Open Interest Participation

Start: 2026-10-25 18:00 UTC. End: 2026-10-25 22:00 UTC. OI uses these exact endpoints; volume includes completed minutes from start inclusive to end exclusive.

The end is the last completed UTC hour at least ten minutes old. Successful reads refresh on request after 120 seconds; failed reads retry after 30 seconds.

Positive values mean net OI expansion; negative values mean net contraction. Raw USD OI also changes with price. The starting-price-adjusted estimate removes the endpoint mark-price change. USDT quote notionals are shown as USD equivalents.

Raw delta = OI_end − OI_start. Raw ratio = 100 × (OI_end − OI_start) / sum(quote_vol). Starting-price-adjusted delta = OI_end × mark_start / mark_end − OI_start. Adjusted ratio = 100 × adjusted delta / sum(quote_vol).

Scroll the table horizontally for endpoint values and minute coverage. Contracts stay in a fixed order; unavailable observations have no numeric ratio.

Each row pairs stored OI snapshots and traded quote volume by the same market ID. Only Binance and Bybit BTCUSDT and ETHUSDT USDT linear perpetuals are included. No prices or volume are borrowed from another contract or venue, and no older snapshot substitutes for an exact endpoint.

Both exact anchors, finite nonnegative OI, positive finite marks, all 240 unique minute bars and positive total quote volume are required for either ratio. Missing, duplicate or off-minute bars make coverage incomplete. Missing or invalid data leave the ratios unavailable with a reason. Zero OI change with complete data is a valid zero.

This is a starting-price-adjusted estimate, not a precise base-unit participation ratio: the denominator is stored quote volume, not base-coin volume. Constant coin OI with only a mark-price change gives zero adjusted delta. Ratios are signed and are not clamped to 0–100%.

Net OI change does not count new traders, distinguish longs from shorts, prove that traded volume opened positions, or measure leverage. Offset openings and closings can leave OI unchanged despite substantial trading. Data comes from recorded exchange public feeds; complete stored minutes do not establish that every exchange trade was captured.
