Where can I get order flow or foot print?

There are many ways to get them.

Third-party software: There are several third-party software providers that offer order flow and footprint charts, such as Sierra Chart, Bookmap, and Jigsaw Trading. These platforms typically require a separate subscription or purchase.

Broker-provided tools: Some brokers offer order flow and footprint charts as part of their trading platforms. Examples include Tradovate and Stage 5 Trading.

Custom development: Some traders develop their own order flow and footprint tools using programming languages such as Python or R. This option requires significant technical expertise but can offer greater flexibility and customization.

I would personally call order flow as market profile. Market Profile indicator can be used in TradingView.

Many trading platforms provide real-time order flow data, but it is important that we choose reputable platforms that ensure the provision of accurate and reliable information. Accurate data enhances market analysis, facilitates efficient trade execution, builds trust and credibility, and enables effective risk management.
