Risk Controls

What You Get

Every trade on PerpDesk passes through Brix's risk filtering before it executes. This isn't optional — it's a deterministic set of checks that protect you from oversized positions, excessive leverage, and concentrated exposure.

No trade reaches an exchange without passing these checks first.

Pre-Trade Filtering

Before any trade executes, Brix checks:

• Zero balance — rejects if you don't have available funds
• Max concurrent positions — rejects if you've hit your position limit
• Daily loss limit — rejects if you've already hit your maximum daily drawdown

If any of these fail, the trade is blocked immediately. No exceptions.

Position Sizing and Leverage

Brix enforces position sizing and leverage limits based on your experience tier:

These limits are hard caps. Even if you or an agent requests a larger position, Brix will not allow it.

First-Trade Caps

New traders start with reduced limits on their first trades. This prevents an inexperienced user (or a misconfigured agent) from immediately deploying maximum size.

Confidence-Based Scaling

When Riven generates a trade recommendation, it includes a confidence score. Brix uses this to scale position size — higher confidence recommendations can use more of your available sizing, while lower confidence trades are automatically reduced.

Exposure Controls

Brix tracks your total portfolio exposure in real-time:

• Max total exposure — hard cap on how much of your balance can be deployed across all positions
• Reservation accounting — pending orders are deducted from available balance, so you can't accidentally overcommit
• Same-direction concentration — if you're building multiple positions in the same direction, Brix warns you about concentrated risk

Warnings

Not everything is a hard block. Brix also surfaces warnings when you're approaching limits:

• Approaching daily loss limit — you're getting close to your max daily drawdown
• Near max positions — you're one or two positions away from your cap
• Same-direction concentration — multiple open positions betting the same way

These give you a chance to adjust before hitting a hard stop.

How Agents Interact with Risk Controls

Risk controls apply equally to manual trades and agent-initiated trades:

• Riven generates recommendations. Brix evaluates each one against your personal limits before it can execute.
• Koda handles execution. If Brix rejects a trade, Koda won't submit it to the exchange.
• Brix also scores each recommendation against your personal strategy profile and evaluates portfolio-level risk impact.
