Back when I traded a small alt, these metrics kept me honest:

- Wash/self-trading: a large chunk of matched trades between accounts that share ownership; same timestamp, same size.
- Unexplained volume spikes: sudden volume surge without news or liquidity, price barely moves then snaps back.
- High order-cancellation rate: lots of orders placed and canceled before any fill.
- Trades at the top of the book: frequent prints at the bid/ask with shallow depth and little price improvement.
- Flat net exposure: after a cluster of trades, the net position barely changes.

If you spot these, treat it as suspicious and dig into counterparties, order history, and how liquidity is being shown.

I spotted wash trading when I saw rapid mirrored trades between the same two wallets, odd price prints, and 90% of volume at odd hours.
