DG3 · Prediction Market Terminal

Spot the Edge.
Beat the Odds.

Real-time edge detection and sub-100ms execution across prediction markets. Built for active traders. Phase 0 is live on Polymarket.

DG3 is an intelligence layer on top of Polymarket. It watches every market, surfaces markets with edge, sizes your positions using Kelly fractions, and routes your orders fast. You don't browse. You act on signal.

From signal to position

Here is the path every trade takes through DG3. It plays automatically, or click any step.

Core Concepts

Key terms used across DG3. Read this once and the rest of the terminal makes immediate sense.

STREAM
A live feed of markets by domain. DG3 currently covers Sports and Esports. Your Deck is built from the streams you subscribe to.
DECK
Your trading cockpit. One card per subscribed stream, each showing the highest-volume active market in that stream. Up to five workspace tabs (alpha).
MARKET
A single tradeable prediction with a YES side and a NO side. Prices are the implied probability.
EV
Edge in cents. DG3's measure of how mispriced a market is. A +6c EV means fair value is 6 cents above the current ask - the price is in your favour by that amount.
KELLY SIZING
A method that sizes your trade based on your balance and the market's implied edge. Bigger edge means bigger position. Options: 1/4, 1/2, 1x, or Custom.
1-CLICK TRADE
A mode that pre-fills your Kelly size and execution style so every trade goes straight to review - no re-entering settings each time. Works best with an Embedded Wallet.
SPREAD
The gap between the best ask and best bid. Tighter means lower friction.
EXPOSURE
Total capital at risk across open positions, tracked live by market category.

What is DG3
Getting Started · Onboarding

Onboarding

Three steps to a live deck. No separate account needed. DG3 connects through your wallet or social login.

dg3.trade · Onboarding

Onboarding. Sign in with Google, X, Discord, or a wallet
01
Sign in
Use Google, X, or a wallet. Social logins create an embedded wallet automatically. If you sign in with an external wallet, you'll confirm which address to trade from in the next step.
02
Set a handle
Optional. DG3 generates one if you skip. Change it anytime from Settings.
03
Pick your streams
Choose 1 to 5 market domains. This builds your Deck. Add or remove streams anytime from My Streams.

Embedded vs External wallet

After picking streams you choose which wallet executes trades.

Recommended
Embedded Wallet
1-Click tradesNon-custodialGasless
No wallet popup per trade. Required for sub-100ms execution and 1-Click Trade. Keys secured by Privy, DG3 never holds them.
External Wallet (EOA)
1-Click unavailable
Wallet prompt required on every trade. Slower execution. Switch to Embedded anytime from Settings.
Once done

Your deck loads immediately with your streams active. You're ready to trade.

The Terminal · Streams

Streams

Live market feeds by domain. Your deck is built from the streams you follow.

Managing streams

Open My Streams from the top nav. Add, remove, or reorder subscriptions. Changes apply to The Deck immediately. You can hold up to 5 streams on your deck at once.

Stream structure

Each stream covers a specific domain. DG3 currently offers Sports (Cricket, Football, Basketball, and more) and Esports (CS2, League of Legends, Dota 2, Valorant, and more). Subscribe to one or more from My Streams.

Sort options

  • Volume, highest total volume first (default)
  • Liquidity, deepest order books first
  • Ending soon, closest to resolution first
  • New markets, most recently listed first
  • Trending 24h, biggest volume movement in the last 24h
Removing a stream

Open positions in that stream are unaffected. They stay in your portfolio until they resolve or you close them.

The Terminal · Edge Finder

Edge Finder

Search an event to load its markets ranked by EV. Search a league to browse its full event tree. When the terminal is already open, league and team results only fill the search bar for drill-down - select an event or press Enter to navigate. This is where you find edge, not just markets.

How to use it

01

Type an event name to load its markets ranked by EV. Type a league name to open a tree of its events. When a deck is already open, league and team results only fill the bar for drill-down - refine to an event and press Enter to load it.
02
Browse the market list
Markets are grouped by type: Game Lines, Spreads, Totals, and so on. Each row shows outcome prices, volume, liquidity, spread, and an EV badge when data is available.
03
Open a market
Click a market row to load its analysis in the Intelligence Pane. Click an outcome chip to open the Trade Desk with that outcome pre-selected.

Context banner

The banner across the top shows the event name, kickoff time, live score if in play, and a Rules pill for resolution criteria. In league mode it shows total market count across all events.

Flat mode

Toggle flat mode in the toolbar to collapse the market type groups and see all markets in a single EV-ranked list.

EV badges

A badge only appears when DG3 has edge data for that market. No badge means no data, not zero edge.

Trading · Kelly Sizing

Kelly Sizing

DG3 sizes your trades based on your balance and the market's edge, not a flat dollar amount.

Most traders size by feel or a fixed percentage. Kelly does something smarter: it scales your stake to how large the edge is. DG3 reads the edge as an EV in cents, then sizes against your balance and your chosen fraction. Try it below.

If you win+$969
If you lose-$1,050

How EV maps to probability

EV in cents is just the gap between a market's price and where DG3 reads its true value. A market trading at 52¢ with an EV of +6¢ implies a fair value near 58¢, a 58% chance. The wider that gap, the larger the slice of your balance Kelly puts to work. You never type a probability yourself, DG3 derives the edge and sizes the trade for you.

Choosing a fraction

Full Kelly (1x) is the theoretical maximum, but it produces large swings in practice. Edge estimates are never perfect, and overestimating at full Kelly is expensive. Most active traders run at 1/2 Kelly as a deliberate buffer.

1/4 Kelly
Conservative. Low variance. A good starting point if you are new to prediction markets.
1/2 Kelly
Recommended. Most of the long-run return with half the variance of full Kelly.
1x Kelly
Maximum expected growth, maximum variance. Use only with strong confidence in your edge estimates.
Custom
Any multiplier between 0.05x and 1x.
Sizing recalculates per trade

Your position size uses your live balance at the moment of each trade. As your bankroll grows or shrinks, sizes adjust automatically.

Trading · 1-Click Trade

1-Click Trade

Pre-fills your Kelly size and routes your order automatically. You review and place in one tap.

Works best with Embedded Wallet

With an Embedded Wallet, 1-Click opens the trade modal instantly - no wallet signature popup per trade. External wallet users will see a signature prompt on each order. You can switch to Embedded anytime in Settings.

Setting it up

Click Set Up in the 1-Click strip at the top of your deck. A panel slides in with two settings:

  • Kelly fraction, which fraction pre-fills your size per trade. See Kelly Sizing.
  • Execution style, how your order is routed (Market or Limit). See Execution Styles.

Once you pick a fraction and execution style, hit Save & Enable. The strip turns active and a 1-CLICK ON pill appears in the nav bar.

The 1-CLICK TRADE toggle is also visible inside the Trade Desk itself. Tap it to switch 1-Click on or off at any point without leaving the panel.

Pausing

Toggle the 1-Click strip to pause or resume anytime. Your settings are kept. Click the 1-CLICK ON pill in the nav bar to view or change config from anywhere in the terminal.
