THE Main sequence Markets platform

Account Management

Manage broker accounts across execution venues, define reusable portfolio strategies, and allocate them as Virtual Funds within each account—so teams can monitor exposures, allocations, and drift with a complete, auditable holdings history.

The One Idea That Explains Everything

In real portfolio management, you must run two realities in parallel. Main Sequence keeps them separate, then links them through virtualization.

1. Accounting Truth

What the broker account actually holds.

Real tradable instruments
Hard assets
Venue executions

2. Exposure Intent

What you want the account to represent.

Strategy sleeves
Benchmarks & Targets
Model allocations
