What's Difference Between DD and Market Maker Stock Account in Stocks?

DD Stock Account vs Market Maker Stock Account

DD Stock Accounts

DD stands for dealing desk, these DD account stocks brokers have a dealing-desk where they can match 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 and the broker can requote a stocks trader's order if the stocks price of the stocks market changes quickly enough before the broker's dealing desk places the trading order online or before they match the order in the online interbank stocks market.

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

MM Accounts

Market Maker Stock Accounts are stocks broker accounts where Market Maker stocks brokers have a dealing desk where they can match trading orders in house without going to the online inter bank stocks market.

Stocks orders can also be executed against their traders - meaning the broker can take the opposite side of a traders open trades.

This stocks broker can make the decision to either execute a stocks order that's the opposite of a stocks trader's order thus if the trader makes a loss the broker makes a profit, & if stocks trader makes a profit the broker makes a loss.
