Max exposure per event
In one line: a cap enforced at order entry — it cannot be breached, only refused.
The cap#
Maximum exposure to any one event is 5%PROVISIONAL of starting balance — $250 at the beta size — measured at cost.
Measuring at cost, rather than at mark, means a winning position that grows past the cap is never force-trimmed. You bought within the rule; the rule is satisfied.
What counts as one event#
Related markets on a single real-world occurrence count as one event. The terminal shows the grouping before you commit, so the number you are checked against is never a surprise.
Refused, not breached#
This rule cannot be breached, only refused.
It is enforced at order entry: an order that would exceed the cap is rejected with the figure that would have been exceeded. There is no version of this rule that ends your account.
