<br>Grid Master Pro: Universal Grid Trading System for MetaTrader 5
<br>
<br>For professional traders wishing to maximize profits on sideways market movements, grid trading system represents a powerful tool for systematic income generation. Grid Master Pro is a revolutionary automated grid trading platform combining an intelligent price grid construction system with comprehensive position management, including trailing stops, break-even functions, and complete control over daily limits while maintaining flexibility for various market conditions.
<br>
<br>Grid Trading Concept and Its Advantages
<br>
<br>Grid Master Pro uses grid trading methodology, in which the system automatically places a series of pending orders at certain distances from each other, thus creating a virtual price grid. When price reaches one of these levels and triggers the pending order, the system immediately opens a position. The advantage of this approach is that the system can capture profits on every price movement in a sideways trend, generating income even when the market is consolidating without obvious directional movement.
<br>
<br>The system automatically places pending orders both above (BUY_STOP) and below (SELL_STOP) the current price, forming a two-way grid. Each time price reaches one of the grid levels, the corresponding order triggers and a new position opens. The system manages each position independently, applying set stop-loss and take-profit levels for risk control and profit protection.
<br>
<br>System Architecture with Control Panel
<br>
<br>Grid Master Pro includes a built-in real-time control panel that displays key trading activity statistics. The panel shows daily profit (Day Profit), weekly profit (Week Profit), monthly profit (Month Profit), and total profit (Total Profit), updating these values in real-time as positions close. The “Close Profitable” button allows the trader to close all profitable positions with one click, providing quick profit-taking.
<br>
<br>The panel is fully customizable in background color, text color, and display style. The ShowPanel parameter allows disabling the panel if needed while maintaining functionality of all other system functions. The system uses custom classes for drawing interface elements (CCellText, CCellEdit, CCellButton), ensuring easy extension and panel modification.
<br>
<br>Price Range Calculation and Update System
<br>
<br>Grid Master Pro includes an intelligent system for automatic price range calculation where grid pending orders will be placed. The AutoRange parameter allows selecting automatic calculation mode: RANGE_DAILY uses minimum and maximum of daily price movement, RANGE_WEEKLY uses weekly range data, RANGE_MONTHLY uses monthly range data. RANGE_CUSTOM mode allows setting the range manually by specifying MinimumPrice and MaximumPrice.
<br>
<br>The system uses built-in MQL5 functions to obtain historical OHLC (Open, High, Low, Close) data for the necessary period and calculates the exact price range where grid pending orders will operate. When necessary, the system automatically recalculates the range on each new hourly bar, ensuring constant adaptation to current market conditions.
<br>
<br>Intelligent Pending Order Placement
<br>
<br>Grid Master Pro implements an advanced pending order (Pending Orders) placement system considering many limitations and conditions. The system automatically checks the minimum distance between grid levels (GridStepPips), ensuring optimal pending order distribution. The NumberOfOrders parameter determines how many pending orders will be placed in the grid both above and below current price.
<br>
<br>The system calculates the minimum distance from current price required for placing BUY_STOP and SELL_STOP orders, considering broker freeze level and stop level. The TrySendOrder function checks the validity of each order before sending, ensuring all broker conditions are met. The MaxSpreadPips parameter limits pending order placement during high spread periods, preventing position opening under unfavorable conditions.
<br>
<br>Risk Management and Position Sizing System
<br>
<br>Grid Master Pro includes two main lot sizing systems. LOTMODE_FIXED mode uses fixed position size (FixedLotSize), providing constant trading volume for each trade. LOTMODE_PERCENT mode automatically calculates lot size based on selected risk level (RISK_LOW, RISK_MEDIUM, RISK_HIGH) and account balance.
<br>
<br>When using the percentage method, the system calculates position size such that the maximum loss on one position if stop-loss is triggered does not exceed the set percentage of balance. The system automatically normalizes the calculated lot according to broker requirements (minimum and maximum size, increase step). Before each position opening, the system checks sufficient free margin availability (CheckMarginConditions function), preventing over-leverage and account suspension.
<br>
<br>Trailing Stop System for Profit Maximization
<br>
<br>Grid Master Pro includes an advanced trailing stop system (Trailing Stops), which automatically moves the stop-loss level higher as the profitable position develops. The TrailingStartPips parameter defines minimum profit in pips at which trailing stop is activated. The TrailingDistancePips parameter sets the distance in pips at which the stop-loss is placed from current price. The TrailingStepPips parameter defines minimum change in pips necessary to move the stop-loss.
<br>
<br>The DoTrailing function checks each open position for reaching target profit and automatically moves the stop-loss to higher levels, locking in gains and protecting accumulated profits from price reversals. The system uses the ValidateSL function to check that the new stop-loss level complies with broker requirements before setting it.
<br>
<br>Break-Even Function for Eliminating Losses
<br>
<br>Grid Master Pro includes a break-even function which automatically moves the stop-loss to entry point or slightly above when a position reaches a certain profit level. The BreakEvenStartPips parameter defines minimum profit in pips at which break-even function is activated. The BreakEvenOffsetPips parameter sets additional offset above entry point where break-even stop-loss is placed.
