

Win = a trade that banked profit on the way up under our exit rules — not held to the close. Backtested on recorded market data, June–July 2026; fills modeled at mid. Past performance is not indicative of future results.

Some days produce no signal. That means the bar was not met — not that the system needed to manufacture a trade.

From the backtested record

One signal, replayed without hindsight.

Follow one recent SPX signal from the modeled entry through the exit. The curve shows what the option premium did. The markers show what the exit rules actually banked. The quantitative model reads dealer positioning, flow, and price levels before publishing a signal.

Data windowJul 14, 2026 · backtested

Recorded market data; this signal is drawn from the same backtested sample window published on the track record — chosen as a mid-pack winner, not the best one. Entry modeled at the quoted ask — the price a buyer actually pays; exit at mid. Markers represent our exit rules; the premium peak is shown for context and is not presented as the achieved result.

The product

The signal is the product.
Everything else supports it.

One selective feed for SPX 0DTE options. When the model has a trade, the alert gives you the direction, exact contract, entry, and managed exit plan. When it does not, it stays quiet.

The signal
Direction. Exact strike. Entry.

A complete SPX options signal delivered in one readable alert — without a chart room, live stream, or paragraph to decode.

Managed exits
Bank on the way up.

The service keeps publishing management updates after entry. Results are judged under those exit rules, not by pretending every trade was held to the close.

Live journal
Every signal stays on the record.

Each signal is timestamped as it is published. Wins and losses remain visible; later market movement does not rewrite the original alert.

Delivery
App push and Discord.

The same signal feed reaches both surfaces in real time. Use the app, Discord, or both.

Market context
Enough context. No secret recipe.

Morning context and relevant price levels explain the environment without exposing proprietary thresholds or model internals.

Weekly review
A concise review, included.

A weekly review of published signals and market context, recorded and available to members.

The app

Glance. Decide. Get back to work.

The app puts the exact contract, entry, and latest management update in one place. Push notifications bring the signal to you; Discord carries the same published feed.

The record

The record includes
the red rows.

Every signal is logged as it plays out. The public record shows a recent chronological sample, including wins, losses, and sessions when no signal met the bar.

Small wins are not rewritten using a later peak. Losses are not removed after the fact. Quiet days remain part of the record.

Backtested performance and the live publication journal are labeled separately. No live-capital track record is claimed.
