The field MatchAlgorithm seem to be used to convey what algorithm is used to match orders in a specific market segment. However, both price-time and price-internal-time fall under the same category (FIFO).
How can I tell that e.g. market X has price-time and market Y has price-internal-time?
Custom values in MatchAlgorithms such as “FIFO-price-time” vs “FIFO-price-internal-time”, or assume that “FIFO” means price-time and introduce something new for price-internal-time? Or is there another field?
