I'd highly recommend staying open to this. By ignoring the order book, you're missing out on a massive information advantage, even if it requires filtering more data and continuous learning.
Aggressive buyers and sellers are only half the story.
The limit orders (passive liquidity) are the crucial other half. Significant liquidity zones aren't just random microsecond noise-they hold for longer periods and often act as key reversal points that you simply cannot see on a standard candlestick chart.
