The positions we actually open

  • Not just resold data: each one is a position we actually opened on our own strategy, shared with members after entry.
  • Each one shows the fill, the side and a score, then we track the price and the best and worst return until it settles at expiry.
  • Nothing cherry-picked: every position counts in the performance page, and new positions are pushed to your phone.

Short alert

In a bull market, when should you start to be careful?

The hardest part of a rising market is not buying, it is knowing when to tighten up. Our short alert is built on DarkFill's proprietary indicators and strategies. Backtested from 2010 to 2026: after an alert, the market is clearly more likely to pull back over the following weeks.

On the member page this shows up as a 1–100 short score; at 62 or higher a red arrow marks the candle and an alert goes to your phone.

SPY daily candles with market risk alerts marked
SPY daily candles. Red triangles mark short alerts (score 62 or higher), every one of them in each period (only the first within 5 trading days counts). Alerts often came near short-term highs and were followed by several 6%–15% pullbacks. Others were followed only by choppy trading or even more gains; the latest-year chart shows the hits and the misses. Treat an alert as a cue to cut risk, not a sell signal.

Volatility forecast · for day traders

Know which hours will move and which to sit out, before the bell

Day traders lose money two ways: no position when the market moves, and getting chopped up when it doesn't. Here are five checkpoints from the prior close into the close, each telling you whether a big move is likely next. All five are graded high reliability: found on one part of the data, checked on another, and updated on the member page every day.

  1. After the close

    Tomorrow's range

    On days flagged for a wide range tomorrow, the next day moved 1.5% or more 88% of the time, versus 26% on all days.

  2. After the close

    Pullback risk

    When the risk reading is high, SPY fell 2% or more within 10 days 60% of the time, versus 37% overall and 29% when the reading is low.

  3. Morning

    Today's volatility outlook

    Shortly after the open, the day gets a grade. Out of sample, days graded low reached a 1.5%+ range only 2% of the time, versus 21% for days graded high.

  4. Midday

    Afternoon outlook

    At midday, the afternoon gets a grade: afternoons graded calm moved about 0.35%, versus about 0.7%–0.8% for those graded active.

  5. Into the close

    Late-day risk

    When the late-day alert is on, the market made a big move before the close 57% of the time. On days with no alert at all (61% of days) it happened only 3% of the time.

In SPX pointsOn the member page the expected range is written in SPX points, no maths needed.
Today's eventsEconomic data, Fed days and big earnings sit on the same page as the forecast, so you see them together before the open.

All figures are historical frequencies, not guarantees, and none of them predicts direction. Members see the live reading for each one on the site every day.

About DarkFill

Most big money moves where you are not looking

The name comes from dark fills: positions built quietly before a move, the calm before the storm, the undercurrent of intent moving beneath a noisy, crowded market. Any website can show you a price chart. DarkFill is not here to give you what everyone already sees, but to light up what most people never see.

We sort those trades by fill side, price level and time, add a backtested short alert and volatility forecast, and hand it all to you each day as DarkFill signals, with the important ones pushed straight to your phone.

Light up the dark.
See the unseen.

Not another copy of what everyone already sees, but the part most people miss.

FAQ

Frequently asked questions

What is Darkfilled? Are these your own positions?

Yes. Darkfilled is the option positions we actually open on our own trading strategy, shared with members after entry: the fill, the side and a score, then tracked all the way to expiry. The strategy's exact rules are not public. Every position counts toward the track record, good or bad.

What do the scores mean?

The Darkfilled score runs 0–100: the higher it is, the more likely the position produces a large gain. The short-alert score is a 1–100 risk reading: the higher it is, the more likely a pullback over the following weeks. A higher sector sentiment score means the money move deserves more attention. Scores are statistical tendencies, not guarantees.

Are DarkFill signals investment advice?

No. DarkFill signals are data-based statistics and opinions for reference only, not a recommendation to buy or sell any security. We are not a broker-dealer or a registered investment adviser. Trading involves substantial risk; past results and backtests do not guarantee future results.

Which pages do members get?

The seven DarkFill signals pages: Darkfilled (our actual positions), performance, the volatility forecast, the short alert, events (today's events and market news), sector sentiment and Uncle Phil's notes.

Where does the data come from?

Built on DarkFill's proprietary indicators and strategies; raw market data comes from market data providers, plus the public economic calendar. Some sources are delayed by nature; pages note this where it applies.

How often is it updated?

During market hours DarkFill signals refresh automatically: new Darkfilled positions are pushed to your phone right away, and sector sentiment usually shows new data within a minute or two; the volatility forecast comes out before the open and is updated in the morning and into the close; performance settles automatically as positions expire.

How do I cancel?

Sign in, open your account page and click “Manage billing / cancel”, then cancel in the Stripe billing page. You will not be charged again, and you keep access until the end of the period you paid for.

Can I get a refund?

Your first successful $99 payment can be refunded in full within 7 days. The $1.99 trial fee is non-refundable. Later payments are generally non-refundable, but duplicate, erroneous or unauthorized charges are refunded. See the Refund Policy; email [email protected] to request one.

Does it work on my phone?

Yes. It works in desktop and phone browsers. Add it to your home screen to receive push alerts (on iPhone, add it from Safari and open it from the home screen icon).
