Smart contracts can’t see off-chain prices themselves. How are these prices brought on-chain?
Smart contracts on the blockchain can’t access internet data on their own. They need oracles to write external data on-chain—this is what’s commonly known as the “oracle problem.”
When I first got into crypto, I thought understanding candlestick charts was enough. Later, I realized that learning the rules was the real first lesson.
Size your positions according to your risk tolerance, and leave yourself plenty of room.
