Crypto bot - $30 max project budget

Fee Structure: Leveraging MEXC’s 0% spot fee promotion for both Maker and Taker orders.
Infrastructure: Python-based bot using the CCXT library hosted on a Tokyo-based AWS/cloud server for minimum latency to MEXC's matching engine.

Trade Execution Logic
Entry (The Breakout):
Order Type: Stop-Limit Buy.
Trigger: Price rises +4 points from start (e.g., ).
Price Guarantee: Limit price is set exactly at the trigger () to avoid buying higher.
Monitoring & Safety:
Gap Protection: If the market price exceeds the limit without filling, the bot cancels the order immediately to avoid "chasing."
Partial Fill Handling: If only a portion fills, the bot cancels the remainder and adjusts the exit size to match the filled amount.
Exit (The Scalp):
Take Profit: Limit Sell at +2 points from entry ().
Stop Loss: Stop-Limit Sell at -2 points from entry ().


Technical Implementation
Connection: Use MEXC WebSockets for real-time price streaming instead of REST API polling to reduce latency.
Rate Limits: Ensure the bot stays within MEXC's limit of 5 orders per second to avoid API bans.
Order Sync: Use the post Only parameter for Limit Sells to ensure they stay on the book as Maker orders, further protecting against unexpected fee changes.
