Map EURUSD to the exact OANDA instrument
Your TradeLocker provider may name a forex pair EURUSD or add a prefix or suffix. OANDA’s API uses EUR_USD for this pair. Map the exact sender symbol to the instrument shown on the receiving account. Naming differences should not send the trade to a different market.
Choose instruments from the connected OANDA account and keep your symbol filters aligned with that mapping. Instrument availability belongs to the account; a symbol mapping cannot add a market. OANDA’s instrument specifications also define quantity precision and minimum trade size.
