Strategy rules

How this strategy works

  1. 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.
  2. N is calculated as a 20-period Wilder-smoothed true range and the initial protective stop is 2N.
  3. 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.

Original Turtle trading rules. The download is a documented research adaptation; results from the reference do not establish results for this EA.

Your next test

Adjust the strategy preset

Adjust the actual MT5 inputs below, then download a .set file. Load it through Strategy Tester → Inputs → Load. The EA ZIP includes source code and the compiled file.

Selected tested preset loaded.

Research session controls · 6 inputs

Changes apply to your downloaded file. They do not change the published tests.

Preview the .set file

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 test

  1. Download and extract the ZIP. Copy TFPublishedResearch.ex5 into MQL5/Experts/TradeForex in the MT5 data folder. Keep MQ5 and all MQH headers together if compiling.
  2. Open Strategy Tester, select the EA, USDJPY and D1. The build rejects normal chart execution.
  3. Load the included selected-test.set or a preset downloaded above. Symbol, chart timeframe, dates, deposit and tick model are tester settings outside the .set file.
  4. 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.
  5. 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.

What these results can establish

  • 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.
