SENTINEL · Event watch
The desk computes the option chain and whale positions around the clock. A sentinel is you pointing at one specific event inside those calculations, and the system pinging you the moment it occurs. Not advice to buy. A message that the thing you were waiting for has just happened.
The option chain lives 24/7. The put wall moves at 3 a.m., a 50 BTC structure gets assembled in five minutes, the gamma flip crosses spot while you are at work. No human watches 2,000+ instruments on two exchanges continuously. A machine does.
We checked the market: no service sells alerts on these events. Not “pricier than the competition” — they don’t exist.
A whale assembled a position — the desk recognised what exactly was assembled and named it: butterfly, condor, risk reversal, straddle, calendar spread and five more families. Condition — asset, family, size from N.
Big players assemble structures in one package away from the order book — a block trade. The desk catches every block on Bybit and recognises what was assembled. A rare event — roughly once a day, which makes the ping worth more.
Not the index, a specific instrument: when mark_iv on BTC-25DEC26-80000-C crosses a threshold. Deribit and Bybit combined — 2,000+ instruments across BTC, ETH and SOL.
Not «price reached the wall», but the wall moved by more than $N. The difference matters: the first means you are already there, the second means the market has rebuilt itself.
Price left the market makers' breakeven zone — the one that held in 82% of 368 verified settlements.
The market regime changed: from damping to acceleration or back. Dealers start amplifying the move instead of muting it.
The metric is known to the market, but we compute it on our own archive.
The point of maximum pain moved by more than $N before expiry.
Puts were more expensive than calls — now they are cheaper, or the other way round. A change in what the market pays for.
More than N contracts added on a specific strike within a day — quiet accumulation.
Bybit shows every hour which way the retail crowd leans; Hyperliquid shows where the whales stand. Condition — the gap between them wider than your threshold.
Liquidation clusters from the Hyperliquid chain are given away by at least three services. Charging for that would be dishonest, so we do not sell a cluster watch — it is simply in the radar.
Price approaches a cluster of whale leverage on Hyperliquid.
The list above is a set of examples, not a menu. The desk computes the option chains of Deribit and Bybit, whale positions, funding, OI and basis across ~800 perps, the retail long/short split and block trades, so the condition can be anything — as long as we have the data for it. Want to watch the ratio between two strikes? How open interest shifts on one specific expiry? Two conditions firing at once? Tell us what you need — we’ll tell you straight whether we can compute it, and set it up.
Describe your condition →The plans have alerts too — eight of them free. But that is a fixed catalogue of standard events (BTC/ETH, plus SOL/HYPE for crowd-vs-whales), the same for everyone: 🆓 liquidation cluster · whale liquidation ≥$1M · whale structure without the numbers · max pain shift · extreme funding · flow across the HL border · the daily watch · altseason barometer — 💠 large whale move ≥$25M · quiet accumulation · DVOL jump · term-structure inversion · crowd vs whales — 🔬 MM breakeven range · gamma flip. They are switched on in the bot with /alerts.
Sentinel is the opposite: any condition of YOURS. A plan alert says «the gamma flip happened». Sentinel says «your level was broken», «your strike crossed its IV threshold», «your wallet moved». Different jobs — hence different products.
Anyone can send a Telegram message. You are not paying for the message, you are paying for what is written in it. To see that a whale assembled a 50 BTC butterfly, you have to recognise the structure inside the trade flow — not see the trade, but understand what it adds up to. To see that a wall has moved, you need yesterday's snapshot of the chain. We have one since 10 March, every day, and nobody can reconstruct it after the fact. And since August the desk also records Bybit: greeks and IV for BTC, ETH and SOL options every half hour, block trades, funding and OI across all ~800 perps, the retail long/short split every hour.
Price
Price for the first 20. After that — $89/mo. Whoever joins at $49 pays $49 for as long as the subscription runs, however long that is. The price rises for the next ones, not for you.
On annual payment — a discount on every service: 💠 Agent −10% ($80/mo) · 🔬 Analyst −30% ($62/mo). Monthly payment carries no discount — the founding price is below both anyway.
