ABOUT THE INDEX

Clear comparisons.
Visible evidence.

Order Flow Index helps traders compare order flow software, access requirements and the costs beyond the licence.

What the research covers

We review official product documentation, pricing pages, exchange-data tariffs and published performance information. Platform pages link to those sources and identify missing or conflicting information. This is documented research, not a claim that we have traded live on every platform.

How the ranking works

The default Browser & value profile puts software affordability and documented browser access first. The same formula applies to every platform; ties share a rank. It is a preference-based shortlist, not a universal best-platform verdict.

Unknown criteria retain an unresolved range in the total. We sort by documented points; a wide range signals missing evidence, not measured performance. Cost scores use the reference software plan, while setup budgets separately show data and connection assumptions.

Full scoring rules

Prices and performance need context

Monthly billing, annual prepayment, exchange fees and tax are separate. Plans do not contain identical features. Refresh settings, frame-rate claims and reports of lag do not establish an end-to-end speed winner.

Pricing research is dated 3 October 2026; performance research is dated 4 October. New comparisons were prepared on 5 October with selected source checks. We change evidence dates when the underlying evidence is reviewed.
