Every open stop across your funded accounts draws on one risk budget

Open stop risk is the dollar amount you lose if a position hits the stop you set when you opened it: contracts × ticks from entry to stop × dollar value per tick. Compute it per position, per account, in one currency, and add. In the worked example below, stops of $175, $120 and $105 across three accounts make a desk total of $400. That is the number the budget governs.

Two things stay out of the sum. Advertised account size stays out because it labels a simulated balance; what an account can actually cost you is capped by its drawdown allowance plus the fee to replace it, a small fraction of that label. Open profit and loss stays out because the budget measures what the market can still take from here; losses already realized show up in the next section's comparison as shrunken drawdown room.

A copied trade multiplies. The same entry with a $175 stop carried on three accounts is $525 of desk risk from one decision, the copies synchronize rather than diversify, because one adverse move hits all three stops on the same tick.

Three limits apply at once, and passing one clears nothing about the other two. Your own per-trade and session stops come first. Each firm's rules come second: a drawdown floor (a balance level that ends the account if equity touches it) and, at some firms, a daily loss limit. The desk ceiling you chose comes third. In the worked example, every account can be inside its own firm's rules while the $400 desk total sits $50 over the $350 ceiling; the ceiling is the only limit of the three that sees the overlap.

Drawdown room (the dollar distance between current equity and the floor) is computable only when you know how the floor moves and where it stops. A floor that trails follows your balance upward: some firms publish that the trail stops at the starting balance, at least one publishes that it trails for the life of the account, and where a firm publishes nothing, the honest state is unknown. Enforcement is a separate fact from movement: across the eight firms in NANO's sourced rule snapshot, six publish wording that enforces the floor against live open equity, an intraday dip through the line ends the account even where the line itself only moves at the daily close. The other two publish no timing sentence at all, and no firm in the snapshot has earned a close-only reading.

So when an account's floor trails intraday, its drawdown type is unpublished, or your logged balance history has gaps, do not fill the blank with the full published drawdown figure. That account still contributes its open stop risk to the $400-style desk total like any other; it contributes zero to your estimate of how much more the desk can absorb.

The tempting move is to short an index on one account, hold a metals position on another, and call the desk hedged because the tickets look different. Equity indexes move together, dollar-priced instruments share dollar shocks, and a platform outage or dropped connection hits every account on that platform in the same minute. None of that shows up in symbol names or firm names.

The arithmetic therefore starts gross: assume every stop can hit in the same hour until you have evidence it cannot. The $400 in the worked example is exactly that assumption, three stops, one bad hour. If two positions genuinely offset and you want to budget below gross, write the offset down as its own claim and check it against what actually happened, instead of burying it in the account count.
