Other than being able to borrow to invest, how is a margin trading account different from a cash account?
"Probably the most significant difference is the Damocles Sword hanging over your head, the Margin Call. In a nutshell, the lender (your broker) is going to require you to have a certain amount of assets in your account relative to your outstanding loan balance. The minimum ratio of liquid funds in the account to the loan is regulated in the US at 50% for the initial margin and 25% for maintenance margins. So here's where it gets sticky. If this ratio gets on the wrong side of the limits, the broker will force you to either add more assets/cash to your account t or immediately liquidate some of your holdings to remedy the situation. Assuming you don't have any/enough cash to fix the problem it can effectively force you to sell while your investments are in the tank and lock in a big loss. In fact, most margin agreements give the brokerage the right to sell your investments without your express consent in these situations. In this situation you might not even have the chance to pick which stock they sell. Source: Investopedia article, ""The Dreaded Margin Call"" Here's an example from the article: Let's say you   purchase $20,000 worth of securities   by borrowing $10,000 from your   brokerage and paying $10,000 yourself.   If the market value of the securities   drops to $15,000, the equity in your   account falls to $5,000 ($15,000 -   $10,000 = $5,000). Assuming a   maintenance requirement of 25%, you   must have $3,750 in equity in your   account (25% of $15,000 = $3,750).   Thus, you're fine in this situation as   the $5,000 worth of equity in your   account is greater than the   maintenance margin of $3,750. But   let's assume the maintenance   requirement of your brokerage is 40%   instead of 25%. In this case, your   equity of $5,000 is less than the   maintenance margin of $6,000 (40% of   $15,000 = $6,000). As a result, the   brokerage may issue you a margin call.

Without margin accounts this is the time you close the trade + 3 business days for clearing. In practice this means 4-5 days if there is a weekend or holiday involved between those 3 business days. This ties up your capital for an unfavorable amount of time, where as a margin account lets you continue to use the capital over and over again for more opportunities. You CANNOT sell to open a position in cash accounts. This means no short selling. This means no covered calls or spreads and MANY other strategies. These are the real differences you'll notice in a margin account vs a cash account.  Then there are the myriad of regulations that dictate how much cash you should keep in your account for any margin position. "In summary: In long form: Spreads and shorts are not allowed in cash accounts, except for covered options. Brokers will allow clients to roll option positions in a single transaction, which look like spreads, but these are not actually ""sell to open"" transactions. ""Sell to open"" is forbidden in cash accounts. Short positions from closing the long half of a covered trade are verboten. Day-trading is allowed in both margin and cash accounts. However, ""pattern day-trading"" only applies to margin accounts, and requires a minimum account balance of $25,000. Cash accounts are free to buy and sell the same security on the same day over and over, provided that there is sufficient buying power to pay for opening a new position. Since proceeds are held for both stock and option sales in a cash account, that means buying power available at the start of the day will drop with each purchase and not rise again until settlement. Unsettled funds are available immediately within margin accounts, without restriction. In cash accounts, using unsettled funds to purchase securities will require you to hold the new position until funds settle -- otherwise your account will be blocked for ""free-riding"". Legally, you can buy securities in a cash account without available cash on deposit with the broker, but most brokers don't allow this, and some will aggressively liquidate any position that you are somehow able to enter for which you didn't have available cash already on deposit. In a margin account, margin can help gloss over the few days between purchase and deposit, allowing you to be somewhat more aggressive in investing funds. A margin account will allow you to make an investment if you feel the opportunity is right before requiring you to deposit the funds. See a great opportunity? With sufficient margin, you can open the trade immediately and then run to the bank to deposit funds, rather than being stuck waiting for funds to be credited to your account. Margin accounts might show up on your credit report. The possibility of losing more than you invested, having positions liquidated when you least expect it, your broker doing possibly stupid things in order to close out an over-margined account, and other consequences are all very serious risks of margin accounts. Although you mentioned awareness of this issue, any answer is not complete with mentioning those risks." Two more esoteric differences, related to the same cause... When you have an outstanding debit balance in a margin the broker may lend out your securities to short sellers.  (They may well be able to lend them out even if there's no debit balance -- check your account agreement and relevant regulations).   You'll never know this (there's no indication in your account of it) unless you ask, and maybe not even then. If the securities pay out dividends while lent out, you don't get the dividends (directly).  The dividends go to the person who bought them from the short-seller.  The short-seller has to pay the dividend amount to his broker who pays them to your broker who pays them to you.  If the dividends that were paid out by the security were qualified dividends (15% max rate) the qualified-ness goes to the person who bought the security from the short-seller.  What you received weren't dividends at all, but a payment-in-lieu of dividends and qualified dividend treatment isn't available for them.   Some (many?  all?) brokers will pay you a gross-up payment to compensate you for the extra tax you had to pay due to your qualified dividends on that security not actually being qualified. A similar thing happens if there's a shareholder vote.  If the stock was lent out on the record date to establish voting eligibility, the person eligible to vote is the person who bought them from the short-seller, not you.  So if for some reason you really want/need to vote in a shareholder vote, call your broker and ask them to journal the shares in question over to the cash side of your account before the record date for determining voting eligibility.
