Spot Trading & Fees

Spot trading is the core market function of WorldX’s early stage.

Purpose

Spot trading must be:

• Deterministic and fair

• Transparent in fees and outcomes

• Auditable through user records

• Resilient during volatility with defined behavior

Matching Rules

WorldX commits to:

• Publish matching priority logic (e.g., price-time or equivalent)

• Not introduce hidden execution rules without a changelog

• Provide consistent behavior under normal conditions

Order Lifecycle

Users can always see:

• Order creation time

• Order status transitions (open, partially filled, filled, cancelled, rejected)

• Fills and average price

• Fees applied per fill

• Reason codes for rejections/cancellations where applicable

Fee Transparency Rules

WorldX commits that:

• The fee schedule is published and versioned

• Fees are itemized per trade

• Tier rules are documented

• Promotional fee changes have effective dates and changelog entries

Edge Cases and Stress Behavior

A GitBook-grade exchange doc must define:

• Behavior if the market order exceeds the liquidity depth

• Behavior during maintenance windows

• Behavior during partial outages (read-only mode vs trading disabled)

• Cancellation guarantees during disruptions

• How users are notified when trading is impacted

WorldX treats these behaviors as part of trust: ambiguity is where disputes and fear begin.
