Cash Account vs Margin Account for Day Trading (Good Faith Violations Explained)

Short answer: For a new day trader, a cash account trades speed for safety. You can't borrow, you can't lose more than you put in, and the pattern day trader rule never applied to it. The catch is that you can only trade with settled cash, and breaking the settlement rules can restrict you to settled-cash-only buying for 90 days or more. A margin account lets you reuse unsettled money and, with at least $2,000 of equity, borrow. Since June 4, 2026, brokers that have switched to FINRA's new rules have no $25,000 day-trading minimum. The price is interest, margin calls and the chance to lose more than you deposited.

TL;DR

• Cash account: pay in full, no borrowing, no shorting. Trades settle one business day later (T+1).
• Margin account: Reg T lets you borrow up to 50% of a purchase, and FINRA requires at least 25% maintenance.
• A good faith violation is buying with unsettled proceeds and selling before they settle. Freeriding is selling a stock you never paid for.
• Regulation T can freeze an account for 90 days after you sell a stock you haven't paid for in full. How many good faith violations trigger a restriction is broker policy, and brokers differ.
• At brokers that have switched, there is no $25,000 minimum, and borrowing still needs $2,000 of equity. Brokers that need more time may keep the old PDT rule until October 20, 2027.

Cash account vs margin account: side by side

What's the difference between a cash account and a margin account?

It comes down to whether your broker can lend you money. The SEC's margin bulletin puts the cash side plainly: "In a cash account you cannot borrow funds from your broker-dealer to pay for transactions in the account." In a margin account the broker lends you cash against your account. For the full explanation of borrowing, read what margin trading is.

The same bulletin adds: "Brokerage firms may allow you to have both a margin account and a cash account at the same time." It also warns that some applications make margin the default, so check which one you're signing up for.

How does T+1 settlement limit a cash account?

When you sell a stock, the cash isn't yours to reuse freely until the trade settles. Since May 28, 2024, most US stock trades settle one business day later. The SEC's example: "if you sell shares of ABC stock on Monday, the transaction will settle on Tuesday."

In a cash account you can buy with unsettled funds. What you can't do is sell that new stock before the money you paid with has settled. That one rule is behind most cash account violations.

A hypothetical Monday morning with $5,000 of settled cash (times ET):

1. 9:40am. Buy $2,500 of Stock A with settled cash. Sell at 9:55 for about $2,550. Fine.
2. 10:10am. Buy $2,500 of Stock B with the other settled half. Sell at 10:30 for $2,460, a $40 loss. Also fine. Profit or loss makes no difference to the rule.
3. 10:45am. Buy Stock C with Stock A's $2,550 of proceeds. The buy is allowed. Sell Stock C before Tuesday and you've committed a violation.
4. Tuesday morning. Monday's sale proceeds have settled. Selling Stock C now is fine, and your settled cash can fund new buys.

So with T+1, a trader who closes everything the same day gets one round trip per settled dollar per business day. For how much capital to start with, see day trading under $25k.

What is a good faith violation?

A good faith violation (GFV) is what step 3 becomes if you sell Stock C on Monday. In FINRA's words, it happens when "you purchase a security with cash from a transaction that hasn't settled yet and then sell the security before the proceeds used to fund the purchase have settled."

The name traces back to the wording of Regulation T. Without enough funds in the account, a broker may let you buy only if it accepts, in good faith, that you "will promptly make full cash payment for the security or asset before selling it." Sell before the money settles and you've broken that agreement.

How many before a restriction? Regulation T has no good faith violation count. Each broker sets its own (as published, checked October 2026):

• Fidelity: three good faith violations in a 12-month period mean "your brokerage firm will restrict your account" to settled-cash buying for 90 calendar days.
• Schwab: three in a 12-month period can restrict you to trading with settled cash for 90 days.
• Public (Public.com): a fourth GFV in a rolling 12 months restricts you to settled funds, and a fifth brings 90 days of sell-only.

The settled-cash restriction doesn't stop you trading. It stops you buying with anything but settled cash.

To avoid one, hold anything you bought with unsettled proceeds until those proceeds settle, or add new money to the account before you buy. Public's advice for avoiding a fifth is to "wait to place a buy until your sale has settled or add more funds to your account."

What is a free riding violation?

Freeriding is selling a stock you never paid for. Fidelity's example: you buy with no cash in the account, no payment arrives by settlement, and you sell the stock to cover the purchase. Schwab says the most common cause is a deposit that doesn't arrive after you've already traded with it.

This one is written into the rules. Under Regulation T, if a stock in a cash account is sold without being paid for in full, "the privilege of delaying payment beyond the trade date shall be withdrawn for 90 calendar days following the date of sale of the security." FINRA Rule 4210 also bars brokers from letting customers make a practice of paying for purchases by selling the same securities. Fidelity and Schwab can restrict an account after one freeriding violation in 12 months.

During the freeze you can still buy, but per the SEC, "the investor must fully pay for any purchase on the date of the trade." You can usually avoid the freeze by paying for the purchase in full, with money that doesn't come from selling it, before your broker's deadline. Ask your broker for that deadline as soon as you get a notice.

One naming trap: the SEC's cash account bulletin calls the step 3 sequence (sell, rebuy with the proceeds, sell again the same day) freeriding. FINRA and the brokers call it a good faith violation. Your account notices will use the broker's label.

