Generic Steps

These are the built-in steps that come with workflows.

Step: Generic\RunEA

Opens a chart, runs an EA and waits for it to finish. Closes the chart when done.

Structure

- name: "RunEA"
  module: "Generic"
  with:
    fixed:
      name: "Experts\\Path\\MyEA.ex5"
      symbol: _Symbol
      timeframe: _Period
      run_flags: "DLL|AutoTrading"
      ms_sincronizacion: 500
      timeout_segundos: 300
    ea_params:
      - ParameterName: ["TYPE", "value"]
      - .
      - .

fixed Parameters

Parameter	Required	Description
name	Yes	EA path relative to MQL5\ (must always include Experts\\ — the EA must be located there)
symbol	No	Chart symbol. _Symbol uses the current one
timeframe	No	Timeframe. _Period uses the current one, based on ENUM_TIMEFRAMES. Note: PERIOD_CURRENT is invalid, use _Period instead
run_flags	No	Permissions for the EA to run. Two permissions exist: "DLL" enables DLL calls and "AutoTrading" enables auto trading. These can be combined using the pipe separator
ms_sincronizacion	No	Wait time in ms before launching the EA. Default: 1000
timeout_segundos	Yes	Maximum execution seconds. Must be greater than 0

ea_params Parameters

List of EA inputs. The name is optional — only the order matters.
Each parameter has the following structure:

- Name: ["TYPE",  value]

• TYPE: from the ENUM_DATATYPE enumeration
• value: String\Number\Double

ea_params:
  - InpNum: ["TYPE_UINT", "${{internal.number}}"]
  - InpTexto: ["TYPE_STRING", "hello"]

Step: Generic\PowerShellCommand

Launches a PowerShell command as an external process and waits for it to finish.

Structure

- name: "PowerShellCommand"
  module: "Generic"
  with:
    run: "Write-Output 'hello'"
    timeout_segundos: 300

Parameters

Parameter	Required	Description
run	Yes	PowerShell command to execute. Cannot be empty
timeout_segundos	No	Maximum wait seconds. Default: 300

Notes

The command is executed internally as:

powershell -NoProfile -NonInteractive -Command "..."

If the process exceeds the timeout it is killed automatically.
