DG3

DG3 is a web terminal built specifically for trading sports prediction markets on Polymarket, run entirely in the browser rather than through a bot or extension. The operator describes it as an intelligence layer sitting above the exchange: it watches markets across sports streams, ranks them by expected value and lets a trader act on what it surfaces instead of scanning manually. The product is in an early phase the operator brands as alpha access, live on Polymarket only, with sports as the stated focus rather than politics or economics markets.

Inside the terminal a trader works across three panels: a Deck of ranked markets from the Edge Finder, an Intelligence pane showing order book depth, sharp money positioning and news for whichever market is open, and a Trade Desk for sizing and firing the order. Kelly sizing and stop-loss or take-profit settings can be preset so a single tap executes a trade that matches a rule set defined in advance.

A trader opens DG3 in the browser and launches the terminal from the site itself, no extension or Telegram bot involved. The documentation frames onboarding as three steps to get a personal deck live, after which the Edge Finder ranks markets and the Intelligence pane loads whichever one is selected.

Orders placed from the Trade Desk route to Polymarket, the only venue the operator names for this alpha phase; DG3 sits as the interface and signal layer on top of that order book rather than as a separate market. The account section of the documentation lists a deposit and withdraw flow, and the FAQ addresses embedded wallets directly, which points to funds sitting on the platform between trades rather than a wallet approving every fill individually. The operator does not use the FAQ to spell out what that means for asset custody beyond naming the topic, so a trader should confirm the mechanics before funding an account rather than assume a non-custodial setup.

• Edge Finder ranking

  Ranks markets by expected value across every sports stream so a trader opens the highest-EV setup first instead of scanning each market by hand.

• Kelly sizing presets

  Pre-configures position size as a Kelly fraction so a single tap sizes a trade to the edge rather than a flat, guessed bet.

• One-click trade execution

  Fires a preset stop-loss, take-profit and size in one tap once armed, cutting the steps between spotting a setup and holding the position.

• Sharp money and whale tracking

  Surfaces order book depth, sharp-money line moves and wallet-level whale activity together in the Intelligence pane for whichever market is open.

• Volume-based rebates

  Credits rebates back to traders based on volume routed through the terminal, positioned by the operator as compounding the more a trader trades.

High-frequency sports bettors

Benefits most from sub-second execution and preset playbooks when a line moves fast and speed matters more than extra manual research.

Traders drowning in meta-work

Automates the scanning, cross-referencing and price checking the operator says used to cost twenty to thirty minutes before every single trade.

Kelly-discipline position sizers

Wants position size tied to a Kelly fraction and preset exits rather than eyeballing bet size after spotting an edge.

New sports-market entrants

Gets a ranked deck and Edge Finder that surface where the edge sits without having to build a personal scanning workflow first.

Traders wary of unproven platforms

Should weigh that the terminal is still labeled alpha access and has 140 of history, short of a full market cycle.

DG3 publishes no fee schedule on its homepage, in its documentation or in its own about page. Its FAQ lists separate entries on how much DG3 costs and on whether it charges trading fees, and a trader should open both before funding an account rather than assume a rate from the marketing copy. Alongside that, the operator promotes a Rebates program that pays volume-based credits back to traders who route flow through the terminal, advertised as a benefit without the credit rate spelled out. Polymarket's own per-market trading fee applies the same way regardless of which builder carries the order, so it says nothing about what makes routing through DG3 specifically cheap or expensive, and any rebate is a discount layered on top of that fee, not a substitute for it.

• Bundles market discovery, analysis and execution into one screen, cutting the meta-work a trader would otherwise do across separate tabs and tools.
• Presets Kelly sizing and stop-loss or take-profit levels so a high-conviction setup can be armed and fired in a single tap.
• Surfaces order book depth, sharp-money line movement and wallet-level whale activity in one pane instead of requiring separate lookups.
• Runs entirely in the browser, so there is nothing to install or configure before a trader can start using the deck.
• Pays volume-based rebates back to traders who route flow through the terminal, adding a return on top of whatever a trade already earns.

• Publishes no fee schedule anywhere in its own materials, leaving a trader to dig through FAQ entries rather than see a rate up front.
• Covers Polymarket only and sports markets specifically in its current phase, so it is not a fit for politics or economics traders.
• Has been live for a comparatively short stretch, per 140, meaning it has not yet been tested across a full market cycle.
• Runs on account funding and an embedded wallet rather than per-order external signing, which concentrates operational risk on however that account is secured.
• Describes itself as alpha access, a stage the operator's own language associates with features and behavior still being finalized.

DG3's account section documents a deposit and withdraw flow, and its FAQ names embedded wallets as a topic, which together point to funds sitting inside the platform between trades rather than an external wallet approving each order individually; the operator does not spell out custody terms beyond raising that question, so a trader should read that FAQ entry closely before funding an account. On transparency, the site names no fee rate and no security audit, and it currently badges itself as alpha access, language that signals a product still being hardened rather than one with a settled operational history.

DG3 reads as a genuine attempt to compress the scanning, analysis and execution steps a sports trader on Polymarket would otherwise do by hand into one browser terminal, and the Edge Finder and Intelligence pane are specific enough to judge rather than vague promises. What is missing is any stated price and a track record long enough to say how the execution and sizing tools hold up once volume and volatility both spike at once. A trader who already lives in sports markets and wants Kelly sizing and one-click execution has reason to try it carefully; a trader who wants a published fee, a multi-cycle history or coverage beyond sports should wait or look elsewhere.
