Native MT5 Bars CSV export — OHLC decimal and timestamp semantics

New comment
 

Hello,

I am conducting private local research/backtesting using the native MetaTrader 5 workflow:

Symbols → Bars → Request → Export Bars / CSV

I would like to clarify the technical semantics of this native GUI export, not a custom MQL5 exporter.

Could you please confirm, or point me to official MetaQuotes documentation covering:

  1. The source fields/representation used for OHLC values in the native Bars CSV export.
  2. The meaning of the exported decimal values, including decimal separator/locale behavior, precision, and any rounding or truncation behavior.
  3. The price basis and construction semantics of OTC bars used by this exporter.
  4. The meaning of timestamps written by the native Bars CSV exporter, including the applicable time domain/timezone.
  5. Whether these rules depend on the terminal build/version.
  6. If the exported Spread field is relevant, its unit and aggregation semantics.

Please distinguish native GUI Bars-export behavior from custom MQL5 scripts or APIs.

No raw market data or account credentials are being provided.

Thank you.
