The BigMarkt Architecture
BigMarkt is built in layers. Each layer is independently verifiable, and each is downstream of the one beneath it.
Proof Layer
Server-captured trade history.
A read-only Expert Advisor for MetaTrader 4 and 5 reads every fill from the trader's broker terminal and ships it to the journal in real time. Trades arrive timestamped server-side, with no manual edit path, no screenshot upload, and no after-the-fact rewrite. The journal entry is what the broker confirmed — nothing else.
Coordination Layer
Public leaderboards and verified rank.
Sanitized aggregate stats — win rate, expectancy, drawdown, R-multiple — are published per profile. Anyone can see a rank-ordered view of who is actually performing, with no email leakage and no self-reported numbers. Rank is downstream of proof.
Accountability Layer
The Trading Constitution.
Each trader writes their own rules — risk caps, stop-loss discipline, instrument limits, minimum R:R. The journal checks every verified trade against those rules and publishes an adherence score. Reputation here isn't only how much you made; it's whether you followed the rules you set for yourself.
Community Layer
A community-owned reputation network (planned).
Where this is headed: a verified track record that's portable and owned by the trader, not locked inside one broker or platform. This is a long-term direction, not a shipped feature — built only on verified history, and only once the foundation beneath it is proven.
How verification works
The journal is the source of truth. Every entry traces back to a broker fill — not a screenshot, not a claim.
Broker fills the trade
The trader's read-only EA captures the fill the moment it happens on their terminal.
Journal records it
The fill is written to the journal server-side — timestamped, core fields locked, with no manual edit path.
Reputation updates
Public stats, leaderboard rank, and Constitution adherence recompute from that verified record.
BigMarkt never holds broker credentials, never routes orders, and never places trades. It reads what the broker confirms and records it. Information moves; orders don't.
Broker compatibility
BigMarkt ships an Expert Advisor for MetaTrader 4 and MetaTrader 5. Most regulated retail FX/CFD brokers are supported out of the box. cTrader and broker-API integrations are on the roadmap.

“The journal entry is a record of what happened — verified, not self-reported.”
BigMarkt is a journaling and verification tool. The EA is read-only: it reads your trade history and never places, modifies, or closes a position. Nothing here is investment advice, and BigMarkt does not advise, manage funds, or trade on anyone's behalf.
That boundary is deliberate. BigMarkt's job is to make a trading record impossible to fake — and to leave every trading decision with the trader.
