Institutional ETF tape

Bid

Bid. IBIT and FBTC both creating (+433.0m, headline). Five-day +6m. ETH confirms.

Need a third green day and a 5-day sum at or above zero.

After hours. Settled print is the read. Next event scan in ~5 min — alerts fire on a sudden spot or premium move.

What the tape means

  • SettledRead

    The bid is aligned

    Both IBIT and FBTC created shares. Dips are more likely to be absorbed. Keep watching FBTC — it usually turns first when the bid fades.

  • SettledRead

    The week is still net buying

    The 5-day sum (+6m) is the regime number. One session cannot overwrite it. Direction for the next 1–5 days follows this sum, not the latest headline print.

  • SettledRead

    Ether confirms the Bitcoin bid

    ETHA/FETH are also creating (+143.7m). That is the cleaner risk-on tell.

  • SettledWatch

    Headline-sized print

    +433.0m is large enough to move the tape. Still wait for IBIT/FBTC agreement before acting.

  • LiveWatch

    IBIT is trading rich — create pressure

    IBIT implied premium is +5.36%. Authorized participants are incentivized to create shares and buy coin. This is live pressure, not a settled flow.

  • LiveWatch

    FBTC is trading rich — create pressure

    FBTC implied premium is +5.29%. Authorized participants are incentivized to create shares and buy coin. This is live pressure, not a settled flow.
