GridPro Panel — open-source grid trading EA with on-chart control panel
GridPro Panel is an open-source grid trading Expert Advisor for MetaTrader 5 with a built-in on-chart control panel. The full MQL5 source code is included, so every entry, averaging and exit rule is transparent – nothing is hidden inside a compiled ex5. It is intended as a readable, customizable grid framework with hard risk limits on top.
Requirements:
– MetaTrader 5, hedging account (the EA checks the account margin mode at startup and refuses to run on netting accounts)
– Any symbol; liquid low-spread symbols are recommended
Grid engine:
– Direction: both / buy only / sell only; the two sides are managed as independent baskets
– First order: immediate entry, or filtered by an optional signal – MA cross, RSI oversold/overbought, Bollinger Bands return, or Stochastic cross (the signal affects the first order only; further levels are added by the grid step)
– Averaging lots: fixed, martingale multiplier (default x1.5) or arithmetic increment (+0.01 per level), with a per-order lot cap and optional balance-based auto scaling of the initial lot
– Grid step: fixed points (default 300) or ATR-based dynamic step (H1, ATR 14, multiplier adjustable), with optional per-level step expansion (step grows every level)
– Maximum levels per side: 10 by default
Basket exit (each side is closed as a whole):
– Take profit in money (close the whole side at +$10 by default)
– Take profit in points from the average price
– Trailing take profit (activates at +$8, closes on a $3 pullback; takes over money TP when enabled)
– Optional basket stop-loss in money
Risk management (each limit can be enabled independently; the account drawdown stop at 30% and the minimum margin level at 300% are active by default):
– Account drawdown stop: close all positions and halt the EA
– Daily loss limit and daily profit target (auto-reset the next day)
– Basket stop-loss in money
– Maximum total lots cap
– Minimum margin level: stop opening new positions below the threshold
– Maximum spread filter
– Trading session filter for the first order (supports overnight sessions)
– Friday scheduled close-all (no weekend holding)
– Minimum interval between orders (protects against bursts of fills)
On-chart panel (dark theme, minimizable):
– Account card: balance, equity, floating P/L, drawdown %, spread, daily P/L
– Basket card: order count, lots and floating P/L per side; dashed average-price lines are drawn on the chart
– Runtime-editable parameters: first lot, grid step, step multiplier, lot multiplier, max levels, money TP, point TP, drawdown stop – type a new value and press Enter, no need to remove and reload the EA
– Buttons: pause/resume, buy now, sell now, close buys, close sells, close all
– Status line shows the exact reason whenever a risk rule blocks trading
Technical notes:
– The rounded-corner panel is rendered with per-pixel anti-aliased bitmap resources (see RoundRes() in the source), because native MT5 chart objects do not support rounded rectangles – the code can also serve as a reference for custom UI in MQL5
– Positions are filtered by magic number, so several instances can run on the same account without conflicts
Installation:
1. Open the .mq5 file in MetaEditor and compile (F7)
2. Attach the EA to a chart and enable Algo Trading
3. Test on a demo account first with the default 0.01 initial lot
Disclaimer: this EA is a trading framework for study and personal use, not a profit guarantee. Martingale-style averaging increases exposure during one-sided trends – understand every parameter and test on a demo account before any live use.
