Larry Connor's - Double7 Mean Reversion System - Version 1.0
An enhanced implementation of Larry Connors' Double 7s strategy from "Short Term Trading Strategies That Work," designed to systematically capture high-probability short-term reversals in equity markets.
This elegantly simple system buys when price closes at a 7-day low and sells when it closes at a 7-day high. No indicators, no oscillators — just raw price action relative to its recent range. The strategy captures the tendency for short-term price extremes to revert with disciplined, rule-based execution.
Core Edge
When price closes at a 7-day low in an uptrending market, short-term sellers have pushed price to a local extreme. The Double 7s strategy captures the statistical edge that these short-term lows tend to be followed by bounces.
The simplicity of this signal is its greatest strength:
- No indicators or oscillators -- just raw price channel boundaries
- Fewer parameters means less curve-fitting and more robust performance
- One of the most transparent mean reversion signals available
- Adapts naturally to different price levels and volatility
Research Foundation
Based on Larry Connors' Double 7s strategy from "Short Term Trading Strategies That Work" (TradingMarkets, 2008). Connors is a widely published researcher in short-term trading strategies, known for his quantitative approach to systematic mean reversion. The Double 7s is one of his simplest and most robust systems, designed to work on equity indices and ETFs.
Strategy Rules
Long side:
- Entry: Close is at or below the N-day low (default 7) while price is above the SMA trend filter
- Exit: Close is at or above the N-day high (default 7)
Short side (disabled by default):
- Entry: Close is at or above the N-day high (default 7) while price is below the SMA trend filter
- Exit: Close is at or below the N-day low (default 7)
The default settings use Connors' original price channel exit only.
Optional Take-Profit and N-bar timeout exits have been added as enhancements for traders who want additional exit control — both are OFF by default. Entry and exit lookback periods are independently configurable per side.
Two entry modes are available:
- Standard: single entry per signal
- Aggressive: adds one additional position on deeper pullbacks
Typical System Behaviour
- High win rate (often 65 to 80 percent depending on market and settings)
- Small, consistent gains per trade
- Occasional drawdowns during strong trending markets
- Performs best on liquid equity indices and ETFs
This is a mean reversion system, not a trend-following strategy. It profits from short-term pullbacks rather than large directional moves.
Who This EA Is For
Ideal for:
- Professional Traders building multi-strategy portfolios
- Users familiar with systematic trading concepts

- Users seeking high-risk, high-return systems
Key Features
- Fully automated execution on MetaTrader 5
- Multi-symbol trading: up to 10 markets from a single chart
- Three position sizing modes: Fixed Lots, Dollar Value, and Account Percentage
- Automatic currency conversion for cross-currency instruments
- Independent entry and exit lookback periods per side
- Standard and Aggressive entry modes
- Optional enhanced exits: Take Profit (%) and N-Bar Timeout

Recommended Markets
Best suited for:
- US equity indices: S&P 500 (US500), NASDAQ 100 (NDX100/US100), Dow Jones (US30)
- Other liquid indices: Russell 2000 (US2000), ASX 200, DAX 40, FTSE 100
- Equity ETFs: SPY, QQQ, DIA, IWM, XLK
Individual equities can be traded but carry higher risk. Single stocks are inherently more volatile than indices and ETFs, and their downside risk during company-specific events is substantially larger. If trading individual equities, use conservative position sizing and always backtest first.
Not recommended for Forex or commodities unless specifically tested. Do not mix asset classes in the same EA instance.

