👉 Want real-time whale signals?
On SightWhale, we provide:
A signal system is the whole pipeline: pull Polymarket data, turn it into features, run rules or models, fire alerts, and optionally hand off to execution—while you can actually observe what broke and cap how bad a bad day gets.
The good ones are deliberately boring:
Whale flow and Smart Money scores slot in naturally as inputs—usually as filters or score boosts on top of price, liquidity, and anything tied to how the contract resolves.
Evaluation discipline belongs in your backtesting habit—signals you never measure are just opinions with notifications.
A practical build order:
Define the job
Examples: “surface mispricing vs my model,” “flag Smart Money accumulation,” “warn on resolution risk changes.” One primary objective per v1.
Choose the observation clock
Event-time vs wall-clock; batch vs stream. Polymarket short-term signals usually need near-real-time ingestion.
Build feature primitives
Normalized order-book imbalance, rolling volume z-scores, cross-market spreads, whale net flow windows—each with explicit lookback and timezone.
Encode decision logic as code
Start with transparent rules before opaque ML. Rules are easier to audit when something breaks live.
Add a scoring layer
Map features to priority (0–100) and confidence buckets; separate “interesting” from “trade now.”
Design delivery
Channels (app, email, webhook), throttling, deduplication, and context blocks (market link, rule name, key metrics).
Instrument everything
Log signal fires, user actions (if applicable), and post-hoc outcomes for closed markets.
Close the loop
Weekly review: false positives, missed positives, regime changes—iterate one knob at a time.
Illustrative v1 spec (not a product promise):
Ship a thin slice, measure honestly, then let complexity earn its keep.
| Layer | System role |
|---|---|
| Data store | Durable history for replay and audits |
| Stream / cron jobs | Reliable ingestion |
| Whale + Smart Money services | High-signal flow compression |
| Dashboards | Monitor latency and alert volume |
SightWhale provides real-time whale tracking, Smart Money scoring, and production-grade alerts—either as your entire flow layer or as a module inside a larger custom stack.
Illustrative fields—use SightWhale for live values.
| Field | Example (illustrative) |
|---|---|
| Example whale position | Signal-sized accumulation in one liquid market (hypothetical) |
| Win rate (resolved sample) | 60% over last N resolved trades (hypothetical) |
| ROI (time-windowed) | +11% over 90d on tracked activity (hypothetical) |
Live Polymarket whale positioning and Smart Money tiers: SightWhale.
Do I need code to build a signal system?
Eventually yes for repeatability; early versions can be spreadsheets if definitions are strict.
Should my first signal be whale-based?
Often combine flow with liquidity and resolution checks—Whale alone is noisy.
How many alerts per day is healthy?
Whatever your attention and review capacity can truthfully process—quality beats volume.
Can I automate trading immediately?
Not recommended until risk modules and paper phases prove stable.
Where does Smart Money plug in?
Usually as a gate or score boost, not the only trigger.
