What it can do to your account, and what it can't.

Coincruze runs a decision cycle on your portfolio, inside limits you set, and writes down why it did what it did.

Investing puts your capital at risk. You may get back less than you put in.

One cycle, five stages, in this order.

A cycle runs after the US market closes, and also when you add money and when your rebalance schedule comes round. Each stage can stop the cycle. Only the last one can place an order.

  1. 1

    Gather

    Your holdings, your available cash, the news signals published since the last run, your watchlist, and anything the last cycle deferred. This is the whole picture the decision is made from.

  2. 2

    Filter

    Everything you have ruled out is removed before the AI sees it: asset classes you do not want, sectors you have excluded, anything outside your stated universe. The model cannot pick what was never put in front of it.

  3. 3

    Reason

    Claude reads what is left alongside your strategy and proposes actions, each with a written reason. This is the only stage where judgement is exercised, and it happens inside the boundary the previous stage drew.

  4. 4

    Validate

    Every proposal is checked against your rules again, after the model has spoken. Position sizing is applied here. Anything that breaks a limit is rejected at this stage, not negotiated.

  5. 5

    Route

    What survives is either sent to your broker or held. Orders only go to Interactive Brokers while the market is open. The decision and its reasoning are written to your log whether or not anything was placed.

Separately from the cycle, the system polls your broker for what actually filled and at what price, and updates your positions from what the broker reports.

One decision, taken apart

Every move comes with the reasoning that produced it.

This is the record a cycle writes. It is the same card you see on your dashboard, and the same one kept in your decision log afterwards. Here is what each part of it is.

AI Rationale Example

Bought $1,240 of VTI (Vanguard Total Stock Market)

The model proposed a larger position. Sizing capped it at 20% of portfolio value, the ceiling Coincruze applies to any single holding. No technology candidate was considered this cycle: the sector was at 31.4% against the 30% cap you set.

Cash reserve reduced by the amount invested.

The action
What was bought, and how much of it. Stated first, because it is the thing that changed your account.
The rule you set
A 30% cap on technology. The sector was already over it, so no technology candidate was put in front of the model at all. Your rule ran before the reasoning did, not after it.
The rule we apply
A 20% ceiling on any single holding. This one is ours rather than yours, it applies to every account, and it is why the position is smaller than the model asked for. We say which rules are which.
The numbers behind them
31.4% measured against a 30% cap. What was measured and what it was measured against, both shown, so you can check the arithmetic rather than take it on trust.
Where the money went
The cash movement is accounted for. A decision that changes your cash position says so.
When, and where it is kept
Timestamped with its timezone and written to your decision log, which is where you go back to it.

You set the boundary once. It cannot step over it.

You set the boundary once. It cannot cross it.

The strategy is a set of limits, not a suggestion. Two stages of the cycle enforce them: one before the model reasons, one after.

What you set

Risk level and time horizon
How much volatility you will accept and how long you are investing for.
What you will own
Asset classes, sectors, geographies and ESG preferences, as a universe the system may pick from.
Sector caps
The largest share of your portfolio any one sector may reach, and how many holdings you want at once.
Rebalance schedule
How often the system checks whether your portfolio needs bringing back towards its target.

What it cannot do

Buy outside your universe
Anything you excluded is removed before the model is asked, so it is never a candidate.
Exceed a cap you set
A sector already at its cap takes no new buys, and a proposal that breaks a cap is rejected after the model makes it. The model does not get the last word.
Put more than 20% in one holding
A ceiling Coincruze applies to every account. It is ours rather than yours, and it is not currently adjustable.
Trade outside market hours
Orders reach your broker only while the market is open.
Move money out of your account
Coincruze can place orders inside your rules. It cannot withdraw cash, transfer assets, or send anything anywhere.
Change your rules
The strategy is yours to edit. Nothing in the cycle rewrites it.

Your broker, your account, your name.

Coincruze is not a broker and does not hold customer money. Your assets stay in your Interactive Brokers account throughout, and the access you grant is narrow enough to describe in a paragraph.

Where your assets are
In your own Interactive Brokers account, in your name, the entire time. Coincruze never takes custody of cash or securities, and there is no Coincruze account for your money to sit in.
How access is granted
You authorise the connection at Interactive Brokers, on their site, not on ours. We store the token that authorisation returns and nothing else about your credentials.
What that access is used for
Reading your positions and available cash, and placing orders that have passed your rules. That is the whole list.
What it cannot reach
The connection is used only to read positions and place orders. It does not withdraw money, transfer assets to another account, change your broker settings, or open new accounts.
How to revoke it
Disconnect from your dashboard at any time. The stored token is deleted, the scheduled cycles stop running against your account, and your holdings are untouched. You can also revoke the authorisation from the Interactive Brokers side.

And when it doesn't work.

Automated systems fail. A model returns something that cannot be parsed, a data feed goes quiet, a connection drops mid-run. The question that matters is not whether that happens, it is what the system does about it, and the honest answer is worth more to you than a reassurance.

A cycle that fails does not trade. Placing an order is the last stage of the cycle, and every failure before it stops the run there. A cycle that cannot complete leaves your portfolio exactly as it found it. There is no partial execution, no best guess, no half-applied strategy.

A failure is a decision too. When the model's response cannot be read, the run is written into your decision log marked as failed, with the error attached, alongside the runs that did something. A gap in the log would be the worst possible outcome: you would have no way to tell an unrecorded failure from a night the system chose to do nothing.

A failure on our side cannot reach your money. Your assets are at your broker, in your name. There is no state Coincruze can get into that moves them, freezes them, or makes them ours. The worst outcome of an outage here is that nothing happens to your portfolio that day.

Where this stands today

Coincruze has not yet run against a live account. Everything on this page describes what the system is built to do, verified against the code that does it, and we would rather say that than imply an operating history we do not have. When it has run, we will publish what it actually did.

Set the rules before anything runs.

Nothing is automated until you have seen the boundaries and agreed to them. Coincruze is pre-launch; the waitlist is where you say you want in.
