What is GBP/JPY called on Prometheus?
GBP/JPY is called GBPJPY on Prometheus. Use that exact string in SymbolSelect() or iCustom() — MetaTrader symbol names are case-sensitive and will not resolve a close match.
Broker symbol names diverge because each one configures its own market watch. The same instrument can appear as a plain code, with a letter suffix for an account type, or under a legacy vendor name. The code above was read from Prometheus's live server, not copied from marketing material.
What is the minimum lot size for GBP/JPY on Prometheus?
The minimum trade size for GBP/JPY on Prometheus is 0.01 lots, and size increases in steps of 0.01 lots — 1,000 units of the underlying at minimum.
An EA that sends a volume below this, or one that is not a whole multiple of the lot step, is rejected with error 131 (invalid trade volume) — normalise your lot size against both numbers before calling OrderSend.
