their volume are very high compare to OI,

5b daily volume on 100m OI is quite high, so we need to filter those farmers as fees are also very low, and they can easily earn 75% fees back by depositing in the LP pools, so that makes farming very cheap

@treeoflife2 I would like to work on this. Starting on this now.

@treeoflife2 PR ready with fee-rate based wash trading filter.

Detection: compare daily fees/volume ratio. Normal trading runs
0.010-0.012%. Wash trading days (May 20: $5.25B vol, 0 OI) show
0.0058% i.e half the normal rate.

Fix: if fee_rate < 0.008%, cap volume = fees / 0.008%

• May 20: $5.25B → $3.78B ✅
• Normal days: unchanged ✅

Uses both volumeRecordDailies and feesRecordDailies from the
official subgraph.
