The Price Feed Oracle works to provide the latest or past market price of specific tokens, aggregated from (>=1) trusted external entities (hereafter referred to as oracles). Token price aggregation happens in rounds, triggered by oracles. For a round of aggregation, multiple oracles submit their 'price' answers and the final determined answer is the median of all submissions. The 'price' answer for the round isn't finalized/accepted until the round has received a certain 'min no of answer submissions' from separate oracles. While the round moves between having min < submissions < max, the computed answer can vary depending on the data received up till that point. And after the 'max no of submissions on the round' the 'price' answer is finalized and fixed. If a round does not receive 'min no of answer submissions', the round can be superseded after a timeout period. The Terms used here and throughout - 'base' refers to the crypto asset/token and 'quote' refers to the asset (or fiat currency) to use as a reference for the price.
