Build your own index.

Alpaca — US equities

You set the rules

Agents execute within
limits you set.

Agents follow your configuration and can keep trading 24/7. Mix stocks and crypto in one basket, rebalance on your terms.

  • Deploy an agent tracking your own index: BTC, ETH, AAPL, NVDA
  • Rebalancing on your thresholds, not a preset schedule
  • Agents can't exceed their allocated pot of funds
  • Nothing trades until you activate it. Pause and resume anytime

Inspect everything

Agent behavior is
always visible.

Every order, state change, and rebalance is recorded and shown in your dashboard. You never have to dig through exchange logs to understand what your agent did.

  • Track every order from placement to fill
  • Review the full history of what happened and when, across all agents
  • See exactly how allocation changed after each rebalance
  • Know whether an agent is actively trading or just running

Secure by design

Your keys and funds,
out of our reach.

The whole system is designed around one hard assumption: that even our own infrastructure could be breached. So your keys stay encrypted, unreadable even to us, and no one can withdraw your funds, no matter what fails.

In-browser encryption

Keys are encrypted in your browser and stored double-encrypted. Neither our services nor our staff can read them. Only your own agents can decrypt them.

Per-user infrastructure isolation

Your agents run in their own isolated environment. A breach of one user's environment can't reach another's keys or runtime. The boundary is enforced by the infrastructure itself.

Non-custodial

Your exchange keys carry the minimum permissions to place orders. An exposed key still can't withdraw your funds.

Reliability

Built to recover,
not just to run.

Connections drop. Servers restart. The platform is built for that, not on the hope that it won't happen.

Order integrity

Journaling and multi-layer reconciliation keep your agents in sync with the exchange, even after unexpected interruptions.

Supervised and self-healing agents

A supervision framework detects issues and triggers automatic recovery. Agents detect and fix transient issues themselves — without human input.

Durable audit trail

Every order and state change is written to storage that survives failures, leaving a complete history of what your agents did.

* We compared a few of the most popular solutions in each category.

Prefractal provides software for execution and monitoring. You define the basket, the limits, and when agents activate. We do not provide investment advice, portfolio recommendations, or trading tips. Built for self-directed users who understand that trading involves risk.