Part of a Professional EA Series
This EA is one of 9 mean reversion strategies available from M.Wills. All target the same core edge — short-term pullbacks in trending markets — but each uses a different signal to identify when that pullback has gone far enough. Running multiple uncorrelated entry signals together can reduce drawdowns, improve consistency, and smooth equity curves.
The series includes:
- Connors TPS (scale-in with RSI)
- Connors RSI2 (RSI extreme readings)
- Connors Double 7s (7-day price channel)
- Connors Percent B (Bollinger Band %b)
- Bandy Naive MR (consecutive down days)
- Bandy PIRDPO (detrended price oscillator)
- Bandy RVI2 (relative vigor index)
- Bandy DV2 (close-to-midpoint momentum)
- Bandy Z-Score (statistical z-score)
Expert Advisor Settings
General Settings
Magic Number (default: 12345) - Unique identifier for this EA's trades. Use different numbers when running multiple EAs on the same account to prevent trade conflicts.
Trade Entry Mode (default: Open of Next Bar) - Controls when trades are executed:
- OPEN OF NEXT BAR: Places trades at the next bar open. Best for backtesting.
- CLOSE OF THIS BAR: Executes near the daily session close. Recommended for live trading.
- EXACT TIME: Executes at a user-defined time each day using the broker's server clock.
Exact Time (default: 23:54) - The time in HH:MM format used when Trade Entry Mode is set to Exact Time.
Timeframe (default: Current) - The chart timeframe for analysis. Daily is recommended.
Position Sizing
Sizing Mode (default: Lot Size) - Determines how position size is calculated:
- LOT SIZE: Uses a fixed number of lots per trade entry.
- TRADE VALUE $: Allocates a fixed dollar amount per trade, automatically converted to the correct lot size.
- ACCOUNT BALANCE %: Allocates a percentage of the current account balance per trade.
Position Size (default: 0.01) - The value applied to the selected sizing mode.
Max Margin % of Equity (default: 30.0) - Safety limit that caps how much margin a single trade can consume relative to account equity. Before every trade, the EA calculates the required margin and checks whether it would exceed this percentage of current equity. If it would, the trade is skipped and a message is logged to the Journal. This prevents accidental over-leverage on brokers with high minimum lot sizes. Set to 0 to disable.
Symbol Management
Additional Symbols (default: blank) - Comma-separated list of additional symbols to trade from a single chart (e.g. US500,NDX100,ASX200). Leave blank to trade only the chart symbol.
Max Symbols Open at Once (default: 2) - Maximum number of symbols that can have active trades simultaneously.
Long System
Enable Long (default: true) - Toggles long (buy) trading on or off.
Trend Filter: Price > SMA (default: true) - Long trades are only taken when price is above the moving average, ensuring trades align with the broader uptrend.
Trend Filter: SMA Period (default: 200) - The lookback period for the trend filter.
Entry: N-Day Low Lookback (default: 7) - The number of bars used to determine the lowest low for entry. A long entry triggers when the close is at or below this level.
Exit: N-Day High Lookback (default: 7) - The number of bars used to determine the highest high for exit. All long positions close when the close reaches or exceeds this level.
Exit: Take Profit % (default: 0.0) - Percentage-based profit target. Disabled by default — the price channel exit is Connors' original exit mechanism. Set to a percentage value to add a profit target as an additional exit layer.
Exit: N-Bar Timeout (default: 0) - Maximum bars to hold a position. Disabled by default. Set to a non-zero value to add a time-based exit.
Entry Mode (default: Standard) - Controls whether to take one entry or scale into additional positions on deeper pullbacks.
Aggressive: 2nd Entry Multiplier (default: 1.0) - When Entry Mode is set to Aggressive, this multiplier determines additional entry sizing.

Trend Filter: Price < SMA (default: true) - Short trades are only taken when price is below the moving average, ensuring trades align with the broader downtrend.
Trend Filter: SMA Period (default: 200) - The lookback period for the trend filter.
Entry: N-Day High Lookback (default: 7) - The number of bars used to determine the highest high for entry. A short entry triggers when the close is at or above this level.
Exit: N-Day Low Lookback (default: 7) - The number of bars used to determine the lowest low for exit. All short positions close when the close drops to or below this level.
Exit: Take Profit % (default: 0.0) - Percentage-based profit target for short positions. Disabled by default.

Metrics Start Date (default: 2000.01.01) - Starting date for performance calculations.
Alerts and Notifications
Chart Alerts (default: false) - Enable on-chart popup alerts when trade signals are generated.

Backtesting and Execution Notes
This strategy is designed for entry at the close of the trading day, when the signal is first identified. Backtesting research shows that entering at the close provides a measurable edge over waiting for the next day's open.
- Default mode: Open of Next Bar (required for MQL5 Market validation)
- Recommended for live trading: Close of This Bar, or Exact Time (1-2 minutes before market close)
- Set Exact Time to match your broker's daily close (e.g. 23:54 for a server that closes at 23:55)
Backtesting tips:
- Use "1 minute OHLC" or higher tick model for accurate results on daily bars
- Do not use "Open prices only" for daily timeframe strategies
- Close of This Bar and Exact Time modes may not function correctly in the Strategy Tester
Additional notes:
- Do not mix different asset classes in the same EA instance
- For Forex and Metals, use the Lot Size position sizing method only -- Trade Value and Account Percentage modes are designed for stocks and indices
Requirements
- MetaTrader 5 platform (Hedging or Netting account)
- Minimum recommended leverage: 1:30
- Daily timeframe preferred
- All symbols must be available in your broker's Market Watch

Risk Disclosure
This EA trades mean reversion setups using price channel boundaries. However, price can continue making new lows during sustained downtrends, and exits may not prevent losses during severe drawdowns. Backtests use historical data and do not account for slippage, partial fills, or changing market conditions. Proper position sizing relative to account equity is essential. Always test with demo accounts before trading live. Past performance does not guarantee future results.
