Data sources

No trader signs up and no result is self-reported. Every record on Meror is read from a source that is public by law or by design, and each source states how far behind the trade its publication runs.

Azuro (on-chain sportsbooks)

  • Public blockchain · Near real-time: typical delay 60 sec · Global · 877 traders
  • Attribution: Azuro protocol (documentation)
  • What a return measures: Returns are the wallet’s real, settled profit and loss on-chain: stake, odds and payout for every bet. The curve is cumulative profit over the money the wallet demonstrably keeps at risk (its open stakes and its own drawdowns), because a blockchain shows bets, not bankrolls.
  • Basis for use: Bets placed through the Azuro protocol are public blockchain transactions, read from Azuro’s public subgraph and gateway API. Wallets are pseudonymous; no account, key or agreement is needed to read them.

Hyperliquid (on-chain perps)

  • Public blockchain · Near real-time: typical delay 20 sec · Global · 26366 traders
  • Attribution: Hyperliquid (documentation)
  • What a return measures: Day, week, month and all-time returns are the venue’s own figures for this wallet. Fills carry exact prices, sizes and timestamps from chain state. The daily curve begins at first observation because no daily history is published. Positions are leveraged perpetuals; exposure can exceed account value.
  • Basis for use: On-chain public data served by Hyperliquid’s unauthenticated read API, which carries no robots restriction. Positions, fills and returns are public by the design of the settlement layer.

Polymarket (on-chain)

  • Public blockchain · Near real-time: typical delay 30 sec · Global · 84234 traders
  • Attribution: Polymarket (documentation)
  • What a return measures: Returns are the real profit and loss on the trader’s open event-contract positions, reported per position by Polymarket and settled on-chain. The daily curve begins at first observation because no daily history is published; lifetime trade counts and per-position P&L are exact.
  • Basis for use: On-chain public data served through Polymarket’s unauthenticated read API, which carries no robots restriction. Positions and profit are public by the design of the settlement layer, not by any individual permission.

Binance Copy Trading (lead traders)

  • Venue leaderboard · Near real-time: typical delay 30 sec · Global · 11942 traders
  • Attribution: Binance Futures Copy Trading (documentation)
  • What a return measures: Returns are Binance’s own daily ROI series for the lead portfolio, rescaled to its current margin balance. Positions carry the venue’s entry and mark prices; closed positions carry their realised result. Leverage is real and shown.
  • Basis for use: Lead traders on Binance Futures Copy Trading publish their portfolio, positions and history to the public by opting in as leads. Read through the same unauthenticated endpoints Binance’s own copy-trading pages use; no account or key.

Linked Brokerage Accounts

  • Venue or broker data · Real-time: typical delay 1 sec · US/CA · 2 traders
  • Attribution: Linked brokerage account (via SnapTrade) (documentation)
  • What a return measures: Returns are the change in value of the trader’s actual connected brokerage account, including cash, from the day they linked it. Nothing before that date exists in this record, because a brokerage connection cannot reconstruct a history it was not present for.
  • Basis for use: Read-only access granted by the account holder through a brokerage aggregator, with explicit, revocable consent to publish their performance on Meror.

SEC N-PORT Fund Holdings (live)

  • Regulatory filings · Public disclosure: typical delay 2 months · US · 149 traders
  • Attribution: SEC EDGAR, Form N-PORT (documentation)
  • What a return measures: Returns are the fund’s own monthly total returns as filed on Form N-PORT, so they include every holding, fees and cash. The book shown is the month-end portfolio from the latest filing, published about sixty days after the quarter; trades are the changes between consecutive filings and are dated to the period end, not the day they happened. Only listed US and Canadian stocks and ETFs in the book route to a brokerage.
  • Basis for use: Form N-PORT is a public SEC filing (17 CFR 270.30b1-9) read from EDGAR under the SEC’s fair-access policy. Holdings, net assets and monthly returns are the fund’s own sworn figures.

eToro (public profiles)

