Based on the Volume Delta [Aggregated Cumulative] chart for BTCUSDT (15-minute interval), here is the concise breakdown of order flow by size over the last few days:
Whale vs. Retail Order Flow
The Mega Whales ($1M to $10M tier): Aggressively Buying. This tier (purple line) is in a massive, steep uptrend, sitting at a dominant 1.83B. Large institutions or whales are aggressively absorbing and accumulating BTC.
The Rest of the Market (All other tiers): Selling / Net Short. * Retail & Small Whales ($10k to $1M tiers): Heavily net-short, led by the $10k–100k tier (yellow line) at -393.36M and the $100k–1M tier (pink line) at -235.29M.
Micro-Retail ($0 to $100): Slightly positive at 30.653M, but statistically negligible compared to the larger cohorts.

The Takeaway
There is a massive polarization in the market. Retail and mid-sized traders are heavily selling or shorting into this price action, while mega-whales ($1M–$10M) are completely dominating the order book by buying up all the sell pressure. This heavy whale accumulation against retail distribution typically hints at strong under-the-hood structural support for price.
