Engineered to Match Real Japanese Market Rules

High-fidelity simulation requires strict enforcement of domestic Japanese statutory frameworks and operational conventions.

Strict Integer JPY Arithmetic

Japanese Yen carries zero minor currency units. Aegis strictly enforces non-decimal integer arithmetic across all order quantities, gross trade amounts, JSCC netting settlements, and BOJ-NET wire transfers.

Short Sale Regulation (SSR) & Uptick Rule

Enforces Cabinet Office Ordinance on Securities Transactions. Detects 10% price drops from previous close to trigger the SSR uptick restriction, requiring short orders to be executed above current market price.

FIEA Article 43-2 Asset Segregation

Simulates statutory customer asset segregation (bunbetsu kanri). Automatically calculates the required trust amount (shintaku hitsuyo gaku) and verifies daily balance compliance with domestic trust banks.
