Trends (daily, 34d window)
Fee change effectiveness (hourly)
Competitor-normalized before/after at the hour level. The change hour is excluded; "before" is the 24 closed hours prior, each "after" window the first 6/24/72/168 closed hours since (bounded by the next change). Verdict weighs Topaz fees/hr and volume share and competitor flow — a fee that lifts revenue but bleeds routing share is not "working". Hourly data refreshes with the daily collect (~02:15 UTC), so a change from the last ~24h shows pending until the next run brings in its post-change hours.
no pre-change Topaz volume to compare against

Fee change impact
On-chain fee changes on this pair's Topaz pool(s), with volume & fee generation before vs after each change. Each side spans all days until the adjacent change; rates are per active day (the two sides usually differ in length). Marked on the charts above. Values are raw module units (pips, ÷100 = bps; scaling is the raw uint64 K).