What is a cash liquidation violation?

Fidelity: "A cash liquidation violation occurs when you buy securities and cover the cost of that purchase by selling other fully paid securities after the purchase date."

Example: on Monday you buy $2,500 of Stock A with no settled cash, planning to sell Stock B to pay for it. You sell Stock B on Tuesday. Stock A settles Tuesday, but Stock B's sale settles Wednesday, so on settlement day the purchase is unpaid.

How does a margin account change the picture?

It removes the cash-account violations. Schwab: "When trading in a margin account, you can use funds that have not yet settled and avoid cash violations without incurring interest". At Schwab, interest starts only when a trade exceeds your settled funds and that debit is carried overnight.

What you take on instead:

• Borrowing rules. You need $2,000 of equity to borrow, Reg T caps the loan at 50% of a purchase, and FINRA requires at least 25% maintenance. Many brokers set 30 to 40 percent.
• Margin calls without warning. FINRA says a firm "isn't required to notify you if your account equity drops below the minimum maintenance equity."
• Losses past zero. The SEC's example: a $50 stock falls to $15. Paid in full, you lose 70 percent. Bought half on margin, "you would lose more than 100 percent of your money" and still owe the broker.
• Short selling. It needs margin, because the broker lends you the shares.

What changed for day trading in 2026?

FINRA's day trade definition only ever covered trades "on the same day in a margin account," so cash accounts were never under the pattern day trader rule. On June 4, 2026, FINRA's intraday margin rules replaced it. At a switched broker there is no $25,000 minimum, and your margin account must hold its maintenance requirement through the whole trading day. Brokers that need more time may keep the old rule until October 20, 2027. Dates, deficit rules and which brokers have moved are in the PDT rule is gone.

Which account fits a long-only small-cap day trader?

Here's how I'd think it through if you trade the way I teach: buying stocks that are already moving, in the morning only. As I wrote in the Momentum Method, "I trade one thing, small-cap momentum, for two hours, from 9 to 11am."

Where a cash account fits. A morning-only window lines up with T+1. What you sell today is settled cash the next business day (normally Monday, for a Friday sale), so if your settled balance covers the trades you take before 11am, settlement is easier to manage. You don't need margin to buy stock. My rule for new traders also fits: "Start small, 5 to 100 shares, risking only a few dollars a trade."

Where it pinches. A second trade with the same money in one morning means waiting on settlement or risking a GFV.

Where margin fits. It solves that reuse problem. But small caps are where a broker may limit margin: FINRA notes firms may restrict margin on stocks "particularly susceptible to large daily price swings," and house maintenance can run well above 25%. Borrowed size on a fast small cap also means a bad fill or a halt can take you past your deposit.

My own view, from the PDT post: "A cash account teaches discipline and forces you to manage settled funds carefully. Move to margin when your results justify it." FINRA says frequent margin strategies "generally are not appropriate for investors with" limited resources, limited experience or low risk tolerance. Which trade-off fits is your call.

A checklist for choosing your account

• Which account type does your broker's application default to?
• Has your broker switched to FINRA's intraday margin rules?
• How many round trips do you take in a morning, and does your settled cash cover them?
• How many GFVs does your broker allow, and how long is the restriction?
• Can you see settled and unsettled cash on your trading screen?
• Does your broker allow margin on the volatile small caps you trade?
• Are you ready to lose more than you deposit? If not, borrowing can wait.

Frequently asked questions

Can I day trade with a cash account?

Yes. Cash accounts were never under the pattern day trader rule, and FINRA's 2026 intraday margin rule covers margin accounts only. Settled cash is your limit: each settled dollar covers one same-day round trip.

Is a cash or margin account better for day trading?

It depends on what you need. A cash account caps your loss at what you deposited and has no margin calls, but settlement limits how often you can reuse money. A margin account removes that limit and lets you borrow once you have $2,000 of equity, at the cost of interest, margin calls and losses that can exceed your deposit. FINRA says frequent margin strategies are generally not appropriate for investors with limited resources, limited experience or low risk tolerance. My own view: a cash account teaches discipline and forces you to manage settled funds carefully. Move to margin when your results justify it.

Is a good faith violation a big deal?

On its own, a single one brings no restriction at Fidelity, Schwab or Public. The count is what matters: at Fidelity and Schwab, three in 12 months can restrict you to settled cash for 90 days. Freeriding is more serious, because one can trigger the same restriction.

How long does a good faith violation last?

Brokers count violations over a 12-month period. A restriction typically lasts 90 days at Fidelity and Schwab, while Public's settled-funds restriction lasts at least 90 days and, in most cases, 12 months.

Can I have both a cash account and a margin account?

Yes. The SEC says brokerage firms may allow you to have both at the same time. Whether you can switch an existing account's type is up to your broker.

If I invest $5,000 and borrow $5,000 on margin, how much can I lose?

All of your $5,000 and more. Your $10,000 position is twice your money, so every 1% the stock falls costs you 2% of your own money, and a 50% fall wipes out your deposit. At FINRA's 25% maintenance minimum, a margin call comes after a fall of about one third (the position at about $6,667), and earlier at a 30% house requirement. The broker can sell you out without notice. Any fall past 50% is a debt you owe the broker, plus interest.
