A trader profile

A trader profile is everything Ballista knows about one wallet, with each part labelled by where it came from and how old it is. Open one from any row on the Leaderboard, from the wallet lookup box, or by going to the address directly. The wider question this page exists to answer is Choosing a trader; the concept is Trader profiles.

​

The header

The address with a copy button, its rank if it has one, and two buttons: Backtest this wallet and Copy this trader. Both hand the address to the relevant form and seed nothing else — the run or the copy trade is still one you configure. A wallet the maintained universe no longer sees trading is badged rotated out.

​

The provenance line

Under the address, one line saying where the statistics below came from:

• Live statistics, read n ago — fetched from upstream at most fifteen seconds before the page was served.
• From the last refresh sweep, n ago — the live call did not answer, so these are the worker’s last maintained values.
• No statistics available for this wallet yet — the wallet is in the universe but has never been refreshed, so every stat below is blank rather than zero.

Hover or focus the line for the longer version. A wallet outside the maintained universe also says so, and has no rank. This distinction is on the page rather than flattened away because “as of fifteen seconds ago” and “as of an hour ago” are different claims about a number you are about to risk money on.

​

Recent activity

7d P&L, 30d P&L, 30d volume, Last active, and a 30-day cumulative P&L chart underneath. The two P&L tiles and the chart are realized P&L from Ballista’s own cached tape for this wallet, valued the way the backtester settles — positions still open are not in them. The other two tiles are what they say: traded volume over the last 30 days, and when the wallet last traded. The block sits above the lifetime one on purpose: it is the only part of a record you can still follow into a trade. A blank tile says which of three things is true, and only one of them is worth waiting through:

​

Lifetime

Eight tiles: Realized P&L (settled markets only), Unrealized P&L (open positions at their current mark), Total P&L, Volume, Win rate, Profit factor, Positions and Wins / losses. Where a figure cannot exist it says why rather than showing a zero — “no market has settled yet”, “no losses to divide by”.

​

Copyability

The block that answers whether a copy trade can actually follow this wallet, and the answer is mostly its taker share: the fraction of its volume that crossed the spread, weighted by notional rather than by fill count. The block reads out one of three bands — aggressive at 60% or more, mixed between, passive at 30% or less — with a sentence on what each means for a copy trade. What the bands imply, and how to weigh one against a wallet’s P&L, is in Choosing a trader. The percentage is always on screen beside the words. It is not a score, and nothing blends it with P&L or win rate into a grade — a blended number would hide exactly the disagreement you need to see: a spectacular P&L with a low taker share is not a wallet to copy.

​

Copy friction

Below the band, under a divider, Copy friction, last 30 days shows four tiles: Slip rate, Slip amount, Backtest copy P&L — your side, replayed as a taker — and Actual 30d P&L, the wallet’s own, so the two sit next to each other. A line underneath states the assumptions the replay used, and a wallet the engine has judged carries a badge beside the heading with a sentence explaining it. When it cannot be measured the block reads Copy friction not measured, shows a dash, and gives the reason — ending on the point that this is neither zero nor clean, but unmeasured. What these numbers mean, and how that verdict is reached, is in Choosing a trader.

​

When these figures appear

Everything in this section comes from the wallet’s trade tape. Board wallets are swept automatically, roughly daily, so the numbers arrive on their own. Running a backtest harvests this wallet’s tape immediately and is the way to stop waiting — the block offers a Backtest this wallet button when there is no tape at all. Opening this page deliberately does not start a harvest: a full tape is heavy, rate-limited work shared with live copy trading. There is a second, different blank: a tape exists but has nothing in it to weigh. That one says so plainly and does not send you after a backtest you have already paid for.

​

Execution profile

Four tiles from the cached tape, captioned with how many fills across how many markets and when the tape was synced:

• Median hold — share-weighted, over the closed lots in the tape
• VWAP entry — volume-weighted average buy price, in cents
• Hedged markets — the share of markets where more than one outcome was bought
• Last 20 markets — a wins / losses / flat record, with the P&L behind it

A blank tile here says either not measured yet (no tape yet — wait for the sweep, or run a backtest to harvest one now) or not in the cached tape (a tape exists, but this particular metric cannot be computed from it — a VWAP entry for a wallet that has only ever sold, for instance). Hover or focus for the full explanation. Two notes appear when they apply: that the fill budget cut the read short, so the tiles describe only the most recent fills; and that some sold shares had no matching buy inside the cached window, so the median hold describes only the recent part of the wallet’s behaviour.

​

Recent trades

The wallet’s last few fills — market, price, size, value, its own side, whether it was maker or taker, and how long ago. Capped at twenty rows, and labelled as the preview it is. The caption says where they came from. From the harvested tape means deduplicated rows out of our own cache. One live page means no tape is held for this wallet and this was fetched on the spot.

​

Not found

A well-formed address nobody has traded with says exactly that: a wallet appears here once it has made at least one trade. A malformed address is caught before the request is made.
