P2 Badge Validate round freshness before using Chainlink answer

getLatestPrice() ignores the metadata returned by latestRoundData(), so checkSignal() can make LONG/SHORT decisions from stale or incomplete rounds when the feed is delayed or recovering. In those scenarios the contract returns a seemingly valid signal from outdated data, which can corrupt downstream strategy logic; add round-validity checks (for example updatedAt != 0 and answeredInRound >= roundId, plus an optional staleness window) before accepting price.

Useful? React with 👍 / 👎.

return price;
}

// Apply to your oracle: Trigger action if price > threshold
function checkSignal() external view returns (string memory) {
int price = getLatestPrice();
// Integrate your off-chain signal logic here (or via custom oracle)
return price > 3000 * 10**8 ? "LONG" : "SHORT";
}
}
