We've been using the OTC desk at Paybis for our large trades for about six months, and it's been excellent for our needs. Their corporate desk provides personalized service with dedicated account management, which makes coordinating large transactions much smoother. The pricing is competitive, and more importantly, they're able to source liquidity without moving the market. The settlement process is secure and efficient, which is crucial when dealing with significant amounts. Their corporate services page details how they handle institutional-sized transactions differently from their retail platform.
