Forex Rates

This page covers metadata refresh jobs handled by fetch.js:

• Forex rates (fx_rates)
• Symbol information (symbol_info)

Both jobs can be run separately or together.

Downloads the latest Forex rates to ./res/fx-rates.json.

node ./bin/fetch.js --fx-rates true

INI equivalent:

fx_rates = true

Recommended use:

• Run once per day or more frequently.
• Run before generation or backtesting sessions.

Downloads symbols metadata file ./res/<server>.json.

node ./bin/fetch.js --server Premium --symbol-info true

INI equivalent:

server = Premium
symbol_info = true

Recommended use:

• Usually once per day.
• Also run after changing server.

node ./bin/fetch.js --server MetaQuotes --fx-rates true --symbol-info true

This is the preferred metadata refresh command before large fetch or generation sessions.

• If symbol info file is missing, data fetch cannot continue. Run with –symbol-info true first.
• If using a different server, fetch symbol info for that server so ./res/<server>.json is available.
• Use –silent true for automation scripts to reduce console output.

• Fetcher (fetch.js)
