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. import ccxt import time exchange = ccxt.mexc({'apiKey': 'YOUR_KEY', 'secret': 'YOUR_SECRET'}) symbol = 'XRP/USDT' tick = 0.0001 # 1 point def run_scalp(): # 1.
