A trading room on 4X Solutions is simple to describe: each trader trades their own account — demo or live — and a single live account follows all of them at once. You set every trader’s allocation independently. You give every trader their own loss budget. And when a budget is spent, that trader is cut from the book automatically — while the other nine trade on.
No spreadsheets. No manual netting. No “I’ll reduce his size on Monday.”
Meridian Desk runs ten traders on demo accounts, blended into one live book.
| Trader | Allocation | Loss budget | Notes |
|---|---|---|---|
| Alba | 20% | $8,000 | Senior — largest allocation |
| Kofi | 15% | $6,000 | |
| Priya | 15% | $6,000 | |
| Marek | 10% | $4,000 | |
| Sofia | 10% | $4,000 | |
| Dan | 8% | $3,000 | |
| Yuki | 8% | $3,000 | |
| Tomás | 6% | $2,500 | |
| Leah | 5% | $2,000 | New — proving out |
| Ossian | 3% | $1,500 | Trial — gold only (instrument whitelist) |
Marek has a bad week: two losers closed, one open position underwater. His Capital to Risk budget — open risk plus realised losses — hits its $4,000 ceiling. His next trade doesn’t copy. Nobody intervened, nothing was missed in a meeting: the budget did its job, and the other nine traders’ signals kept flowing.
Marek asks why his trade didn’t reach the book. The desk doesn’t guess — the missed-trade record for that exact trade says capital-to-risk exhausted, with a timestamp. The conversation takes thirty seconds and zero ambiguity.
The PM reviews Marek’s open position, decides the thesis is dead, and rather than deleting his configuration, suspends his following — everything about his setup is preserved for when he’s re-instated with a fresh budget next month.
Leah is up 14% on the month with tidy drawdown. Her allocation moves from 5% to 8% — one setting, applied from her next trade, no re-papering.
A volatile CPI print puts the whole book under pressure. The account’s Warning drawdown level fires and the PM is emailed before anything is forced. The book recovers without touching the Soft Stop — but if it hadn’t, new copying would have paused automatically, and past the Hard Stop, positions would have been closed out. Three independent enforcement points, none of them requiring the PM to be at a screen.
That’s the product: allocation, budgets, benching, and book-level protection — each one a setting, each one enforced by the platform, each refusal recorded with a reason.
Because signal accounts can be demo accounts, a room doubles as a trader pipeline:
Every stage is observable: per-trader trade events, missed trades with reasons, and account-health notifications by email, SMS, or HMAC-signed webhook into your own desk tooling.
Yes — demo accounts work as signal sources exactly like live ones. Most rooms evaluate traders on demo and put only the blended account live.
Their trades stop copying to the book automatically. Everything else continues. The refusal is recorded per trade with the reason and a timestamp.
Yes — percentage to mirror is per trader, and the new allocation applies from that trader's next trade. Positions already open are not resized.
Yes — suspend the following; the configuration is preserved and can be re-enabled at any time.
The account’s own risk stack: a three-level drawdown ladder measured from the high-water mark, an equity stop that closes everything, and per-position drawdown limits — all enforced server-side.
There is no fixed limit. A blended account can follow as many traders as you need, each as an independent following with its own allocation and loss budget.
Allocation, budgets, and enforcement — per trader, per book, per trade. On infrastructure that has copied trades for 18 years across 50,000+ connected accounts.
