Arch Public

Arch Public is an automated trading software platform that helps investors manage crypto, stocks, and ETFs through the exchange or brokerage accounts they already use. Designed as a trader’s operating system, it provides strategies intended to automate approaches such as accumulation, dollar-cost averaging, and capturing gains across market cycles. Users can connect accounts, select available strategies, and monitor activity, with tools for managing supported assets including Bitcoin, Ethereum, Apple, Tesla, Nvidia, and funds tracking major indexes, gold, and silver. Supported assets and availability vary by brokerage.

Arch Public emphasizes a zero-custody model: assets remain in the user’s own account, and the company says it cannot withdraw, transfer, or hold funds. Connections use OAuth where available or read-only and trade-only API permissions. Trades are logged for visibility, and users can pause, adjust, or stop strategies. The platform also publishes case studies comparing hypothetical backtested performance with buy-and-hold and dollar-cost averaging. These results are not actual trading returns and may not account for fees, slippage, or market impact.
