If you carry-out transactions over USD $50,000, strive for an individual approach and want to minimise your risks, then OTC trading is the most optimal solution for you. This is the most convenient way of carrying-out large over-the-counter transactions between traders, which avoids price slippage when conducting transactions in order books (while a client buys limit orders in whole blocks, the price can change dramatically) and other also avoids difficulties with the execution of transactions on different exchanges.
