Taker Buy Sell Ratio measures the proportion of aggressive buying volume relative to aggressive selling volume in perpetual swap markets, where takers are participants who execute against existing orders and therefore represent the most immediate expression of directional market intent.
When the ratio is above 1, buy-side aggression is dominant - more volume is being initiated by buyers lifting offers than sellers hitting bids, reflecting bullish sentiment and active demand in the derivatives market. When the ratio is below 1, sell-side aggression dominates, indicating bearish sentiment and more participants actively pushing price lower through market orders. Because takers drive price discovery in the short term, sustained readings above or below 1 can confirm or challenge prevailing price trends rather than simply reflect them.
Monitoring the Taker Buy Sell Ratio alongside funding rates and open interest provides a more complete picture of derivatives market sentiment - distinguishing between markets where bullish or bearish positioning is being passively held versus actively executed, which carries meaningfully different implications for near-term price direction.
