Every level in the brief is computed by us from public exchange APIs that anyone can query. No paid vendors, no numbers copied from other channels.
Source: Deribit public API. Open interest by strike for every BTC and ETH option, implied volatility, greeks and the DVOL index. Our archive snapshots the whole chain every hour since 10 March 2026, so every Thursday number can be checked against its own snapshot.
Source: Bybit public market API, option tickers with open interest by strike. Used for the second max pain next to Deribit.
Max pain, the market maker corridor, the put and call walls and the gamma flip are computed from that open interest and greeks. The Friday result uses the official settlement.
Source: Deribit public API block trades, every 5 minutes. The legs of one block are grouped, and we only count blocks of $5M or more gross notional on BTC or $3M or more on ETH. Positions of every account in our Hyperliquid whale registry, about 220 today, are read about every 8 minutes.
Copied as posted. We leave the entry price out on this page.
The free channels show the same whale feed in public: @whalewatch_free in English and @whalewatch_gratis in Spanish get the 2 largest alerts of each day, 90 minutes late.
The strike where option buyers as a group would lose the most at settlement. It is a reference level, not a promise of where price ends. Our record shows how often it was hit.
No. It is a map of where positioning sits before expiry. Our own record shows the corridor misses about one time in five.
Because it beat our corridor on the same width. You should know that before you pay.
