Trader Grades

Every trader gets one letter grade. It answers one question: should you pay attention to this wallet? Grades show up on the leaderboard, on every trader profile, and inside every whale trade object.

The scale

Grade	One-line meaning	On the leaderboard?
S	Elite. Years of evidence, outsized P&L, high win rate, real volume.	Yes
A	Strong. Consistently profitable, well-diversified across markets.	Yes
B	Above average. Solid recent track record, smaller sample.	Yes
C	Roughly breakeven. Not a clear signal.	No
D	Net losing across the sample.	No
F	Persistently losing. Often coin-flip or chasing resolved markets.	No

The leaderboard ranks only S, A, and B. Those are the wallets worth following.

What goes into the grade

The score is a composite (0-100) of five inputs:

Realized P&L: actual profit from closed positions, not unrealized markings.
Win rate: share of markets that resolved in their favor.
Volume: total traded size. More volume means more signal per trade.
Market count: distinct markets they have touched (diversification).
Recency: penalizes wallets that have not traded in a long time.

Score thresholds assign the letter. Only B or better makes the leaderboard.

Two real profiles, side by side

S-grade: deep history, sustained edge

{
  "object": "trader",
  "data": {
    "id": "trd_0x863134d00841b2e200492805a01e1e2f5defaa53",
    "username": "RepTrump",
    "grade": "S",
    "score": 97.94,
    "pnl": 7532409.67,
    "win_rate": 1.0,
    "markets_traded": 28,
    "strategy_type": "swing_trader",
    "best_category": "politics"
  }
}

Very high realized P&L, near-perfect win rate, a classifiable strategy, a clear category strength.

C-grade: noisy and small

{
  "object": "trader",
  "data": {
    "id": "trd_0xc111...",
    "username": null,
    "grade": "C",
    "score": 42.10,
    "pnl": 318.55,
    "win_rate": 0.5238,
    "markets_traded": 21,
    "strategy_type": null,
    "best_category": null
  }
}

P&L near breakeven, a coin-flip win rate, no detectable strategy. Visible in the API, but not on the leaderboard.

Using grades in the API

Filter whale trades by grade

Only see trades from A-grade or better:

curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \
  "https://api.0xinsider.com/api/v1/whale-trades?min_grade=A&limit=50"

min_grade accepts S, A, B. Setting min_grade=A returns S and A.

Filter the leaderboard by strategy

Pull only S/A/B-grade swing traders:

curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \
  "https://api.0xinsider.com/api/v1/leaderboard?strategy=swing_trader"

Some traders make the leaderboard but lack a classifiable strategy. Their strategy_type is null, so treat the field as nullable when filtering client-side.

Combine grade + category

What are A-grade or better crypto traders trading right now? (Each item carries its side in the response, so you can split buys from sells client-side.)

curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \
  "https://api.0xinsider.com/api/v1/whale-trades?min_grade=A&category=crypto&limit=50"

A note on null strategies

A leaderboard trader without a strategy classification just means we haven’t detected a stable pattern yet. They are still a graded trader. Don’t filter them out unless you actually need a labeled strategy.
