# Orders and execution

> Overview of order types, the matching engine, and auto-deleveraging on Roxom's trading platform.

### Order types

The various instructions for trades, including Limit, Market, Stop-Limit, and Stop-Market orders *(detailed in* [*Order types and execution rules*](../order-types-and-execution-rules)*).*

### Matching engine

Roxom's trade-matching system that executes orders based on price-time priority during live trading hours. It enforces all trading rules and risk checks described in this rulebook.

### Auto-Deleveraging (ADL)

A last-resort loss-distribution mechanism that automatically deleverages (reduces) opposing traders' positions to cover unallocated losses in extreme scenarios where the Insurance Fund is insufficient. ADL ensures the exchange as a whole remains solvent by sharing losses among profitable traders *(see* [*Auto-Deleveraging section*](../auto-deleveraging-adl) *for detailed information about our system).*
