Intermediary Routing Fee
The Formal Definition
A secondary clearing, pass-through, or technology access fee assessed against an order as it moves through upstream clearing corridors, execution networks, or regional exchange hubs.
Net Execution Drag = Public Ticket Commission + Pass-Through Intermediary Toll + Exchange TAF/SEC Fee
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Intermediary routing fees are the fine-print toll booths of trading. You think you're paying a flat $1 commission, and then your monthly trade confirm arrives with mysterious 'routing access,' 'ECN liquidity removal,' and 'regulatory fee' deductions. It's the broker equivalent of a hotel resort fee."

Real-World Example: Scenario Breakdown
Examining the real numbers for: An active algorithmic trader executing 20,000 shares across multiple electronic communication networks (ECNs)
| Execution Metric | Rebate-Optimized Maker-Taker Trader | Unoptimized Passive Order Router |
|---|---|---|
| Fee / Rate | $0.0035/share base rate | $0 advertised base ticket |
| Spread / Buffer | Posted passive liquidity on venues that offer maker rebates (e.g., BATS or ARCA) | System routed aggressively through an upstream wholesale network that slapped on pass-through removal fees |
| Execution / Status | Exchange credited back $0.0020 per share in liquidity rebates against broker routing fees | Assessed an unexpected $0.0030/share intermediary surcharge on 20,000 shares |
| Total Cost / Result | Turned exchange routing mechanics into an operational discount | Surrendered trading profits to unexpected pass-through tolls |
How Brokers Weaponize This Term
Review your monthly trade confirmations for lines labeled 'ORC' (Order Routing Charge) or 'ECN Pass-Through'. If your broker passes through liquidity removal fees when you take liquidity but keeps the exchange rebate when you add liquidity, you are operating under an asymmetrical pricing schedule.
Broker Evaluation Matrix
Cole Approves
Interactive Brokers: Under its Tiered pricing model, fully passes through all exchange rebates directly to clients, allowing negative net commissions on liquidity-providing limit orders.
Read Audit →Cole Flags / Avoids
Fixed-Tier Legacy Platforms: Charges flat ticket commissions while pocketing all exchange maker rebates and quietly passing through third-party routing penalties.

What is an ECN pass-through fee?
It is a fee charged by an Electronic Communication Network (like Nasdaq or Cboe) when a market order takes resting liquidity off the order book.
How can I avoid intermediary routing charges?
Use passive limit orders that add liquidity to the book, or choose a broker with simple, transparent flat-rate pricing that absorbs all pass-through fees into a single ticket price.
