Rebuilt every trading night.\n OPTO bid-ask spread and liquidity\n As of Nov 12, 2026, OPTO is too new to score: ETFIQ reads 0 of its 6 trading measures.\n IQ Liquidity Score\n Too new to score, 0 of 6 measured.\n A fixed 0 to 100 scale of trading conditions, the same anchors for every fund; 100 is the easiest to trade. It measures how cheaply and reliably the fund can be bought and sold, not whether to own it. How the score is built \n Cost to trade Not measured: the issuer's 30-day median spread is not read for this fund Capacity Not measured: no book of its holdings is read Price fidelity Not measured: no closing premium is held for this fund Primary market Not measured: it first traded on 2026-10-09, and no N-CEN ETF row for series S000104948 is in the quarters read (2024q4 to 2026q3) Bad-day behaviour Not measured: no daily closing premium is held for this fund Depth Not measured: needs trade and quote data (Phase 2) \n Capacity\n Not measured: no book of its holdings is read.\n How to trade OPTO\n When ETF spreads are usually widest in the first minutes after the open and the last minutes before the close. ETFIQ measures this fund\u2019s own day once it has trade data. Coming with trade data\n Spread through the day, buyers against sellers, an estimate of retail flow, large trades and the closing auction\u2019s share, each once ETFIQ has trade and quote data.\n Questions people ask\n Who is the LMM for OPTO?
