Market validation returns OnInit code 1, but report contains no EA diagnostic output

[Kasimu Ijelu]

Hello everyone,

I’m investigating an initialization failure during automatic Market validation of my MT5 Expert Advisor, The 500 Calabash EA, version 1.65.

test on EURUSD,H1 (hedging)

 tester stopped because OnInit returns non-zero code 1

 disconnected

there are no trading operations

The validation ran on 11 November 2026, from 09:56:50 to 11:27:26, as displayed in the report.

The submitted build includes Print /`PrintFormat` diagnostics intended to identify the first rejecting initialization check and its associated values. None of that output appears in the downloadable report.

What we have established:

• An earlier V1.64 submission reported “incorrect input parameters.”
• We corrected startup error classification to distinguish invalid inputs from other initialization failures, preserving the safety checks.
• The latest submission returns INIT_FAILED (1 ), but the rejecting check remains unknown.
• Separate local startup-diagnostic runs completed successfully on EURUSD/H1 with a hedging demo account. These were diagnostic builds, so I am not treating them as proof that the submitted production build must pass.
• “No trading operations” follows the initialization abort; it does not yet establish a separate trading issue.

Is there a supported way to retrieve the EA’s initialization diagnostic output or the detailed agent Journal from automatic Market validation?

If that output is unavailable, what diagnostic approach is recommended for identifying the exact failing OnInit() branch in the validation environment?

I want to correct the underlying problem while preserving safety guards—not force INIT_SUCCEEDED , bypass checks or add trades solely to satisfy validation.

Thank you for any guidance.
