Trading style, from the data
Computed from all of the trades. These describe what the record shows; the record contains no information about the trader's intentions, so anything about motives is inference, not the trader's own rule.
What stands out
- High win rate, small winners. 62.3% of trades are profitable, but the average win is only 0.1× the average loss; a few large losses can undo many small gains.
- Losers are held longer than winners (median 17.5 h vs 2.9 h). In the data this looks like a tendency to sit with losing positions.
- Gains are concentrated: the best 10 trades account for 69% of all profit from winning trades.
- Short trades netted +$83.3K; long trades −$71.2M.
- Every holding-time range lost money overall; the smallest loss is under 1 hour (−$51.9K).
- The weakest is over 7 days (−$51.6M).
- HYPE is the most traded market (35% of trades), netting −$4.77M.

About the data
Several independent records merged and de-duplicated, then rebuilt fill by fill into positions.
From 2025-06-25 to 2025-10-02 only XPL, PUMP, BTC, ASTER, YZY and WLFI are included: ETH and HYPE fills in that period are incomplete and cannot be rebuilt reliably. From 2025-10-02 on, all markets are complete.