  • Public leaderboard · Delayed: typical delay 60 min · Global · 126701 traders
  • Attribution: eToro public profiles (documentation)
  • What a return measures: Returns are eToro’s own monthly gain figures compounded into a curve. Positions are the venue’s reported weights; closed positions carry the venue’s open and close prices and times. Dollar sizes are not published, so figures are in percent of the account.
  • Basis for use: eToro users who make their profile public (every Popular Investor, and any account others may copy) publish their portfolio, closed positions and gain history on eToro’s site for anyone to read without an account. Read through the same unauthenticated endpoints the site itself uses; no key, no login.

pump.fun (Solana memecoins)

  • Public blockchain · Near real-time: typical delay 60 sec · Global · 3907 traders
  • Attribution: pump.fun (documentation)
  • What a return measures: Day, week, month and all-time results are the venue’s own profit figures for the wallet, net of price moves and excluding deposits. The curve is rebuilt from those windows, so it is sparse until the wallet has been tracked for a while. Positions carry the venue’s cost basis and mark; exited coins carry the venue’s realised result. Memecoins are illiquid: paper fills assume 1.5% slippage plus the venue’s fee.
  • Basis for use: Solana wallets are public by design. Holdings, cost basis, results and fills are read from pump.fun’s own public, unauthenticated API (the same endpoints its site uses) and from the chain through a public RPC; no account or key. Kolscan’s public page is used only as a list of wallet addresses.

OKX Lead Traders

  • Exchange copy-trading board · Near real-time: typical delay 60 sec · Global · 105 traders
  • Attribution: OKX (documentation)
  • What a return measures: Win ratio, days as a lead trader, copier count and P&L are OKX’s own published figures. Open positions carry the venue’s mark and entry prices. The daily curve begins at first observation because OKX publishes no daily history.
  • Basis for use: OKX’s public copy-trading API, which the exchange publishes for lead traders who have opted in to being followed. OKX’s robots.txt places no restriction on /api/.

SEC 13F Filings (live)

  • Regulatory filings · Public disclosure: typical delay 45 days · US · 8859 traders
  • Attribution: SEC EDGAR (documentation)
  • What a return measures: Returns are the change in value of the manager’s disclosed long US equity holdings between consecutive 13F filings, priced at each filing. Form 13F excludes short positions, cash, bonds, non-US listings and most derivatives, so this measures the disclosed book, not the fund’s own reported return. Positions opened and closed inside a single quarter are never disclosed and cannot be included.
  • Basis for use: Public domain filings published by the U.S. Securities and Exchange Commission through EDGAR. Retrieved within the SEC fair-access rate limits with a declared User-Agent.

Collective2 Strategy Marketplace

  • Audited strategy feed · Near real-time: typical delay 5 sec · US · 743 traders
  • Attribution: Collective2 (documentation)
  • What a return measures: Returns come from the strategy’s Collective2 equity curve (after costs). Collective2 model accounts trade a hypothetical portfolio; results are audited by Collective2, not by Meror.
  • Basis for use: Licensed API access to Collective2 (API4). Strategy records (equity curves and closed trades) are published by Collective2 for every live strategy; live positions are available to subscribers of a strategy.

SEC Form 4 Insider Filings (live)

  • Regulatory filings · Public disclosure: typical delay 2 days · US · 49 traders
  • Attribution: SEC EDGAR (documentation)
  • What a return measures: Form 4 reports an insider’s transactions in their own company’s stock, not a portfolio. Holdings shown are inferred from the running share counts in their filings and valued at the most recent price implied by institutional filings. Only open-market purchases and sales are treated as trading decisions; grants, option exercises and shares withheld for tax are compensation events and are labelled as such.
  • Basis for use: Public domain filings published by the U.S. Securities and Exchange Commission through EDGAR. Retrieved within the SEC fair-access rate limits with a declared User-Agent.

U.S. House Disclosures (Clerk)

  • Regulatory filings · Public disclosure: typical delay 30 days · US · 62 traders
  • Attribution: Clerk of the U.S. House of Representatives (documentation)
  • What a return measures: Reports give trades in dollar ranges, not holdings or prices. Positions and weights are estimates from range midpoints. Returns are the change in value of the disclosed transactions between filings, marked at the filing-derived prices with deposits excluded; the curve moves at the filing cadence and lags the member’s actual book.
  • Basis for use: Periodic Transaction Reports filed under the STOCK Act and published by the Clerk of the House of Representatives. They are public records read from the Clerk’s own site; nothing is licensed or scraped from a third party.
