Tips for Setting Optimal Rates​

Research Current Market Rates​

  • Check the Liquidity tab to see what other providers offer
  • Look at external exchanges for reference FX rates

Consider Spread and Competitiveness​

  • Lower spreads (0.5–1%) = faster sales, lower margin
  • Higher spreads (1–3%) = higher margin, slower sales
  • Balance depends on your strategy

Monitor Performance​

After updating rates:

  • Monitor how quickly your orders are filled
  • If they're slow to fill → lower your spread
  • If they're filling instantly → raise your spread slightly

Currency-Specific Strategies​

  • Popular currencies like EUR may allow higher spreads
  • Rare currencies might require more competitive rates
  • Optimize for each currency independently
