Upwork Job – Development of an API Connection for Gate.io Futures Trading

Requirements:

A developer is required to establish a working API connection to the Gate.io Futures API and integrate a simple trading interface with the following features.

Important Notes (Avoidable Issues):

CSP (Content Security Policy): Direct API requests from the browser are blocked.

Fetch Restrictions: Browsers block API requests to external domains.

Tampermonkey: Does not work, as it still operates within the browser environment.

Cloudflare Protection: Gate.io uses security mechanisms that block certain requests.

👉 The solution must run outside the browser (e.g., through a local proxy or a server bridge).

Proposed Solution:

The solution consists of two components:

Backend (Runs outside the browser):

A local server (e.g., Node.js, Python Flask/FastAPI, or Go) provides an API.

This server handles API requests to Gate.io and bypasses browser restrictions.

Frontend (Runs in the browser):

A web interface (HTML/CSS/JavaScript or React/Vue) sends requests to the backend and receives API data.

The backend manages communication with Gate.io, while the UI remains in the browser.

🚀 Advantages of this Solution:

The browser does not communicate directly with Gate.io but only with the backend.

The backend fetches data from the Gate.io API and passes it to the frontend.

This approach avoids CSP and fetch restrictions since the browser only interacts with a trusted local server.

Alternative Solution

If a backend is to be avoided entirely, a standalone application (e.g., using Electron.js or PyQt) could be developed, integrating both UI and API access locally.

However, if the UI must remain in the browser, the frontend-backend separation is the best approach.

Task Description:

Establish a connection to the Gate.io Futures API.

Implement a start button to activate the strategy.

Include quantity input fields for buy and sell.

Add a confirmation on/off button to control buy and sell separately or together.

Automated order placement:

Open one sell and one buy trade.

Increment input field for order distances:

If the price drops → Place a limit buy order below the last buy price (with a distance of X).

If the price rises → Place a limit sell order above the last sell price (with a distance of X).

Take Profit (TP) settings:

TP field for % profit (with selection for the chosen strategy).

TP field for $ profit.

Hedging function:

Hedge Lowpoint – A hedge is set at this price to neutralize open trades.

Hedge Highpoint – A hedge is set at this price to neutralize open trades.

📌 Expected Solution:

API integration must be stable and secure.

UI components should be easy to use.

The solution must bypass browser restrictions effectively.

Only apply if you have experience with API workarounds for these security mechanisms.
