Users can investigate holders, large fills and wallet histories inside the terminal rather than separating research from the trading workspace.

The Polymarket product is listed for Windows and macOS. Traderline also has a separate Betfair product with desktop and iOS support; that mobile availability should not be applied to Polymarket. The documented Polymarket connection imports a signer private key into the local application. This provides signing capability and is substantially more access than looking up a public wallet in a read-only research tool. Review the exact supported account and wallet-creation flow before setup. ### Who it is for - Desktop traders who prefer price-ladder execution. - Researchers studying wallets behind large fills. - Betfair users comparing a familiar workspace with Polymarket. ## Features and coverage - **Desktop ladder** Use the Polymarket terminal on Windows or macOS to work price levels in a trading-oriented interface. - **Holder tables and filters** Inspect side, position size, entry and PnL, and filter for profitable wallets or newly created accounts. - **Large-trade tape** Filter the live trade feed, including trades above $1,000, and open the wallet behind a fill. - **Wallet profiles** Review open and closed positions, profitability, history and best wins. - **Persistent research labels** Assign labels such as experienced, bot or recreational and retain them for later research. These are organizational tags, not verified identities. - **Separate Betfair product** The Betfair route supports desktop and iOS, distinct from Polymarket’s desktop availability. ## Workflows with Traderline ### Investigate a fill Open a large trade in Sonar and inspect the wallet’s positions and history before interpreting its significance. ### Label a research set Use consistent custom labels and refer to them when the same wallets reappear, without treating a label as verified identity. ### Prepare a desktop session Configure the supported local signer connection and confirm market, outcome side and size in the ladder. ## Pricing and total cost The official site advertises both venue products as free without a subscription. Exchange charges and the account’s own trading costs remain separate. ## Getting started **Before you start:** Betfair iOS support does not establish Polymarket iOS support. 1. Download the correct desktop version from Traderline. 2. Open the Polymarket setup guide and check the supported account/wallet creation flow. 3. Follow the local signer instructions, noting the private-key import requirement. 4. Open a market, inspect the ladder and use Sonar before configuring a trade. Polymarket setup imports a signer private key into the local application; the trading connection is not read-only.

A closer look ## Ratings & reviews Editorial rating **3.5**/ 5 0 user reviews PredictionToolkit editorial ### Our take on Traderline Ladder execution and integrated holder research form a focused desktop workflow. The signer-key import is a material distinction from public wallet lookup, while free access and Betfair’s mobile product should not obscure venue charges or Polymarket’s platform scope. Based on documented features, setup and access terms.
