Arbitragem MEXC Spot x Futuros

Highlights

How to Use

1. Review opportunities

   Open the Oportunidades tab to see the scanner table and set the minimum spread, maximum spread or sanity cap, and minimum 24h volume fields. The table refreshes on an interval and shows the coin, spread percentage, USDT difference, spot buy price, futures sell price, futures 24h volume and direction for each candidate, or an empty-state message when no pair matches the filters.

2. Price a trade

   Switch to Calculadora, choose whether to size by capital in USDT or by coin quantity, then set total capital, futures leverage and contract size. Enter the spot buy and futures sell prices plus spot and futures fee percentages, optionally fill the exit spot sell and futures buy-back fields, and press Recalcular to update the net profit, return on capital, required capital and the detailed breakdown table ending with the break-even buy-back price.

3. Configure the robot

   In the Robô tab edit the twelve parameters such as spread limits, capital per operation, leverage, minimum net profit, fees, scan interval and cooldown, keep the dry-run and auto-close checkboxes as desired, and save. Use Iniciar robô to start scanning and Armar operações automáticas to allow execution; the status chips show simulation, armed and running state, while Operações and Eventos list activity.

4. Set exchange keys

   Open Conta / API to enter a MEXC API key and secret. The page notes that the recommended approach is to define MEXC_API_KEY and MEXC_SECRET in the backend .env file, while keys typed here are held only in memory and not written to disk. Live trading additionally requires enabling live mode on the backend and turning off simulation in the robot panel.
