Introducing Broker: Who Holds the Money

Michael Whitman · Trading since 2017, full-time since 2020 · Reviewed 2026-09-06

An introducing broker holds the client relationship and takes the order, while a separate clearing firm settles the trade, holds the cash and securities, issues statements and enforces margin. The customer agreement names that clearing firm, and protections and margin authority follow it, not the brand on the app.

How it works

The firm you sign with is not always the firm holding the money. One takes the order and provides the relationship; another clears the trade, settles it and holds the cash and the securities.

An introducing broker owns the client-facing half of that split. It does the marketing, opens the account, answers the phone and accepts the order. It does not touch your assets.

The clearing firm does everything downstream. It handles settlement, holds the cash and securities in custody, issues the statements and enforces the margin rules on your margin account.

A calmly advancing stretch of the long price series with a slowly rising equity curve beneath it. The headline on the chart reads: Which lets a small firm operate without clearing capital. — Which lets a small firm operate without clearing capital. Illustrative chart - not real market data.

The split exists because clearing is expensive. It demands capital, settlement systems and regulatory permissions that a small or specialised firm cannot economically carry on its own.

Why the arrangement is normal

A good clearing relationship is an advantage, not a warning sign. It lets a small specialist firm offer custody and execution quality it could never build alone, which is why the structure is so widespread.

It is paid a share of the commission or the spread. Illustrative chart - not real market data.

How the introducing firm gets paid tells you what it wants. Usually a share of the commission, a mark-up on the bid-ask spread, or a rebate arrangement tied to the volume it sends.

A strongly rising stretch of the long price series with an account curve breaching its limit. The headline on the chart reads: So check who clears before you check anything else. — So check who clears before you check anything else. Illustrative chart - not real market data.

That incentive is worth reading plainly. A firm paid per round trip is paid more when you trade more, which is a fact about the arrangement rather than an accusation about the firm.

A choppy, directionless stretch of the long price series. The headline on the chart reads: Both firms are registered, and only one holds the cash. — Both firms are registered, and only one holds the cash. Illustrative chart - not real market data.

Both firms are normally registered, and only one holds your money. Registration of the introducing firm says nothing about who has custody of your assets.

A declining stretch of the long price series. The headline on the chart reads: And the protection follows the clearing firm, not the branding. — And the protection follows the clearing firm, not the branding. Illustrative chart - not real market data.

Investor-protection schemes attach to the custodian. Where such a scheme exists it addresses a failed custodian, never a bad trade — losses from your own positions are yours. Check the scheme and the register in your own jurisdiction.

In practice

A layer of intermediation is a layer of cost. The commission share or spread mark-up has to come from somewhere, and it comes out of what you pay per round trip.

The order still reaches the same market in the end. It is routed onward to market makers or an exchange, and the resulting volume prints like anyone else’s.

The arrangement is most common in futures and forex. It also underpins white-label apps, where a familiar front end is a shopfront for someone else’s brokerage.

In a fast market the clearing firm decides what happens. It sets margin requirements, and after an opening gap it can raise them or liquidate positions outright.

So the margin call arrives from a firm you never signed with. Your own stop order and your chosen order types sit above a liquidation authority you did not select.

Costs are small per trade and relentless in aggregate. On this site’s shared 576-bar history a round trip costs 0.0098 price units, which is 2% of a median bar’s range and 45% of the smallest bar.

The check to run before you fund an account

The whole thing reduces to a short procedure. Open the customer agreement — not the marketing page, not the frequently asked questions — and find the paragraph naming the clearing firm. It is normally near the front, under a heading about the clearing arrangement or the carrying broker.

Then look up both names on your regulator’s public register. Search each firm separately and confirm its registration status and its permissions. A firm authorised to introduce business is not necessarily authorised to hold client assets, and the register will say which.

Finally, confirm who has custody and where the statements come from. The firm that emails your statement is usually the one holding the assets, and that is the firm whose failure any protection scheme would address.

Do all of this before you transfer money. Afterwards, when something has already gone wrong, the same reading buys you almost nothing.

What an introducing broker is not

Not a scam by structure. The arrangement is ordinary, disclosed and used by long-established firms.

Not the custodian of your money. The clearing firm holds the cash and the securities.

Not a prop firm. Those trade a firm’s own capital under a challenge, not your account.

Not a source of extra protection. Adding a second name to the chain does not add a second safety net.

When it fails

A sideways, range-bound candlestick series. The headline on the chart reads: In a quiet market the structure never matters at all. — In a quiet market the structure never matters at all. Illustrative chart - not real market data.

In a quiet trading range the structure never matters at all. It becomes visible only under stress, which is exactly when you have no time to read a contract.

The disclosure is real but buried. The clearing firm is named in the agreement rather than on the app, so most account holders genuinely do not know who has their assets.

Margin authority surprises people. A clearing firm can raise requirements mid-session and close positions, including positions carried on leverage that were comfortable an hour earlier.

Support is split down the middle. The introducing firm answers the phone but cannot move a settled position, so urgent problems bounce between two organisations.

Order routing is opaque. How the flow is paid for, including any payment for order flow arrangement, sits below the layer you signed with.

Protection is misread. People assume a scheme covers bad outcomes; it addresses a failed custodian, not a losing trade, and the terms differ by jurisdiction.

The original data

A strongly rising stretch of the long price series, cut short at the decision bar. The headline on the chart reads: A small firm, an unknown clearer. Open it? — A small firm, an unknown clearer. Open it? Illustrative chart - not real market data.

The published conversation is about brands, not structure. Scanning the 31,760 trading and investing videos in research/search-study-corpus.jsonl, research/broker-coverage.json finds 116 videos with “broker” in the title, median 27,768 views, across 76 channels. Named platforms dominate: thinkorswim appears in 184 titles, webull in 108, robinhood in 76.

The absence is the finding. “Clearing firm” appears in zero titles, and so does “payment for order flow”. “Introducing broker” appears once — one video, 6,042 views, one channel.

So the published conversation is entirely about which brand to sign up with. None of it is about who actually holds the money or how the order is paid for. Before opening an account, read the customer agreement for the clearing firm’s name and look both firms up on your regulator’s public register.

Once you know who clears, choosing a broker becomes a comparison of costs and permissions rather than advertising. Settlement is the process the clearing firm performs on your behalf, and it explains why custody sits where it does. And prop firms are a separate structure, confused with this one because both put a second company between you and the market.

What I actually do

The first thing I look for in a new account is the name of the clearing firm, and it is rarely on the homepage. I open the customer agreement, find who actually holds the assets, then look up both names on the regulator’s register before I move any money. It takes very little time, and I have walked away from accounts because of it. Doing it afterwards, when something has already gone wrong, is worth almost nothing.
