Max Nominal Exposure
When enabled, this rule limits the projected nominal exposure of the current instrument, regardless of stop distance.
projected_net_position = current_signed_position + signed_candidate_quantitynominal_exposure = abs(projected_net_position) * price * PointValue
Buys are positive and sells are negative. PointValue is the instrument’s monetary value per price point per contract or unit. The resulting nominal amount must be expressed in a currency compatible with the account limit. It is the position’s nominal market value, not its potential loss at the stop.
For example, a projected net position of 3, a price of 100, and a PointValue of 10 give a nominal exposure of 3,000 in the instrument’s currency. A compatible limit of 2,500 blocks the operation.
The calculation does not aggregate other instruments in the portfolio and does not reserve exposure for pending entry orders.
There is no implicit FX conversion. If instrument and account currencies differ, explicit conversion data is required. Missing required position, price, instrument, or conversion data leaves the check Pending/Warning and prevents submission without confirming a violation or latching the circuit breaker.
With the rule enabled, 0 is an exposure limit. Only disabling the rule skips it. A nominal cap does not guarantee a fill price or eliminate slippage.
