Securities Technology
Securities firms in Indonesia require robust trading technology to serve both retail investors and institutional clients. Online trading platforms must handle hundreds of thousands of concurrent users with zero downtime during exchange hours, while institutional desks need sophisticated Order Management Systems (OMS) with FIX protocol connectivity to IDX JATS. Arunika Consulting helps securities firms implement comprehensive trading technology including retail online platforms, margin trading systems, automated back-office settlement, and regulatory compliance infrastructure aligned with POJK 23/2017.
Compliance Warning
This industry is considered high risk and may receive closer attention from tax authorities. Professional tax consultation is strongly recommended.

Frequently Asked Questions
What is the architecture of a modern online trading system?
Modern online trading follows a microservices architecture: front-end applications (web and mobile, typically React Native or Flutter) connect through an API gateway with authentication and order validation middleware. The Order Management System handles risk checks and routes orders to IDX JATS via FIX protocol. Market data streams are served via WebSocket from IDX multicast feeds. Back-office systems handle settlement, portfolio updates, and general ledger posting. Message queuing with Apache Kafka provides decoupling between components.
How does margin trading work in Indonesian securities?
Margin trading allows clients to borrow funds from the securities firm to purchase stocks, using existing holdings as collateral. The margin system continuously monitors collateral value against market prices. If the collateral ratio falls below the maintenance threshold, the system generates automatic margin calls. If the client fails to meet the margin call, the system triggers automated force-sell of positions. All margin parameters must comply with OJK regulations on maximum leverage and eligible collateral.
What is MKBD and why is it critical for securities firms?
MKBD (Modal Kerja Bersih Disesuaikan / Adjusted Net Working Capital) is the minimum capital adequacy requirement for securities firms in Indonesia. It must be calculated daily and reported to OJK. Firms falling below the MKBD threshold face trading restrictions or license suspension. Automated MKBD calculation systems aggregate positions, apply haircuts based on risk categories, calculate open positions, and generate daily compliance reports with alerting for potential breaches.
How do securities firms ensure system availability during trading hours?
Production systems must be deployed across primary and disaster recovery data centers with automatic failover. Load balancers distribute traffic across redundant application servers. Database clusters provide high availability with synchronous replication. Regular load testing simulates peak trading volumes. Business continuity plans are tested quarterly. OJK requires documented disaster recovery procedures and maximum downtime tolerance defined in service level agreements.
What key performance metrics matter for online trading platforms?
Critical KPIs include: order response time (target <500ms round-trip), platform availability (target 99.99% during trading hours), concurrent user capacity (peak load handling), order fill rate at best price, mobile crash-free rate (target >99.9%), and first-call resolution rate for support. Regular performance monitoring and capacity planning ensure consistent service quality.
Will system migration disrupt daily operations?
We usually use a parallel-run approach so the old and new systems operate together during transition, reducing downtime and data risk.
Can accounting software connect to POS and bank data automatically?
Yes. We design API and import workflows for POS, marketplaces, and bank statements to reduce manual entry and reconciliation errors.
Which software is best for my industry?
The right choice depends on transaction volume and complexity. We assess your workflow before recommending cloud accounting, POS, ERP, or dashboard tools.
