I went through the documentation of Chainlink data feeds and saw we can get the latest price using
latestRoundData() function from
The documentation states the price update happens in two threshold, 'Deviation' and 'Heartbeat'. So the deviation for 'ETH/USD' is 0.5% and 1 hour heartbeat time.
But I see Pancakeswap.finance's prediction game uses Chainlink oracle to get latest price of 'BNB/USD' in real-time. But the deviation is not as near as 1% (as mentioned in https://docs.chain.link/docs/binance-smart-chain-addresses/) and it updates price in real-time even less than a minute.
May I know how to update price in real-time?
do we use keepers that keep a watch every second? or is using 'fluxmonitor' (as mentioned here Timed Chainlink oracle call) a good solution?
or is there a way to get price every time there is a price change (even in cents)?