<br>
<br>The DoBreakEven function checks each position and when condition is met, moves stop-loss to break-even, eliminating possibility of losses on that position. This function is especially useful when trading sideways markets where there may be many opportunities for stop-loss hits.
<br>
<br>Daily Limits and Position Quantity Control System
<br>
<br>Grid Master Pro includes trading operation quantity control system through the DailyLimit parameter. When DailyLimit mode is enabled, the system limits the maximum number of entries (buy/sell trades) during one trading day, defined by the MaxOrdersPerDay parameter. The system automatically counts entries in the current day (CountDealsToday function) and stops placing new pending orders when the limit is reached.
<br>
<br>The Max_Orders_Per_Symbol parameter limits the maximum number of simultaneous open positions and pending orders for one symbol, providing risk concentration control. The system tracks total active orders (g_total_orders variable) and uses OnTradeTransaction functions for correct counter updates when positions and orders are opened, closed, or deleted.
<br>
<br>Trade History Visualization on Chart
<br>
<br>Grid Master Pro displays the entire history of executed trades directly on the price chart using color coding and information labels. Entry positions are marked with arrows code 220, exit positions are marked with arrows codes 221 and 222. The system uses different colors for buys (BuyTradeColor, default green) and sells (SellTradeColor, default red).
<br>
<br>Each closed position is accompanied by a text label showing the final trade result (profit or loss) in monetary terms. The system connects entry and exit trades of the same position with dashed lines colored DodgerBlue for visual tracking of the complete trading cycle. The TradeFontSize parameter controls the font size of results, ensuring readability at various chart scales.
<br>
<br>Application on Major Trading Instruments
<br>
<br>Grid Master Pro is effectively applied to major currency pairs EURUSD, GBPUSD, USDJPY, AUDUSD due to regular sideways movements and predictable consolidation patterns on these pairs. On precious metal XAU (gold), the system demonstrates high effectiveness due to frequent sideways channels and volatility ideal for grid trading. On energy commodities WTI and Brent, the system analyzes characteristic volatility cycles driven by supply and demand.
<br>
<br>On cryptocurrencies BTC and ETH, the system operates with high accuracy due to technical price behavior and frequent sideways movements during consolidation periods. The system easily adapts to various time periods and can operate on daily, four-hour, or hourly bars while maintaining reliability thanks to its entire built-in checking and filtering system.
<br>
<br>Obsolete Pending Order Cleanup System
<br>
<br>Grid Master Pro includes an automatic obsolete pending order cleanup function (CleanupPendingOrders), which deletes pending orders if price has moved far from the placement level. This function prevents accumulation of irrelevant orders that will never trigger due to price shifting beyond the grid range. The system checks the distance between current price and pending order placement price and deletes the order if this distance exceeds 2x GridStepPips value.
<br>
<br>Trading Direction Flexibility
<br>
<br>Grid Master Pro provides complete flexibility in choosing trade direction through the GridTradeDirection parameter. GRID_BUY mode places only BUY_STOP pending orders above current price, creating an uptrend grid. GRID_SELL mode places only SELL_STOP pending orders below current price, creating a downtrend grid. GRID_BOTH mode creates a two-way grid with BUY_STOP and SELL_STOP orders, allowing the system to extract profits from price movements in both directions.
<br>
<br>Debug Mode for Detailed Analysis
<br>
<br>Grid Master Pro includes DEBUG_MODE (DEBUG_MODE = false by default), which outputs detailed logs of all system actions to the terminal journal. When DEBUG_MODE = true is set, the system outputs information about pending order placement, position closing, active order count, and other key events, facilitating analysis and algorithm optimization.
<br>
<br>Strategy Implementation and Optimization
<br>
<br>Before implementing Grid Master Pro on live accounts, traders should conduct testing on historical data using the built-in MetaTrader 5 Strategy Tester. It is recommended to start with a small number of pending orders (NumberOfOrders = 2-3) and small grid step (GridStepPips = 30-50) for testing the logic. After successful testing, the number of pending orders and step size can be gradually increased.
<br>
<br>On a demo account, it is recommended to test the control panel operation, trailing stop and break-even functions, verify correct visualization on the chart. Starting on a real micro account with minimum lots allows testing algorithm behavior under real trading conditions without significant financial risk. As experience accumulates and parameters are adjusted to specific trading conditions, the system can be gradually scaled.
<br>
<br>Conclusion
<br>
<br>Grid Master Pro represents a comprehensive solution for automated grid trading, combining intelligent price grid construction, multiple position management, and complete risk control. The built-in real-time control panel, trailing stop and break-even functions, daily limits system, and trade history visualization provide complete control over the trading process. Advanced margin checking, spread management, and obsolete order cleanup systems guarantee reliable operation under various market conditions. Whether you specialize in sideways markets or seek an additional income source beyond trend trading, this system provides proven grid trading methods with complete automation, advanced position management, and reliable capital protection necessary for success in modern financial market trading.
