Turtle System 2
USDJPY D1 intrabar channel-breakout variant with Wilder-N stop and channel exit.
Selected public preset
ResearchMode 1; Variant 1; MagicNumber 26092142; RiskPercent 0.25; MaximumSpreadPips 2; RoundTripCommissionPerLot 7 (a sizing estimate, not a charged test fee); CampaignSession 0; CampaignSessionPolicy 1.
Rule and risk mechanics
Variant 1 enters one tick above the previous 40 completed daily-bar high or below its low. It uses 20-period Wilder N from completed D1 true ranges, a 2N stop and no fixed target. A held long exits when bid is at or below the previous 20-day low; a held short exits when ask is at or above the previous 20-day high. Source controls include 0.25% equity risk, a 1.5% daily brake and 2-pip spread gate.
Relationship to the strategy library
Related only by channel-breakout family: Donchian 20/10 Breakout is D1 close-based 20/10 with a 60-bar holding contract; Turtle uses intrabar 40-day entry, 2N and 20-day exit. See the legacy EA map for mapping scope.
Follow-up: ordinary long-channel exit observed
The unchanged selected public EA bought 0.01 lots of USDJPY.TFQ1 at 148.812 on 5 February 2024 at 02:37:09 broker time. On 7 March at 10:02:38 it sold at bid 147.930, the previous 20-completed-day low. This was an ordinary strategy close, not a tester-end close. The 2N stop at 146.077 was lower. A later 19 March entry was closed by the tester on 29 March and is counted separately.
The fixed extension ran from 1 February inclusive to 1 April exclusive on D1, with broker UTC+2 and UTC+3 after the US daylight-saving transition. It processed 5,869,589 real bid/ask ticks: 2 entries, 1 ordinary long-channel exit and 1 tester-forced close. Price P/L was −$3.20; recorded swap +$2.34; final balance $9,999.14 from $10,000. Added commission and delay were zero; financing history is unverified. This is functional path evidence, not a performance qualification.
The source initializes Wilder N from 201 completed daily bars. Its historical input includes excluded broker dates 22, 25–27 and 29 December 2023 and 1–2 January 2024. Those warmup limitations are retained; the February–March decision interval has no release exclusions. The short-channel exit, stop execution, risk sizing and restart behavior remain unproved by this case.
Earlier February 2024 observation
The receipt recorded 1 entry and a tester-forced close. It demonstrates lifecycle only; an ordinary channel exit was not observed. The approved new diagnostic window is 2024-02-01 inclusive to 2024-03-01 exclusive, on USDJPY.TFQ1 D1, with Model 4, a USD 10,000 deposit and 1:100 leverage at broker UTC+2. It added no commission or delay; recorded native swap history is unverified. It is separate from older archived broker charts and reports. It is not a profitability, restart, or full-rule-coverage result.

How this strategy works
- Variant 1 enters intrabar when bid crosses at least one symbol tick beyond the preceding 40 closed D1-bar channel. Variants 0/2 use 55/80 bars.
- N is calculated as a 20-period Wilder-smoothed true range and the initial protective stop is 2N.
- No pyramiding is used. Exit a long when bid reaches the opposite 20-day channel low, or a short when ask reaches its high; there is no time exit.
The selected configuration uses USDJPY / D1, variant v1-s0. All indicator and session values used by this build are listed in the preset editor.

Adjust the strategy preset
MT5 also validates parameter combinations and may reject incompatible inputs. Session modes use local London, New York and Tokyo hours. Broker-time conversion uses the configured winter UTC offset and DST rule. A session filter limits eligible entries; it does not change the underlying strategy signal or create trades where none qualify. Policy 2 also closes before the chosen session ends.
Install and reproduce the archived broker test
- Download and extract the ZIP. Copy
TFPublishedResearch.ex5intoMQL5/Experts/TradeForexin the MT5 data folder. Keep MQ5 and all MQH headers together if compiling. - Open Strategy Tester, select the EA, USDJPY and D1. The build rejects normal chart execution.
- Load the included
selected-test.setor a preset downloaded above. Symbol, chart timeframe, dates, deposit and tick model are tester settings outside the .set file. - For confirmation choose “Every tick based on real ticks”, EUR 10,000, 1:30 leverage and 100 ms delay. Use 2025.09.01–2026.09.01 or 2019.01.01–2026.09.21; retain the generated report and Journal.
- Allow MT5 to obtain the available broker history. Compare actual date coverage, costs, trade count and history quality; a later download or different broker server can change the result.
Read the general MT5 installation guide; this package’s tester-only restriction takes precedence over normal chart-activation steps.
Limits of the archived broker results
- Daily channels depend on broker daily boundaries.
- No pyramiding is an explicit adaptation.
- These are retrospectively selected historical tests. Development, validation and review periods overlap previously inspected history; this is not a fresh independent holdout.
- The balance plots show realized outcomes. Equity drawdown includes floating positions and must not be inferred from the balance line alone.
- Available native ticks and fallback are accepted. Missing ticks, historical spread paths and cost assumptions limit confidence; profitable history does not guarantee future profitability.
- RiskPercent is an entry-sizing estimate, not a hard loss cap. Costs, gaps and slippage can exceed that estimate; some legacy sizing excludes transaction costs.
Additional cost stress adds 25% of the absolute commission and swap amounts: 12-month stressed net EUR -110.27; long-period stressed net EUR +70.69. This is not a full spread or slippage stress.
