The client's idea
Zaringasht Investment works EURUSD on H4; the opening brief was: Write down our swing style as rules — faster than reading charts ourselves every night.
Project and starting point
Every night the team drew levels by hand and entries differed between members; the missing shared rule caused recurring arguments.
Solution architecture
A retracement rule with calculated levels, orders scheduled for the next session, and a fixed cap on concurrent positions.
The levels are calculated rather than drawn, which ends the debate about where the line goes. It matches how EURUSD is actually traded and can be tested against the data already available.
Why this design
The levels are calculated rather than drawn, which ends the debate about where the line goes. It matches how EURUSD is actually traded and can be tested against the data already available.
Implemented capabilities
Modules and components built: Trade scheduling + position cap.
Delivered output:
Swing retracement expert — EURUSD (H4)
Specification document and the rule-to-code mapping table
Full MQL5 source, commented
Test report: Six-year backtest
Parameter document and install guide (9 weeks)
Safeguards and risk control
Each module can be switched off on its own, and the exposure cap and daily stop are part of the expert rather than a later add-on.
Backtest and forward test method
Test method: Six-year backtest.
Testing runs in three stages: a backtest on historical data, limited optimisation inside the contract's scope, and a forward run with the parameters frozen.
Tools and stack: MQL5, six years of H4 data, monthly reporting.
Every figure from this project is published together with its measurement conditions: the data window, the tick model, the spread, the commission and the build of the executable. Without them a number cannot be compared with anything.
Publishable results
The team's nightly decisions became one rule set, and in the six-year test over 90% of trades followed it.
Limitations and cautions
Each module can be switched off on its own, and the exposure cap and daily stop are part of the expert rather than a later add-on.
Every test result depends on the quality of the historical data, the broker's spread and market conditions, and none of it is a promise about the future. Through a severe price gap or a broker disconnection a stop loss cannot be guaranteed, so behaviour in those conditions must be reviewed separately.
Our next-step proposal
The proposed next step is a reporting module wired into the trade journal.
