How to choose
order flow software.

Depth of Market: a ladder of displayed buy and sell orders. A view of the order book does not automatically include order entry.

A stream of completed trades, usually showing time, price and size. It describes executions rather than orders still waiting.

The best displayed bid and offer, plus the trade information included by that feed. It does not show the deeper order book.

Displayed orders across multiple price levels. Coverage, number of levels and history depend on the venue and provider.

Market by Order: individual order records, rather than only aggregate size at each price. It requires suitable feed support and permissions.

The market-data permissions attached to your account: exchanges, instruments, depth and allowed devices or sessions.

Historical data loaded when you open a chart. Trade history, depth history and individual-order history are different products.

Playing historical data through the software. The result depends on the history recorded or supplied; tick replay does not guarantee full-depth replay.

The service that sends an order to a broker or exchange. Routing fees can be separate from commissions and data subscriptions.

An exchange-defined subscriber classification that affects data charges. A platform tier called “Pro” does not decide your exchange classification.

An annual or longer prepaid amount divided into months for comparison. It is not necessarily a monthly payment option.

A footprint shows executed volume within a bar at price levels. Delta compares classified buying and selling volume; feed and classification method matter.
