Max margin = 15% of $3200 = $480; at 4x leverage that allows $1920 notional. The requested $5760 notional exceeds this limit, so it is not compliant.

With max 15% margin ($480) and 4x leverage, max notional is $1920. 5760 requires $1440 margin, exceeding limit, so non-compliant.

The requested 5760 notional violates the hard rule capping a single position's notional at 20% of equity, which strictly limits the maximum notional to $640 regardless of other margin rules.

A $5760 notional at max 4x leverage requires $1440 margin = 45% of $3200 equity, breaching the 15% margin cap. Max margin = 0.15 × $3200 = $480; at 4x leverage, max notional = $480 × 4 = $1920.

The requested $5760 notional breaches the mandate limits. The binding maximum is 20% of $3200 equity, so max notional is $640.

A $5,760 notional at 4x leverage requires $1,440 margin (45% of equity), violating the 15% max-margin rule ($480 cap). Max compliant notional is $480 × 4 = $1,920.

A 5760 notional long on SOL is not compliant because the maximum notional allowed under the rules is 1920. The rules limit a single position to at most 20% of equity as notional (not margin) and leverage at most 3x. The house rules provided (15% margin, 4x leverage) are overridden by the hard rules: max 20% of equity as notional and max 3x leverage. With $3200 equity, max notional is $640 (20% of equity) or $9600 (3x leverage), but the binding constraint is the 20% of equity rule, which gives $640. However, the question specifies 'house rules: max leverage 4x, and a single position may commit at most 15% of equity as margin (collateral).' This means margin is 15% of equity = $480. With 4x leverage, notional = margin * leverage = $480 * 4 = $1920. Therefore, the maximum notional allowed is $1920, and the requested $5760 is not compliant.

The proposed notional of $5760 requires $1440 in margin at 4x leverage, which exceeds the 15% equity margin limit ($480). The maximum compliant notional is $480 margin * 4x leverage = $1920.
