Overview
Patient King is a mean-reversion grid Expert Advisor originally developed and optimized for AUD/CAD on the 5-minute chart. It waits for price to stretch away from its average before entering, then manages a capped grid of positions with ATR-based spacing until the basket reaches its take-profit target. Built-in risk controls include drawdown protection, a news filter, and a hard cap on grid stacking to limit exposure.
Key Features
- Auto Lot Sizing — choose a risk level (Very Low to Extreme) and let the EA size positions automatically, or set a fixed lot manually
- ATR-Based Dynamic Grid — grid spacing adapts to current volatility instead of using fixed pip distances
- Grid Level Cap — configurable maximum number of grid positions per side, preventing unbounded position stacking
- News Filter — automatically pauses trading around high/medium-impact news for AUD, CAD, USD, and other selected currencies, with configurable buffer times. News data is pulled live from the ForexFactory economic calendar
- Trading Schedule Controls — restrict trading to specific days and server-time hours
- Drawdown Protection — monitors floating drawdown and closes all positions if a maximum threshold is breached
- Locking & Pause Logic — widens grid spacing and reduces exposure automatically when conditions turn unfavorable
- Live On-Chart Dashboard — real-time panel showing open orders, lots, P/L, basket take-profit levels, spread, drawdown, and news status per side (buy/sell)
Recommendations & Settings
Minimum Balance
Depends on the Auto Lot risk level selected — ranges from $300 (Extreme risk) up to $2,400 (Very Low risk) per 0.01 lot of exposure. Lower balances with higher risk settings mean larger lot sizes relative to account size and less room for the grid to run before drawdown protection intervenes; we recommend starting with a balance on the higher end of your chosen risk tier, and using a more conservative risk level (Low-Medium or lower) on smaller accounts.
Account Type
Hedging-enabled MT4 account (the standard account type at most MT4 brokers). Required because the EA can hold multiple same-direction grid positions simultaneously on one symbol.
Recommended Timeframes
M5 (5-minute) — the timeframe the EA was designed and optimized on. Other timeframes can be tested at your own discretion but are not officially supported.
Recommended Pairs
AUD/CAD (primary, optimized pair). Other pairs can be tested but performance is not guaranteed outside this configuration — always backtest/demo first before switching pairs.
Recommended Default Settings
| Setting | Default | Notes |
|---|---|---|
| Auto Lot Risk | Low-Medium ($1,200) | Lower $ value = larger lot size per balance; adjust to your risk tolerance |
| Max Grid Levels | 10 | Caps how many positions the grid can stack per side |
| Max Drawdown % | 50% | EA closes all positions and stops if floating drawdown hits this |
| Max Spread | Disabled (0) | For live trading, we recommend setting this to your broker's typical spread + buffer (e.g. 20–30 points on AUD/CAD) |
| Slippage / Max Slippage | 50 / 200 points | Can be tightened for brokers with fast, reliable execution |
| Trading Schedule | Mon–Fri, 0–24 (server time) | Adjust to avoid illiquid session hours if desired |
Setup Instructions
- Attach the EA to an AUD/CAD, 5-minute chart
- Enable AutoTrading in MT4
- To use the News Filter, go to Tools → Options → Expert Advisors and add https://nfs.faireconomy.media to the list of allowed URLs for WebRequest — without this, the news filter will not receive calendar data
- Review and adjust the risk/lot-sizing inputs to match your account size and risk tolerance
- Test on a demo account before running live
Risk Disclaimer
This is a grid-based trading strategy. Grid systems can accumulate multiple open positions during extended adverse price moves, which increases drawdown and margin usage. Past or backtested performance does not guarantee future results. Please test thoroughly on a demo account first and use position sizing appropriate to your risk tolerance. No trading system, including this one, can guarantee profits, and you may lose some or all of your invested capital.
