Real Capital serves as the final counterparty for Forex trading under both dealing desk and no dealing desk models, sourcing bid and ask prices from multiple liquidity providers. A variable mark-up is applied based on factors such as provider performance, network latency, liquidity depth, and execution quality. The dealing desk model may use fewer providers compared to the NDD option but includes backup providers as needed. Clients should consider their trading strategies when choosing between execution types, as quotes, prices, and spreads can vary between models.