Disregarding leverage and things alike, I would like to know what's the difference between opening a position in Forex on a pair through a broker, for example, and effectively buy some currency in a traditional bank-to-bank transition The forex account may pay or charge you interest whereas converting your currency directly will not.  Disregarding leverage, the difference would be interest. "None of the previous answers (which are all good) mention margin accounts (loans from your broker).  You may also have heard them described as ""leverage"".  It may seem odd to mention this rather narrow form of debt here, but it's important because overuse of leverage has played a large part in pretty much every financial crisis you can think of (including the most recent one).  As the Investopedia definitions indicate, leverage magnifies gains, but also magnifies losses. I consider margin/leverage to be ""bad"" debt." The major drawback to borrowing to invest (i.e. using leverage) is that your return on investment must be high enough to overcome the cost of finance. The average return on the S&P 500 is about 9.8% (from CNBC) a typical unsecured personal loan will have an interest rate of around 18-36% APR (from NerdWallet). This means that on average you will be paying more interest than you are receiving in returns so are losing money on the margin investment. Sometimes the S&P falls and over those periods you would be paying out interest having lost money so will have a negative return! You may have better credit and so be able to get a lower rate but I don't know your loan terms currently. Secured loans, such as remortgaging your house, will have lower costs but come with more life changing risks. The above assumes that you are getting financing by directly borrowing money, however, it is also possible to trade on margin. This is where you post a proportion of the value that you wish to trade with as collateral against a loan to buy the security. This form of finance is normally used by day traders and other short term holders of stocks. Although the financing costs here are low (I am not charged an interest rate on intraday margin trading) there are very high costs if you exceed the term of the loan. An example is that I am charged a fee if I hold a position overnight and my profits and losses are crystallised at that time. If I am in a losing position at that time the crystallisation process and fee can result in not having enough margin to recover the position and the loss of a potentially profit making position. Additionally if the amount of collateral cash (margin) posted is insufficient to cover the expected losses as calculated by your broker they will initiate a margin call asking for more collateral money. If you do not (or cannot) post this extra margin your losing position will be cashed out and you will take as a loss the total loss at that time. Since the market can change very rapidly, such as in a flash crash, this can result in your losing more money than you had in the first place. As this is essentially a loan you can be bankrupted by this. Overall using leverage to invest magnifies your potential profits but it also magnifies your potential losses. In many cases this magnification could be sufficient to lose you more money than you had originally invested. In addition to magnification you need to consider the cost of finance and that your return over the course of the loan needs to be higher than your cost of finance as well as inflation and other opportunity costs of capital. The S&P 500 is a relatively low volatility market in general so is unlikely to return losses in any given period that will mean that leverage of 1.25 times will take you into losses beyond your own capital investment but it is not impossible. The low level of risk automatically means that your returns are lower and so your cost of capital is likely to be a large proportion of your returns and your returns may not completely cover the cost of capital even when you are making money. The key thing if you are going to trade or invest on leverage is to understand the terms and costs of your leverage and discount them from any returns that you receive before declaring to yourself that you are profitable. It is even more important than usual to know how your positions are doing and whether you are covering your cost of capital when using leverage. It is also very important to know the terms of your leverage in detail, especially what will happen when and if your credit runs out for whatever reason be it the end of the financing period (the length of the loan) or your leverage ratio gets too high. You should also be aware of the costs of closing out the loan early should you need to do so and how to factor that into your investing decisions. A checking account is instant access. It can be tapped via check or debit card.  A savings account is supposed to be used to accumulate cash for a goal that is is longer term or for an emergency.  Many people need to separate these funds into different accounts to be able to know if they are overspending or falling short on their savings. In the United States the Federal Reserve also looks at these accounts differently. Money in a checking account generally can't be used to fund loans, money in a savings account can be used as a source of loans by the bank. An even greater percentage of funds in longer term accounts can be used to fund loans. This includes Certificates of Deposit, and retirement accounts. "The broker will charge borrowing fees and sometimes a charge called ""hard-to-borrow fee"". Other than that you will earn interest on the cash you get from selling the stocks, but you will have to pay dividends.  This is because someone else (the party you sold the stocks off to) will now get the dividends and the party who lent you the stocks will miss out on these, that's why you have to remunerate them. The type of account you need is entirely up to your broker (and besides, it depends on what a 'normal' account for you is, you should at least mention your country or your broker)." The T+3 settlement date only affects cash accounts.  