The phrase refers to obtaining software, typically at no cost, designed to analyze the stream of buy and sell orders in financial markets. A hypothetical scenario involves a trader seeking tools to visualize the number of buy and sell orders at different price levels to predict short-term price movements. These applications aim to provide an enhanced understanding of market dynamics.
Acquiring such systems can offer benefits like improved trading decisions and a potentially deeper awareness of market sentiment. Historically, access to such analytical capabilities was primarily limited to institutional investors. The availability of cost-free options democratizes this access, enabling individual traders to leverage similar techniques. However, users must exercise caution, verifying the provenance and functionality of any complimentary offerings to avoid malware or unreliable data.
