Market Selection Process
The market selection process consists of a systematized approach for evaluating markets to serve as an input for the calculation of the BLOCKSIZE CONNECT price data feeds. It generates a list of potential cryptocurrency exchanges that are subsequently reviewed by the BLOCKSIZE Data Committee. The markets selection framework evaluates exchanges based on the following criteria:
Technology: An assessment is done into whether or not the technical infrastructure of the market’s exchange provides sufficient availability and reliability for data collection. Additionally, it is evaluated whether the exchange offers a REST or RPC API and/or a WebSocket feed that fits our requirements for data collection. Lastly, the performance of the API in terms of reliability and latency is checked.
Legal and Compliance: The BLOCKSIZE operations team does an assessment on the compliance and legality of the market’s exchange in accordance with the laws and regulation it’s jurisdiction. The market’s legal risk exposure is then evaluated. Transparency of the market’s business operation is assessed based on whether or not the market’s exchange has publicly disclosed trading policies, uses market surveillance tools, and enforces KYC and AML requirements.
Data Availability: The market exchange’s data availability is checked to determine which crypto assets are listed and whether it is sufficient to meet client needs.
Price: The BLOCKSIZE Data Committee evaluates the quality of the market’s price data for significant deviations from other peers.
Volume: For every asset that we list, we check the trading volume of a given asset pair. If it is determined that the trading activity is not sufficient enough to represent a reliable price reflective of the whole market, then it is rejected.
