What It Is

GammaLedger is a local-first options trading journal and portfolio analytics tool focused on tracking complex options strategies, dashboards, P&L, win rate, risk metrics, and strategy attribution. It is important to note that the captured text does not indicate that it is a cryptocurrency exchange, wallet, or DeFi platform. Its terms also explicitly state that it is not a broker, exchange, custodian, investment adviser, or financial institution, and that it does not execute trades, route orders, or manage accounts.

Core Evaluation Dimensions

In terms of asset support, the site highlights PMCC, Wheel, Iron Condor, multi-leg strategies, and Greeks monitoring, placing it firmly in the options analytics category. It does not disclose any supported cryptocurrencies, on-chain assets, or trading pairs. As for fees, the project is labeled as AGPLv3 open-source and free, though commercial, proprietary, institutional, or hosted use may require a separate commercial license. Since it does not match or execute trades, there is no trading fee information. KYC is not mentioned; given its nature as a local tool, the text does not show any registration review or identity verification requirements.

Security, Compliance, and Funding Capabilities

GammaLedger’s biggest selling point is privacy: it uses a local-first architecture, stores data in the browser’s IndexedDB, claims to have no cloud storage, and says trading data does not leave the device. Optional API keys may be stored locally and encrypted when browser encryption is available. However, this should not be mistaken for financial-grade custody security. Users are still responsible for device security, backups, browser permissions, and protecting exported files. The platform does not provide cold wallets, insurance, asset custody, fiat deposits or withdrawals, and it does not disclose any regulatory licenses.

Pros, Cons, and Who It Is For

Its strengths are that it is open-source and free, privacy-friendly, and focused on professional options trade review. It is suitable for active options traders, portfolio managers, and quantitative analysts. Its limitations are equally clear: it is not an entry point for crypto trading, cannot buy or sell coins, cannot custody assets, and cannot connect to brokerage accounts to place orders. AI outputs may be inaccurate, and the use of third-party AI/API services may result in data being transmitted to external services.

Access from China and Alternatives

The captured text does not provide information on accessibility from mainland China, ICP filing status, payment channels, or localization support, so its accessibility in China can only be rated as unknown. If users need crypto asset trading or on-chain operations, they should choose an exchange, non-custodial wallet, or DeFi tool with the relevant capabilities. If the need is options trade review, GammaLedger is better suited as a localized analytics and journaling tool rather than a trading platform.
