Jane Street traders ask three questions before every trade: why the edge works, who loses, and whether data supports it. Volume Profile shows where the market has historically done business, letting you establish a bias before price action even starts.
Jane Street is one of the most profitable trading firms in the world, and before they take any trade, they answer 3 questions: Why does this edge work? Who is losing? And does the data confirm it? The Volume Profile answers all 3 questions before you even place a single trade. It shows you where the market actually did business, where the largest positions are built, and it's based entirely on transaction data. So the edge is confirmed before you ever enter. Here's how I use it every day. Before the session opens, I look at where price sits relative to the previous session's value area. Above it and holding, I lean long. Below it and rejecting, I lean short. One level before a single candle even prints.
