Grid Classic (Renko Chart) is an automated Expert Advisor (EA) implementing a buy-direction grid trading strategy. It initiates trading by placing a buy order at the current market price, then systematically sets Buy Limit orders below this price at intervals defined by the user-specified grid step (measured in USD). The lot size for each subsequent order increases according to a configurable Martingale multiplier, with a maximum lot size limit to manage exposure.
The system continuously monitors the total net profit of all open orders and closes all positions immediately once the combined profit turns positive, then automatically restarts the cycle. This process runs fully automated 24 hours a day, five days a week.
Key configurable inputs include initial lot size, Martingale multiplier, maximum lot size, grid step distance, and the maximum number of grid orders. The strategy is designed primarily for trading in indices, commodities, and the XAUUSD symbol, and is noted as suitable for proprietary firm trading environments.
The Grid Classic EA focuses exclusively on buy trades and allows users to customize grid spacing and recovery logic within the grid system framework.
