Smart Open Exposure · Why It Matters
Reference
Distribution of maximum drawdowns across simulated paths, overlaid on the gate zones - from Growth on the left to System Lock territory in the deep-red tail.
Why it matters
Accidentally exceeding the true risk budget rarely feels like a decision — it accumulates through carryover trades nobody re-counted. Smart Open Exposure makes the burden explicit at exactly the moment fresh risk is being authorized, and Total Active Risk After New Trades confirms the final exposure reality on every decision.
Where it lives
Within Smart Open Exposure, this is one load-bearing idea — worth its own page. The parent module frames it this way: Many traders size the next trade as if no open risk exists. MARS refuses the fiction: if a stop hasn't reached break-even, that trade still burdens the account, and fresh deployment must resize around it.
The stacking illusion
Each position sized correctly in isolation, opened in sequence, sums to an exposure no single decision approved — the invisible over-leverage that kills accounts run on per-trade discipline alone. Smart open-exposure exists because the dangerous unit is the portfolio moment, not the trade, and only the running sum sees it.
