For Coinbase

Coinbase, without living in the API docs.

Coinbase moved to CDP keys, split Advanced Trade from the older endpoints, and scoped access to portfolios. That is adapter work, not trading. It is written against the Advanced Trade API as code in your project, and your keys stay on your disk.

The setup

The part that is not trading.

Nobody sets out to learn a key-signing scheme. It is the toll between an idea and a running process, and it belongs in code you can read once and then stop thinking about.

01State the strategy

Entries, exits, sizing and the loss you refuse to take, in plain language rather than a configuration file.

02The adapter carries the API

CDP keys, request signing, Advanced Trade endpoints and portfolio scoping are handled in an adapter written against Coinbase’s API, as a Model Context Protocol server in your repository.

03Keys scoped and local

Credentials sit on your machine, tied to the one connection that uses them, and never travel when a Stack is shared.

04Backtest, then build routing deliberately

Test against history first. Live order routing is built and tested before it touches capital, then run at a size you would not mind being wrong about.

Held to account

Why there is no supported-exchanges list.

Tools in this category ship a fixed roster of exchanges, and the roster is what the subscription pays for. QuantIDE ships the layer beneath it.

Not a pre-built integration

Coinbase is not a feature we maintain. The adapter is written against its API in your project and is yours to read, fix and keep. The day you want a venue nobody has connected, it is connected the same way.

Rotate a key without rewriting anything

Coinbase keys are meant to be rotated, and the usual cost is hunting down every place the old value was pasted. Here a credential belongs to the single connection that uses it: replace it once and nothing else moves.

Fees are part of the result

Plenty of crypto strategies look profitable until maker and taker fees are applied to every fill. Backtests carry costs, and when the margin is thinner than it first appeared, you are told rather than shown a flattering curve.

Due diligence

Coinbase, the questions asked first.

Do I need to understand the Coinbase API?

No. Coinbase has moved key formats and split Advanced Trade from its older endpoints, which is the kind of change that consumes an evening and produces no trading. You describe the strategy; the connection is an adapter written against the API, in your project, that you can read whenever you want to.

Do I have to write the code myself?

No. Describe what you want and it is written as readable source you own, in whatever language suits the job, since nothing here is tied to one. You can open it, change it, keep it, and ask what any part of it does.

Does it trade live on Coinbase out of the box?

No. Nothing trades live out of the box. Order routing is built against the Advanced Trade API with your keys, and tested before it touches capital.

Which historical data is used for backtests?

Yahoo Finance history is the bundled source, and it is cached on your disk. Coinbase’s own market data, or any other vendor, is connected through an adapter like everything else.

Where do my API keys live?

On your own machine, scoped to the single connection that needs them. They are never bundled into anything you share: a Stack you hand to somebody else carries the setup, never your credentials.

Can I trade anything besides crypto?

Yes. There is no venue list to be limited by. Equities, futures and forex brokers are connected the same way: an adapter written against their API, in your project.

Does my computer need to stay on?

The app does not have to stay open: a running process is supervised and survives you closing QuantIDE. The machine does need to be on and online. If you want it running around the clock, that is a machine you control, not a runtime we host.

What does it cost?

One monthly plan: no tiers and nothing to unlock. Current terms are shown before you download rather than printed here. It runs on Windows, macOS and Linux, and you can cancel anytime.

Where to go from here.

You already have the account. Test the idea before the key.
