Pull Back Strategy with TurtleTrend

Turtle Trend Pullback EA — a channel-breakout-and-pullback reversal system with fully ATR-based risk management (SL/TP/breakeven). Walk-forward validated on EURUSD, AUDUSD, USDJPY and XAUUSD (H1) using out-of-sample cross-validation, not just curve-fitted backtests.

	SL	TP	BE	ATR_PERİOD	CL- LENGHT
EURUSD	3,50	5,50	1,50	6,00	6,00
AUDUSD	2,50	3,50	2,50	6,00	42,00
USDJPY	3,50	7,00	2,50	18,00	2,00
GOLD	4,50	4,50	2,00	6,00	8,00

Turtle Trend Pullback EA

A rules-based trend-reversal system built on Donchian channel logic, validated with out-of-sample testing across multiple instruments.

Strategy Logic

This EA is based on a "Turtle Trade Channel" concept: it tracks the most recent breakout direction using a rolling high/low channel. Instead of trading the initial breakout, it waits for price to pull back to the channel line and get rejected there — confirmed by a full candle close in the reversal direction. This pullback-rejection approach aims to enter with better risk/reward than chasing the initial breakout.

All exits are ATR-based: stop-loss, take-profit, and a breakeven trigger are each calculated as a multiple of the current Average True Range, so position sizing adapts automatically to each instrument's volatility. Only one position is held at a time, and lot size is calculated from a fixed percentage risk of account balance.

Validation Methodology

Unlike many retail EAs that are simply curve-fit to a single backtest, this system was optimized and validated using a two-stage process:

• Signal parameters (channel length, ATR period) and exit parameters (SL/TP/breakeven multipliers) were optimized separately to reduce overfitting risk.
• Every candidate parameter set was tested across multiple independent in-sample / out-of-sample splits (not just one), and only kept if performance stayed consistent across all of them.
• Parameter sets that looked excellent on a single test but collapsed on an untouched forward-testing window were explicitly discarded — including on pairs where no reliable edge could be found (this EA is not recommended for GBPUSD or USDCAD based on this testing).

Tested & Validated On

• EURUSD (H1)
• AUDUSD (H1)
• USDJPY (H1)
• XAUUSD / Gold (H1)

Each instrument uses its own optimized parameter set — this is not a "one-size-fits-all" configuration copy-pasted across symbols.

Key Features

• Fully automated, single-position trend-reversal system
• ATR-based stop-loss, take-profit, and breakeven management
• Percentage-risk position sizing (adapts lot size to account balance)
• Optional time-based trading filter (avoid low-liquidity/rollover hours)
• Magic number and comment tagging for easy trade tracking
• Clean, lightweight code — low CPU/latency footprint

Inputs

• Channel length & ATR period (signal parameters, per-symbol)
• SL / TP / breakeven ATR multipliers (risk parameters, per-symbol)
• Risk per trade (% of balance)
• Trading time window filter
• Magic number, slippage, trade comment

Recommended Setup

• Timeframe: H1
• Use the parameter set matching the traded symbol (see product comments/manual for per-pair settings)
• Recommended minimum account balance and leverage will depend on your broker's contract specification — test on demo first
• Broker with tight spreads and reliable execution recommended (ECN/raw-spread account preferred)

Risk Disclaimer

Past performance, including backtest and walk-forward results, does not guarantee future results. Forex and CFD trading carries a high level of risk and may not be suitable for all investors. Always test on a demo account before live deployment, and never risk capital you cannot afford to lose. This EA does not enforce any prop-firm-specific rules (daily loss limits, consistency rules, etc.) — verify compatibility with your account's terms before use.
