Wallet PnL: Realized & Unrealized Profit

Bitquery doesn't return a single "PnL" number — you compute it from a wallet's trade history plus the token's current price. This recipe shows the average-cost approach that most trackers use. It works on every chain the Trades API covers, including the Robinhood chain.

1. Pull the wallet's trades

Open the Bitquery IDE and run a Trades query filtered to the wallet, ordered by time. This returns each buy/sell with amount, price, and side — the raw material for PnL.

{
  Trading {
    Trades(
      where: { Trade: { Account: { Address: { is: "<wallet>" } } } }
      orderBy: { ascending: Block_Time }
      limit: { count: 10000 }
    ) {
      Block { Time }
      Trade {
        Side { Type }
        Amount
        Price
        Currency { Symbol Address }
      }
    }
  }
}

The Side.Type (buy/sell), Amount, and Price on each row are what you fold into a running position. Note the Trades API retention window — for deep history beyond it, use a cloud/S3 export.

2. Fold trades into a position (average cost)

For each token, walk trades in time order:

• Buy: increase quantity; increase cost basis by amount × price.
• Sell: realized PnL += amount × (sell price − average cost); reduce quantity and cost basis proportionally.
• Average cost = running cost basis ÷ running quantity.

# trades: list of {side, amount, price} in time order, per token
qty = 0.0
cost = 0.0        # total cost basis of the open position
realized = 0.0
for t in trades:
    if t["side"] == "buy":
        qty += t["amount"]
        cost += t["amount"] * t["price"]
    else:  # sell
        avg = cost / qty if qty else 0.0
        realized += t["amount"] * (t["price"] - avg)
        cost -= t["amount"] * avg
        qty -= t["amount"]

avg_cost = cost / qty if qty else 0.0
# unrealized needs the current price (see step 3)

3. Add unrealized PnL

Fetch the token's current price from the Crypto Price API, then:

unrealized = open_quantity × (current_price − average_cost)
total_pnl  = realized + unrealized

Caveats

• Price source matters. Use a consistent price feed (the same one you'd display) — the token-level price index is MEV/outlier-filtered; see which price to use.
• Fees & gas aren't included above — subtract them if you need net PnL.
• Method choice (average cost vs FIFO) changes realized PnL; pick one and be consistent.

Frequently Asked Questions

Does Bitquery return wallet PnL directly?

No — you compute PnL from the wallet's trade history (Trades API) plus the token's current price. This page shows the average-cost method.

How far back can I compute PnL?

As far back as the Trades API retains individual trades (a rolling window); for older history use a cloud/S3 export of trades. See the coverage matrix.

Can I compute PnL on the Robinhood chain?

Yes. The same trade-history approach works on every chain the Trades API covers, including Robinhood.
