Turnover Ratio.
Daily trading volume as a percentage of market cap. Thin tape, normal, or climax — at a glance.More than 10% of market cap traded today. Tops and bottoms both can come on climax volume — pair with a directional indicator (Mayer, Z-Score) to read which side it's capping.
Sub-2% turnover means moves are unreliable — small flows move price disproportionately. Wait for liquidity to thicken before sizing.
Below 2% the tape is thin — moves are driven by a handful of orders and reversals are common. Above 10% the tape is climactic — either panic distribution or news-driven euphoria, and either can mark a local turning point.
Smaller assets typically run hotter simply because they're smaller. Their natural turnover band is often 5–20% rather than 2–10%. The threshold cells let you re-calibrate per asset.
The ratio line on the chart is shaded magenta in proportion to its distance from the midpoint, so unusual liquidity stands out visually before you read the number.
Backtest: long-only on cross of the lower threshold (re-entering thin-tape periods), cash on cross of the upper (climax exit). Practical use is as a confirmation filter alongside a directional indicator, not as a standalone signal.
