Switching RIA Custodians? Your Trading Doesn’t Have to Change
When a firm changes custodians, the goal is for clients to barely notice. Their portfolios should be rebalanced on the same schedule, their cash put to work the same way, and their questions answered by the same advisor they’ve always worked with. Consistency is what protects the client experience during a move.
Keeping things steady for clients is also what makes a custodian move so hard on the advisor.
Accounts transfer in waves, some households are still at the old custodian while others have landed at the new one, and the advisor is the one keeping it all on track, usually on top of a full client calendar.
Trading is one piece of that load the advisor doesn’t have to carry alone.
With the right support in place, a firm can keep the same models, the same rebalancing rhythm, and the same trading process on both platforms while accounts move over one at a time. From the advisor’s seat, the trading looks the way it did before the move started.
Here’s why custodian changes are back on the table, what a move really involves, and how to keep trading steady through the transition.
Why Custodian Changes Are Back in the Conversation
On October 1, 2026, Fidelity told existing RIA custody clients that they need at least $100 million on its platform by June 30, 2027, or they’ll need to move custody elsewhere (WealthManagement.com). Fidelity already requires $100 million from new firms joining its custodial platform, but this is the first time it has applied that minimum to firms already there (Financial Planning).
The fine print matters. “The threshold is based on assets held at Fidelity and not a firm’s total AUM” (AdvisorHub), so a $150 million firm with $60 million at Fidelity is still below the line.
Fidelity says the change affects a few hundred firms (WealthManagement.com) and has acknowledged the work ahead for them: “We recognize that change requires thoughtful planning,” a spokesperson said, adding that Fidelity “has committed to providing firms with time to evaluate their options” (AdvisorHub).
For those firms, and for any firm weighing a move for its own reasons, the timing creates an opening. A custodial change is a moment when a firm’s operations are already open for review.
How Does a Custodian Transition Impact Daily Trading and Portfolio Rebalancing?
A custodian transition fractures portfolio administration into two parallel environments. While ACATS transfers settle over weeks, advisors must rebalance accounts at both old and new custodians simultaneously. Without dedicated multi-custodian trade execution, firms face severe cash drag, delayed model updates, and increased compliance risk as client accounts straddle two platforms.
During a transition, households rarely land at once. A husband’s IRA might transfer in three days, while the wife’s trust account remains pending for three weeks. Without an institutional desk managing both sides, advisors waste hours manually auditing positions across disparate portals.
What Are the Best Strategies to Avoid Cash Drag and Drift During an RIA Move?
The most effective strategy is partnering with an agnostic outsourced trade desk like Advisor Logistics that executes orders across both platforms concurrently. By submitting model allocations through a single dashboard, traders immediately deploy incoming cash, harvest tax losses, and rebalance transferred holdings without waiting for full firm-wide account completion.
Cash sitting uninvested during market rallies creates measurable performance drag that erodes client trust. Systematic execution ensures that dividends, transfers, and contributions are deployed according to model targets within 24 hours of clearing.
Which Custodians Support Seamless Block Trading and FIX Order Routing for RIAs?
Leading institutional custodians—including Charles Schwab, Fidelity Institutional, BNY Pershing, Raymond James, Goldman Sachs Custody, and Altruist—all support FIX protocols and block trading. Advisor Logistics integrates directly with each custodian’s institutional desk, enabling aggregated block allocations and standardized trade settlement across multi-custodial firm architectures.
Advisors do not need to become technical experts in each custodian’s proprietary trade interface. Our trading desk handles order validation, FIX connectivity, and end-of-day execution reports directly.
Multi-Custodian Trading Workflow Comparison
The table below outlines how leading RIA custodians handle institutional order routing, block trading, and asset thresholds, and how Advisor Logistics supports firms across each platform:
| Custodian Platform | Custody Minimum | FIX Protocol & Block Trading | Trade Settlement & Allocation | Advisor Logistics Operational Support |
|---|---|---|---|---|
| Charles Schwab Institutional | $0 (no firm AUM minimum) | Schwab Advisor Center / FIX | Daily T+1 settlement via omnibus & block | Full daily model trading, drift correction, cash |
| Fidelity Institutional | $100M firm custody minimum | Wealthscape / FIX | Block trade allocations & mutual fund cutoffs | Dual-platform concurrent trading during moves |
| BNY Pershing | Evaluated on firm size | NetX360 / FIX order routing | Global execution & multi-currency clearing | Complete block execution & UMA reconciliation |
| Raymond James | Evaluated on firm profile | RJ Custody Direct / FIX | Synchronous allocations & fixed income desk | Custom household rebalancing & overlay |
| Goldman Sachs Custody Solutions | Tiered institutional focus | Goldman Digital Gateway / FIX | Institutional prime routing & alternative assets | Direct indexing & institutional block execution |
| Altruist | $0 minimum, tech-forward | Modern API & FIX routing | Fractional shares & automated digital trades | Algorithmic rebalancing & tax-loss harvesting |
A Custodian Move Is More Than Paperwork
Tim Welsh of Nexus Strategies put it plainly: “Nine months sounds generous until you account for what a custodial move involves” (WealthManagement.com).
Winthrop & Co. lists the work that has to happen for every household: new account paperwork, the transfer of assets, re-established standing instructions, and reconnected technology, including “portfolio management, trading, billing, performance reporting and the CRM.” It adds that “the count of households drives the effort more than the dollar amount” (Winthrop & Co.).
