Engine Smart DSignalROI BOJ

ENGINE SMART D-SIGNAL + ROI MT5 EA

ENGINE SMART D-SIGNAL + ROI MT5 is a multi-symbol Expert Advisor for MetaTrader 5 built around D1 channel-based D-Signal logic and an optional Bank of Japan / ROI event calendar filter. The EA combines technical channel signals, tick-direction confirmation, controlled grid logic, partial target exits and professional risk-control modules in one system.

The strategy is especially focused on JPY pairs and Bank of Japan interest rate decision periods, because these market windows often create a combination of elevated volatility, directional repricing and technically visible overextension around channel boundaries. Instead of trading every market condition in the same way, this EA separates the JPY/BOJ event model into a dedicated strategy block, giving the user a focused tool for testing and trading a very specific market behavior. 

Important: this product does not guarantee profit. All trading involves risk. The EA should be tested in the Strategy Tester and on a demo account before live use.

MAIN IDEA

The EA analyzes selected symbols using a D1 TMA/D-Signal channel. The channel defines the upper boundary, lower boundary and median line. Entries are based on the EA’s internal D-Signal conditions, including channel location and tick-direction confirmation. The logic is not based on a simple static two-point trendline. The visual channel is calculated and drawn as a full historical channel to help the user understand the real trading logic during live trading and visual backtesting.

The Expert Advisor can work in two main modes:

1. Technical mode: the EA can trade according to the technical D-Signal logic without calendar restriction.

2. BOJ/ROI calendar mode: the EA trades only inside the configured window around Bank of Japan interest rate decision dates.

WHY THIS STRATEGY IS SEPARATED AS A DEDICATED TOP MODEL

This EA is not a generic “trade everything all the time” robot. The core idea is to isolate a special market situation: JPY pairs around Bank of Japan rate-decision windows.

This approach is powerful because:

• JPY pairs can react strongly around monetary policy events.
• BOJ decision periods often create fast repricing, false breakouts and expanded channel movement.
• The EA combines event timing with technical overextension instead of using only news or only indicators.
• The D1 channel helps filter noise and gives the strategy a structured price context.
• Tick-direction confirmation reduces the chance of opening only because price touched a level visually.
• The Target 1 / Target 2 system allows partial profit-taking and controlled continuation.
• The visual channel and signal arrows make the logic transparent in the Strategy Tester.

This is the reason the strategy is presented as a dedicated premium model: it focuses on a recognizable market phenomenon and gives the trader tools to analyze, test and control it.

VISUALIZATION

The EA includes optional chart visualization:

• Full upper channel line
• Full lower channel line
• Optional median line
• BUY and SELL signal arrows
• Configurable colors, widths and update frequency

The visualization is designed to be lightweight. It does not recalculate or redraw unlimited history on every tick. The number of visual bars and update interval are limited by input settings.

TRADING WINDOW AND CALENDAR SETTINGS

The EA trades only within the event window around configured calendar dates.

DaysBeforeEvent

Number of days before the BOJ event when trading is allowed.

TradeAfterEvent

Allows trading after the event.

HoursAfterEvent

Number of hours after the event when trading is allowed.

CalendarSource

Selects the calendar source.

CALENDAR_BUILTIN

Uses the built-in BOJ calendar dates included in the EA.

CALENDAR_LOCAL_CSV

Loads dates from a local CSV file.

CALENDAR_ONLINE_CSV

Loads dates from an online CSV URL. In the Strategy Tester, WebRequest is not used, so the EA falls back to local/built-in data.

CALENDAR_MANUAL

Uses manually entered dates from the input settings.

LocalCalendarFileName

Name of the local calendar CSV file. Default: ROI_Dates.csv

CalendarURL

• URL for online CSV loading. The URL must be allowed in MetaTrader 5: Tools -> Options -> Expert Advisors -> Allow WebRequest for listed URL.
• ManualEventDateTime
• Single manual event date for quick testing.
• ManualEventDateTimes
• Multiple manual event dates separated by semicolons.

Example:

2027.01.22 05:00;2027.03.19 05:00;2027.04.28 05:00;2027.06.17 05:00

HOW TO ADD BOJ DATES AFTER 2026

Option 1: Manual input directly in EA settings

1. Open EA settings.

2. Set CalendarSource = CALENDAR_MANUAL.

3. In ManualEventDateTimes, paste future dates separated by semicolons.

4. Use this format:

   yyyy.mm.dd hh:mi

5. Example:

   2027.01.22 05:00;2027.03.19 05:00;2027.04.28 05:00;2027.06.17 05:00

This is the easiest method for users who do not want to work with files.

Option 2: Local CSV file

1. Create a text file named ROI_Dates.csv.

2. Put it into the MetaTrader 5 common/files or terminal files folder used by the EA.

3. Add one event per line.

4. Use this format:

   yyyy.mm.dd hh:mi;Bank of Japan Interest Rate Decision

5. Example:

   2027.01.22 05:00;Bank of Japan Interest Rate Decision

   2027.03.19 05:00;Bank of Japan Interest Rate Decision

   2027.04.28 05:00;Bank of Japan Interest Rate Decision

6. In EA settings, set CalendarSource = CALENDAR_LOCAL_CSV.

7. Set LocalCalendarFileName = ROI_Dates.csv.

Option 3: Online CSV URL

1. Prepare a public CSV file with the same format.

2. Put the URL in CalendarURL.

3. Set CalendarSource = CALENDAR_ONLINE_CSV.

4. In MetaTrader 5, open Tools -> Options -> Expert Advisors.

5. Enable Allow WebRequest for listed URL.

6. Add the domain/URL.

Note: Online loading is intended for live terminal use. In the Strategy Tester, the EA uses local or built-in fallback data.
