What's the Difference Between NDD and DD Stock Account in Stocks?

NDD Stock Account vs DD Stock Account

NDD Stock Accounts

NDD stand for Non-Dealing Desk stocks execution of orders, these NDD Stock Account stock trading brokers do not have a dealing desk - this makes this type of trade execution model to have less trading restrictions compared to Dealing Desk Execution Model.

NDD Execution means that trades from the traders account will be executed direct to online inter-bank exchange stock market. Orders will be matched with other orders in the inter-bank stocks market using the broker Non Dealing Desk order execution model.

DD Stock Accounts

DD stands for dealing-desk, these DD account stocks brokers have a dealing desk where they can match trading orders and execute stocks order in the online interbank stocks market.

The stocks trader trading with a DD account will get a lot of requotes.

Dealing Desks will issue stocks traders with a lot of order requotes, meaning stocks prices of orders are not realtime & the broker can requote a stocks trader's order if the stocks price of the stocks market changes quick enough before the broker's dealing desk places the order online or before they match the trade order in online inter-bank stocks market.

Dealing Desk accounts therefore means that order execution of stocks orders is not instant and therefore this execution model might mean that orders executed using a DD Stock Account are not executed as quickly as when compared to an ECN account or an STP trading account.
