Module order_builder 

Order message builder for dYdX v4 protocol.

This module converts Nautilus order types to dYdX proto messages (MsgPlaceOrder, MsgCancelOrder). It centralizes all order building logic including:

• Market and limit order construction
• Conditional orders (stop-loss, take-profit)
• Short-term vs long-term order routing based on OrderLifetime
• Price/quantity quantization via market params
• Dynamic block time estimation via BlockTimeMonitor

The builder produces cosmrs::Any messages ready for transaction building.
