How to Connect an eToro Account to Acubic

Key takeaways

• Connecting eToro to Acubic takes five steps after you have a saved strategy: open the broker connection, log in on eToro's own page, set the capital figure, choose a rebalance frequency, and approve the first rebalance.
• The login uses eToro's OAuth flow, so your eToro password is entered only on eToro's page and Acubic receives a scoped, revocable token.
• On a standard eToro main account you choose Manual, a checklist of trades with nothing sent, or One-Click Approval, where nothing reaches eToro until you approve.
• Capital figure, frequency and mode can all be changed later without reconnecting.
• Disconnecting, or revoking access from eToro, stops further proposals and leaves every position where it is.

The question people are asking when they search "connect eToro to Acubic" is procedural: they already know what they want and they need the steps. This article is that walkthrough, in order, with enough context to understand each step without having to read five other pages. If you want to understand what the connection does once it is established, what it can see, and how the approval step works, how Acubic works with eToro covers that separately.

Before you start: build a strategy first

Two things must be in place before you can connect. You need an eToro account, and you need a saved strategy in Acubic. The strategy is the less obvious requirement.

Acubic binds a broker connection to a specific strategy. The connection is not a general account link: it attaches to a saved strategy, and that strategy has to exist before there is anything to connect to. One connection is enforced per strategy, so two strategies cannot both manage the same eToro account simultaneously.

The strategy creation step runs entirely without a broker. Acubic walks you through a short set of questions about your goals, risk tolerance, and the asset categories you want to include. The engine constructs a target portfolio from your answers and shows you the proposed holdings with their weights. Review it. Nothing touches eToro at this stage. You can use the strategy builder as a standalone analysis tool and connect a broker only when you are ready.

If you want the full picture of what happens between describing your goals and having live positions at your broker, how Acubic works is the complete guide.

Step one: open the broker connection flow

From a saved strategy, navigate to the broker connection section and select eToro. Acubic is listed in the eToro App Store as an approved third-party integration and connects through eToro's official API. No action on the eToro side is required before this step.

Step two: authenticate via eToro

Selecting eToro starts the OAuth flow. Acubic hands you off to eToro's own authentication page. You log in with your eToro credentials there. Your eToro password is never entered on an Acubic screen: the authentication happens on eToro's page, and eToro issues Acubic a scoped access token. Once you complete the login and approve the access, eToro returns you to Acubic with the connection established.

The access token is stored encrypted at rest and is never returned to the browser. It can be revoked at any time from inside your eToro account, independently of anything you do in Acubic. The ultimate off switch is not one this application controls.

eToro's own developer documentation describes the same model from the platform's side. In its SSO (OAuth) guide, eToro says that with this flow "the user authenticates with eToro rather than with you" and that "your application never handles their eToro password". A scoped token is a credential limited to the specific permissions (scopes) you approved on the consent screen, rather than full access to your account.

the access your application receives is limited to the scopes the user consented to and revocable by them at any time

Step three: set the capital figure

After the authentication step, Acubic asks how much of your eToro account it manages. This number defines the managed set: the boundary within which Acubic will read positions and propose trades. Positions outside this boundary are not touched.

Your eToro account does not need to be dedicated to Acubic. If you hold positions you want to keep independently, those stay where they are if they fall outside the capital figure. Holdings you have copied from other investors on eToro, and any Smart Portfolio allocations, are not included in the managed set regardless. You are assigning a portion of the account to Acubic, not handing over the entire balance.

The capital figure can be changed after connecting without disconnecting and reconnecting the account.

Step four: choose a rebalance frequency

Set how often Acubic checks whether your portfolio needs rebalancing: monthly, quarterly, or annually. Portfolios drift as holdings grow at different rates, and rebalancing brings the weights back toward the strategy target. A monthly schedule catches drift more often but generates more trades. Quarterly and annual schedules are quieter, with lower turnover, at the cost of allowing more drift between checks.

For a broadly diversified multi-asset portfolio, quarterly is a reasonable starting point. You can change the frequency at any time without disconnecting, and the change takes effect at the next scheduled run. The trade-offs between rebalancing frequencies, including timing approaches and cost considerations, are covered in the portfolio rebalancing strategy model guide.

Step five: review and approve the first rebalance

Once the connection is established, Acubic reads your current eToro positions, compares them against the target weights of the connected strategy, and constructs the minimum set of trades needed to close the gap. It presents that order set for your review. Nothing reaches eToro until you approve it.

You see each proposed trade before confirming. The first rebalance is a useful check: it shows how the tool reads your current positions and what it is planning to do with them. On a standard eToro connection, each subsequent scheduled rebalance also goes through this one-click approval before anything executes, and nothing further is queued while an approval is pending.

Which automation mode applies on a standard eToro connection

A standard eToro main-account connection offers two modes: Manual, where Acubic shows a checklist of the trades needed and places no orders, and One-Click Approval, where each scheduled rebalance is prepared and waits for your approval before anything is sent. Full Automatic, where scheduled rebalances run without a per-order prompt, is not available on a standard eToro connection; it requires an eToro sub-account, funded apart from your main balance. The full comparison, including when the eToro sub-account path is relevant, is in how to automate an eToro portfolio, and one-click vs full-auto rebalancing covers the decision between modes.

Adjusting settings after the connection

The three settings you configure during the connection flow can all be changed afterwards without reconnecting.

• Capital figure: expand or reduce the portion of the account Acubic manages. The change takes effect at the next rebalance.
• Rebalance frequency: switch between monthly, quarterly, or annually. The new frequency takes effect at the next scheduled run.
• Automation mode: switch between Manual and One-Click Approval; stop automation first, then switch.

Settings chosen during the eToro connection

Setting	Options	Can be changed later without reconnecting
Capital figure	Any portion of the account	Yes, from the next rebalance
Rebalance frequency	Monthly, quarterly or annually	Yes, from the next scheduled run
Automation mode	Manual or One-Click Approval (Full Automatic needs an eToro sub-account)	Stop automation first, then switch

How to disconnect

You can end the connection from inside Acubic, or revoke the access token directly from your eToro account settings. Either action stops Acubic from sending further rebalance proposals. Your existing positions are not affected: every holding stays exactly where it is. Acubic stops proposing trades; it does not close any of your positions.

Where to go from here

The connection is now established. Acubic will run a rebalance check at the next date your chosen frequency lands on and present the proposed order set for your approval.

For the complete reference on what the eToro connection sees, how it handles rejected orders, and how the managed-set boundary works in practice, the detailed guide is how Acubic works with eToro.

If you want to know which other tools could use the same access, and what the difference is between OAuth and eToro's user API keys, read what the eToro API can and cannot do. eToro's API getting-started page notes that a user-generated key is set to "Read" if you only need to access your portfolio data, or "Write" if you need to execute trades.

To review the integration page directly, including the full question list and setup walkthrough, go to the eToro integration page. If you are still building your first strategy, the portfolio builder is the starting point.