That second point is easy to miss. A firm with 150 smaller households can face more transition work than a firm with 40 larger ones.
Look closely at that list and you’ll see trading sitting right in the middle of it.
Whether or not a firm planned to rethink how it trades, trading is one of the systems that has to be reconnected and set up again during a move.
The Question Most Firms Skip: Who Handles the Trading?
Most firms going through a custodian change focus on the transfer itself. Fewer stop to ask who will handle trading on the other side, and many don’t realize there may be a more efficient way to do it than the setup they have today.
At smaller firms, trading often falls to the advisor. That time adds up. Kitces Research found that the investment management slice for the average advisor was 11% of their time. In a study of 745 advisors, AssetMark found that advisors who outsource investment management for at least 20% of their client assets save 9.1 hours per week on average.
Both figures cover investment management broadly, not only trading, and AssetMark’s figure likely includes advisors who hand off investment decisions along with the day-to-day work.
Still, the takeaway is hard to argue with. A move forces a firm to rebuild its trading setup. Rebuilding it the same way by default is still a choice, and one that may be costing both time and money.
Three Traditional Ways to Handle Trading, and the Trade-Off Each One Carries
In our comprehensive operational guide, The Leader in Outsourced Trading, we lay out the three paths advisors have traditionally had as their firms grow:
- Do it yourself: This costs the advisor’s time. Hours spent on trading and administration are hours not spent on clients and business development, which puts a ceiling on growth.
- Hire in-house: This costs salary, benefits, software, and management time ($105,000–$150,000+). It also creates a single point of failure. When your one trader is sick or on vacation, the advisor is back in the trading seat.
- Hand it to a third-party money manager (TPMM) or TAMP: This saves time, but often means giving up control of asset selection, models, and trade decisions, usually at a 20–50 bps cost to the firm or client.
Outsourced trading is the high-leverage fourth path. The advisor keeps 100% of the investment decisions, and a dedicated team of traders and portfolio administrators handles the trading, rebalancing, and day-to-day portfolio administration across 30,000+ accounts and $8+ billion in client assets.

Build a Trading Setup That Isn’t Tied to One Custodian
Welsh offered one more piece of advice for firms weighing their options: “Ultimately, your custodian is a vendor, not a partner any more. Know how they get paid, get commitments in writing, and always know how you’d leave” (Financial Planning).
From where we sit, knowing how you’d leave includes creating a plan for trading. A trading process that moves with the firm makes this transition smoother and the next one easier.
That’s where consistency matters most. During a move, a firm is effectively running on two platforms at once. Some accounts are still at the old custodian, some are already at the new one, and households are changing over one at a time. A trading team that already works on both platforms can keep rebalancing and trading on schedule across every account, wherever it happens to sit that week. The advisor’s models, preferences, and process don’t change, and neither does the way they send in requests.
How Advisor Logistics Helps
Advisor Logistics works with advisors across a range of custodians, including Charles Schwab, Fidelity, Pershing, and Raymond James. We work inside your existing custodial accounts, so your client relationships, account structure, and paperwork stay as they are.
You keep your models and your investment decisions. Our traders and portfolio administrators handle the trading, rebalancing, and day-to-day portfolio administration.
If you’re moving between two of those custodians, we trade on both platforms throughout the transition, so your trading process doesn’t need to change at all from your perspective.
That consistency extends to how your team works with us. Instead of learning a new custodian’s trading tools in the middle of a move, your team keeps using one intuitive ALX dashboard to submit requests and monitor progress, no matter which custodian an account sits at that day. Your staff learns to use our simple, intuitive dashboard, and we handle the custodial platforms behind the scenes.

Frequently Asked Questions
When is Fidelity’s deadline for RIAs under $100 million?
June 30, 2027. Existing RIA custody clients with less than $100 million at Fidelity must meet the minimum or transition custody elsewhere. Firms have an operational window to plan account transfers, re-establish trading authorizations, and select alternative custodial partners without disrupting ongoing portfolio management.
Do assets at other custodians count toward Fidelity’s $100 million minimum?
No. The $100 million threshold is calculated exclusively on assets held directly on Fidelity’s custodial platform, not the firm’s overall AUM. A firm managing $150 million total with only $60 million at Fidelity remains subject to the platform minimum and must evaluate custodial options.
Can Advisor Logistics manage trading during an RIA custodian transition?
Yes. Advisor Logistics actively trades across Charles Schwab, Fidelity, BNY Pershing, Raymond James, Goldman Sachs, and Altruist. During a transition, our traders manage models simultaneously across both legacy and destination custodians, ensuring client portfolios remain fully invested, rebalanced, and cash-managed without missing a market day.
How does multi-custodian trading prevent client experience disruptions during a move?
Accounts transfer in rolling waves over weeks or months. By centralizing order routing through Advisor Logistics, advisors submit model updates and cash requests through one interface. Portfolios at both custodians are rebalanced simultaneously, preventing model drift, cash drag, or noticeable performance divergence between transferred and untransferred accounts.
Does an RIA need to license new rebalancing software for a new custodian?
No. Changing custodians frequently triggers unexpected software migration costs and setup fees ranging from $20,000 to $100,000. Partnering with Advisor Logistics eliminates software licensing burdens entirely because our trade desk connects to all major custodial trade routing networks using our proprietary and enterprise trade stack.
