Candella vs Interactive Brokers for deploying an algo
Interactive Brokers gives you direct execution across nearly every asset class, and if that is what you need, it is hard to beat. But getting an algo live on it means building against the IBKR API and keeping a gateway running and authenticated. Candella takes a different job: you send one signed request per trade and it executes across connected brokerage accounts, including your followers', with no infrastructure to run.
Side by side
| Candella | Interactive Brokers | |
|---|---|---|
| Setup to go live | Generate API keys and send one signed HTTP POST per trade. A Python SDK wraps it to one line. | Build against the TWS API or Client Portal API and keep IB Gateway or Trader Workstation running and authenticated. |
| Infrastructure you run | None. Candella hosts the endpoint and the execution. | You run and maintain the gateway and session, including re-authentication and API pacing limits. |
| What a signal does | Your algo's decision copies into connected brokerage accounts with manual approval and risk caps. | Your code places the order directly in your own Interactive Brokers account. |
| Distributing to other people | Built in. Fan out to your followers' own brokerage accounts, non-custodial, each with their approval and caps. | Not a self-serve feature. Trading other accounts requires an Interactive Brokers advisor setup. |
| Brokers reached | Webull, tastytrade, E*Trade, Moomoo, and Public through SnapTrade. | Interactive Brokers accounts. |
| Asset coverage | Equities and options today, with crypto on the way. | Broad: stocks, options, futures, forex, bonds, and more. |
| Custody | Non-custodial. Each account keeps its own broker connection; Candella never holds funds. | Your funds are held in your own Interactive Brokers account. |
The difference: no gateway to run, and distribution built in
The hard part of putting an algo into real accounts is rarely the strategy. It is the execution layer: a gateway that has to stay logged in, session and pacing limits, and per-account plumbing. With Candella there is nothing to run. You send the decision, and it becomes real orders across connected accounts, with approval and caps. And because it fans out to your followers' own brokers, one algo can trade many accounts without you touching a single one.
Interactive Brokers alternative, questions
What is the easiest alternative to the Interactive Brokers API for automating trades?
Candella lets you skip building and running the Interactive Brokers API and gateway. You send one signed HTTP POST per trade and Candella executes it across connected brokerage accounts, with manual approval and risk caps. It is built for getting an algo's trades into real accounts without an execution stack of your own.
Do I still need to run IB Gateway or Trader Workstation with Candella?
No. Candella is a hosted, signed HTTP endpoint. There is no gateway to run, no session to keep alive, and no daily re-authentication.
Can Candella copy my algo into other people's accounts?
Yes, that is the core use case. Your signal fans out to your followers' own brokerage accounts, non-custodial, each with manual approval by default and the caps they set. Distributing to other accounts on Interactive Brokers requires an advisor setup.
Is Candella a replacement for Interactive Brokers?
No. Interactive Brokers is a broker; Candella is software that turns your algo's signals into real orders across connected brokerage accounts. If your goal is to distribute a strategy to real accounts without building on a brokerage API, Candella is the faster path. If you need direct execution in your own account across many asset classes, that is what a broker like Interactive Brokers is for.
