MT5 price feed problems: diagnose data before it reaches the platform.
Stale quotes, missing symbols, abnormal spreads and inconsistent sessions can originate in upstream feeds, aggregation, symbol mapping, permissions or distribution into MetaTrader. A structured diagnostic path helps isolate the failing layer.
Validate the source
Check source timestamps, session status, instrument availability and failover state before assuming the trading platform is responsible.
Validate transformations
Review symbol aliases, decimal precision, contract settings, trading sessions and aggregation logic for instruments showing inconsistent behaviour.
Add observability
Monitor source freshness, quote gaps, spread ranges, failover events and downstream delivery so data issues can be detected before clients report them.
