Trading with unsettled cash is allowed in most situations: your broker will let you buy a new position using the proceeds of a sale that hasn’t officially cleared yet. The trouble starts if you then sell that new position, or otherwise close the loop, before the original sale settles. Under the T+1 settlement cycle, three specific cash-account violations can restrict your account for 90 days, and one of them needs only a single occurrence to do it.
What T+1 Settlement Actually Means
A trade executes on your screen in seconds, but the actual exchange of cash and shares takes an extra business day. SEC Rule 15c6-1 requires most securities transactions to settle no later than the first business day after the trade date, written as T+1.1eCFR. 17 CFR 240.15c6-1 – Settlement Cycle Sell shares on Tuesday, and the cash is officially yours Wednesday. Until then, your platform shows the proceeds as “unsettled” or “available to trade,” not “settled.”
Stocks, bonds, ETFs, municipal securities, most mutual funds, and options all run on T+1.2FINRA. Understanding Settlement Cycles: What Does T+1 Mean for You For everyday retail trading, assume everything you buy or sell settles the next business day.
Buying With Unsettled Funds Is Fine
This is where people get confused. Buying with unsettled cash is not a violation. Your broker shows an “available to trade” balance that includes the proceeds of recent sales, and you can use that balance to open a new position right away. The broker is extending a short-term credit against the incoming funds, which Regulation T’s cash-account rules permit as long as you act in good faith.3eCFR. 12 CFR 220.8 – Cash Account
The problems start when you sell that new position before the original proceeds settle. Every cash-account violation below traces back to that single pattern. Buying is the easy part. Selling too soon is what creates the record.
Good Faith Violations
A good faith violation happens when you buy a security with unsettled funds and then sell that security before the funds you used to buy it have settled. Regulation T requires that when a broker lets you purchase in a cash account on short-term credit, you intend to pay in full before selling.3eCFR. 12 CFR 220.8 – Cash Account Selling first breaks that assumption.
A worked example: Monday morning you sell Stock A for $3,000. That afternoon you use the unsettled proceeds to buy Stock B. Still fine. If you then sell Stock B any time before Stock A’s proceeds settle on Tuesday, you’ve committed a good faith violation. You effectively round-tripped a trade on money that didn’t exist yet.
Most brokers allow three good faith violations in a rolling 12-month period before they restrict the account. The three-strike threshold is an industry-standard practice rather than a number mandated by federal regulation; some firms warn you earlier, and policies vary. After the third violation, the typical consequence is a 90-day restriction that forces you to have fully settled cash in the account before any buy order.
Cash Liquidation Violations
This one catches people who think they’re being careful. A cash liquidation violation occurs when you buy a security and then sell a different, fully paid position after the purchase date to cover the cost, but the covering sale doesn’t settle in time.
Suppose you buy $4,000 of Stock X on Monday with no settled cash in the account, planning to sell Stock Y (which you already own) to cover it. You sell Stock Y on Tuesday. Stock X’s purchase settles Tuesday. Stock Y’s sale doesn’t settle until Wednesday. On settlement day for your purchase, the money isn’t there yet. That gap is the violation.
The consequences mirror good faith violations: three in 12 months typically triggers a 90-day settled-cash-only restriction. The fix is simple in theory and easy to forget: if you need to sell an existing position to fund a new purchase, sell first and wait for settlement before buying.
Free Riding Is the Serious One
Free riding is the most severe cash-account violation. It happens when you buy a security and then sell it to generate the funds needed to pay for the original purchase. You never had the money, and the broker’s capital carried the trade.4Investor.gov. Freeriding
Classic case: your cash account has a $0 settled balance. You buy $5,000 of shares, watch them rise to $5,500, and sell them the same day. The sale proceeds funded the purchase. No money of yours was ever at risk.
Unlike the other two, free riding triggers the 90-day freeze on a single occurrence. Regulation T requires brokers to withdraw the privilege of delayed payment for 90 calendar days following the sale of a security that was never paid for in full.5eCFR. 12 CFR Part 220 – Credit by Brokers and Dealers (Regulation T) You can still buy during the freeze, but only with the full purchase price in settled cash before the order is placed.4Investor.gov. Freeriding Repeated free riding can lead to permanent account closure.
What a 90-Day Restriction Looks Like
Once the restriction hits, every purchase needs fully settled funds sitting in the account before you click buy. For active traders, that effectively slows everything by a business day.
The clock runs 90 calendar days from the date of the triggering violation. During that window you have a few paths. The simplest is to wait it out and trade only with settled cash. Some brokers offer a one-time courtesy reinstatement if you call and ask, though nothing guarantees it. You can open a margin account, which bypasses most settlement-timing issues by design. Transferring to a new brokerage will not reliably reset your violation history, because the new firm can request your account records.
Habits That Keep You Clean
Every cash-account violation reduces to the same mistake: selling something before the money backing it has settled. A few habits remove the risk:
- Watch settled cash and “available to trade” as separate numbers. Most platforms show both. They are not the same, and the difference is where violations live.
- Wait one business day after buying before selling. If you bought on Monday with unsettled funds, those funds settle Tuesday. Selling Tuesday or later keeps you clean.
- Sell before you buy when funding a new position from an existing one. Reverse that order and you’ve set up a cash liquidation violation.
- Don’t buy anything you can’t pay for with money already in the account. That is the free-riding rule in one sentence. If your settled cash is zero, don’t buy.
Margin Accounts Sidestep the Problem
Margin accounts work under a different structure, and good faith and cash liquidation violations essentially don’t apply. The brokerage extends a line of credit governed by Regulation T and FINRA Rule 4210.6FINRA. Margin Regulation Purchases draw on that credit rather than on specific settled proceeds, so the buy-then-sell timing that trips cash accounts isn’t an issue.
The trade-offs are real. Regulation T limits the broker to lending up to 50 percent of the purchase price of stocks, so you need to put up at least half yourself.6FINRA. Margin Regulation FINRA Rule 4210 requires a minimum equity balance of $2,000 and ongoing maintenance margin of at least 25 percent of the current market value of your holdings.7FINRA. FINRA Rule 4210 – Margin Requirements Drop below the maintenance level and you’ll face a margin call. You’re also borrowing money and paying interest on it, and a sharp decline can trigger forced sales.
One further boundary: if you trade frequently in a margin account, FINRA’s pattern day trader rule kicks in. Four or more day trades within five business days (and more than six percent of your trading activity in that period) classifies you as a pattern day trader, and you must then maintain at least $25,000 in equity in the account at all times.8FINRA. Day Trading If part of your reason for staying in a cash account is to avoid that threshold, the settlement-timing rules above are the price of admission.
Taxes Follow the Trade Date, Not Settlement
Unsettled funds create a reporting trap at year-end. The IRS uses the trade date, not the settlement date, for capital gains and losses. Your holding period begins the day after you buy and ends on the day you sell, regardless of when cash actually settles.9Internal Revenue Service. Publication 550 – Investment Income and Expenses
Sell a stock on December 31 and the gain or loss belongs to that year’s tax return, even though the proceeds won’t settle until early January. A stock bought on December 31 starts its holding period on January 1, even though you haven’t technically paid for it yet. The settlement timeline governs your account; it does not govern the tax year.
