How To Solve Scaling Before Your Next 1 Million Order Rebalance
In the world of high-volume wealth management, “scale” is often a double-edged sword. Growing your AUM and client base is the goal, but for many firms, a massive rebalance event feels less like a victory and more like a stress test for a system that wasn’t built for the “Big Days.”
At Flyer, we believe your infrastructure should be a shock absorber, not a bottleneck.
This year, we set a new benchmark. During a single weekend rebalance event, the Flyer engine processed 1,000,000 mutual fund orders and 130,000 equity allocations for a major institution. Even at this extreme volume, our system operated at less than 30% CPU capacity.
Here is how we leverage our core pillars of Enterprise Strength, Elegant Simplicity, and Human-Guided Intelligence to turn massive scale into a competitive advantage.
1. Solving the “Custodian Bottleneck” with Elegant Simplicity
One of the greatest hurdles for large-scale trading isn’t just internal processing but the technical limitations of the custodians themselves.
For example, many major custodians (like Fidelity) impose strict limits on file sizes, often capping mutual fund orders at 25,000 per file every 15 minutes. For an Enterprise RIA trying to move 500,000 orders, this creates a manual “batching” nightmare.
Flyer solves this through autonomous precision. Our engine acts as a “buffer” and “slicer.” You send the entire block to Flyer via API or FIX; our system automatically queues and “drips” the orders to the custodian in compliant, perfectly timed batches. We transform a complex, manual workflow into a single, frictionless motion.
2. Built for the “Burst”: 600% Faster Performance
Scaling isn’t just about total volume; it’s about velocity. In early 2025, our continuous reinvestment in our internal architecture resulted in a 600% improvement in FIX-to-file processing speeds.
During peak “burst” periods where we see over 16,000 messages per minute, the Flyer platform maintains the speed and accuracy that enterprise firms demand. By keeping JVM heap usage below 15% and ensuring no “long-tail” latency outliers, we provide a single source of truth that remains stable when the market is most volatile. You get the speed of a high-frequency trading shop with the reliability of an institutional bank.
3. Human-Guided Intelligence: The “White Glove” Difference
No matter how autonomous the technology, we know that massive trading events carry high stakes. This is where our pillar of human-guided intelligence comes to life.
While our tech orchestrates the trades, our expert support teams provide “White Glove” weekend monitoring for major rebalance events. We don’t just provide a platform; we provide operational dexterity. Our teams are in the “war room” with you, monitoring system signals and ensuring that by the time the Monday morning bell rings, your trades are settled, your data is clean, and your team is ready for the next opportunity.
The Bottom Line
Scale should never be a ceiling on your firm’s growth. Whether you are executing 10,000 trades or 1,000,000, Flyer provides the intelligence and the infrastructure to ensure your mission-critical operations are handled with absolute precision.
