Single-symbol EA (XAUUSD only) fails Market validation on EURUSD - "no trading operations" - how did others get this approved?

[Nicolas Hernando Roncancio Burgos]

Hi everyone,

I'm trying to publish an EA that is intentionally designed and calibrated exclusively for XAUUSD. It's not a generic multi-symbol robot restricted by a code lock - the entry logic itself is calibrated to gold's price scale (it measures price movement in whole-dollar ranges), so it genuinely doesn't generate valid entry signals on other symbols.

Automatic validation results:

- XAUUSD,D1: works correctly. 8 completed trades, full recovery sequence executing as designed, zero errors.

- EURUSD,H1: "there are no trading operations" - this is expected, not a bug, given the reason above.

Total errors count: 7. Validation state: "Validation completed with errors."

I've already read "The checks a trading robot must pass before publication in the Market" article, and I understand the general guidance that restrictions should be described rather than hard-coded. I removed all hard blocks from the EA (no INIT_FAILED, no forced restriction) - it simply doesn't find a valid setup outside gold's price scale, which is normal behavior for the strategy.

I've also opened a Service Desk ticket requesting manual review, currently waiting on a response.

Has anyone here successfully published a genuinely single-symbol EA (not artificially blocked, just strategically calibrated to one instrument) despite this validation result? What ended up working for you - manual review, a specific code adjustment, or something else? Any concrete guidance would be really appreciated.

Thanks in advance.

You cannot force validator to use only XAUUSD.

According to MetaQuotes rules the automatic validation process is designed to ensure a product is robust across different environments (any symbol/timeframe):

"Products cannot apply restrictions. All limitations should be marked as recommendations"
