Each bet is entered by hand from a U.S. brokerage's options time and sales: every print's size, price, exchange and the quote at that moment. The tape does not say who started an order, so the side is a read. The page measures where the order filled within its quote and labels the read as likely, a lean or unclear, with the other read beside it.
A roll closes one position and opens another; only the opening legs are the bet going forward. Values, deltas and the payoff use Black-Scholes on each leg's own implied volatility. Fund prices are translated to the index as a one-day multiple, an approximation over weeks. Open bets are marked to market after each close from the options' closing prices until they expire.
Choosing which trades to log is itself a selection, so no logged bet is removed. Nothing here is a recommendation to trade.
