Map symbols for the selected MatchTrader account
Use the exact instrument name from each side of the connection. A TradeLocker symbol such as EURUSD can map to EURUSD.m if that is how the corresponding instrument appears on your MatchTrader receiver. Include the receiving account’s suffix and confirm the underlying market.
Your broker or prop firm controls which instruments are available in its MatchTrader environment. Use that account’s contract details when choosing the mapping and size. When another receiver uses a different provider, configure its mapping separately.