In a cash account, you need to wait until the T+3 settlement date for your funds to be available to make your next trade.  But if you convert your cash account into a margin account, then you do not need to wait until the T+3 settlement date for your next trade - your broker will allow you to make another trade immediately. "The margin rules are also more complicated.  A simple buy on a non-margin account will never run into margin rules and you can just wait out any dips if you have confidence the stock will recover.  A ""simple"" short sell might get you a call from your broker that you have a margin call, and you can't wait it out without putting more money in.  Personally I have trouble keeping the short sale margin rules straight in my head, at least compared to a long sale. I got in way over my head shorting AMZN once, and lost a lot of money because I thought it was overvalued at the time, but it just kept going up and I wanted it to go down.   I've never gotten stuck like that on a long position." That is the maintenance margin required for that position.  Whenever you trade using your margin account, you must (by law, and also separately often by stricter policies from the brokerage) have a certain percentage of equity - at least 25%, often higher.  That protects the brokerage from significant losses if your position drops in value significantly (hopefully preventing the brokerage from failing outright in the event of a major collapse).  If the amount of equity falls below the maintenance requirement, you will have a margin call and be required to put some cash (or equity) into the account to maintain that level. See Maintenance Margin definition on Investopedia for more information. According to Regulation T, you can make as many day trade (round trip) stock purchases using a cash account as long as you have the funds to cover each and every round trip sale. However, the funds generated from the sales cannot be used again to purchase new stocks until the settlement period (T-2 or T-3) is over. For example, say you have $10000 dollars in your cash account and no securities. You buy 1000 shares of XYZ stock in the morning at one dollar per share and you sell the stock 30 minutes later because it went up say by 50 cents. According to Regulation T, you cannot use the money generated from the sale of your 1000 shares until after the settlement date. However, you can use the remaining $9000 dollars in your account to execute other trades just as the first trade. You can do this as many times as you want as long as you have funds available to pay for the transaction the same day it's executed. The only thing to worry about and that isn't clear, is, what happens if you perform this action more than 3 times in a week? Does it mean that your cash account now becomes a margin account subject to margin account rules because you executed more than three round trip trades in a five day rolling period? hmmm. I think it's because in both cases, you must pay for it up front, before the positions are closed out. You own nothing except the right to buy the stock re: the call, and the obligation to buy the stock re: the short.  You buy a call, but must borrow the stock, for which you must put some margin collateral and there is a cost to borrow. You pay for that, of course.  I wouldn't call it lending though. In general, investors with a long period of time until they would need to withdraw the cash are best off holding mostly equities.  While the dividends that equities would return are less than the interest you would get in peer-to-peer lending, over long periods of time not only do you get the dividends from equity investment but the value of the stock will grow faster than  interest on loans. The higher returns from stocks, however, comes with more risk of big downturns.  Many people pull their investments out of stocks right after crashes which really hurts their long term returns.  So, in order to get the benefit of investing in stocks you need to be strong enough to continue to hold the stocks through the crash and into the recovery. As for which stocks to invest in, generally it is best to invest in low-fee index funds/etfs where you own a broad collection of stocks so that if (when) any one stock goes bust that your portfolio does not take much damage.  Try to own both international and domestic stocks to get good diversification.  The consensus recommends adding just a little bit of REITs and bonds to your investments, but for someone at 25 it might not be worth it yet. Warren Buffett had some good thoughts on index investing. I personally spoke with a Questrade agent about my question. To make a long story short: in a margin account, you are automatically issued a loan when buying U.S. stock with a Canadian money. Whereas, in a registered account (e.g. RRSP), the amount is converted on your behalf to cover the debit balance. Me: What happens if I open an account and I place an order for U.S. stocks   with Canadian money? Is the amount converted at the time of transfer?   How does that work? Agent: In a margin account, you are automatically issued a loan   for a currency you do not have, however, if you have enough buying   power, it will go through. The interest on the overnight balance is   calculated daily and is charged on a monthly basis. We do not convert   funds automatically in a margin account because you can have a debit   cash balance. Agent: In a registered account, the Canada Revenue Agency does not allow a debit   balance and therefore, we must convert your funds on your behalf   to cover the debit balance if possible. We convert automatically   overnight for a registered account. Agent: For example, if you buy U.S. equity you will need USD to buy it,   and if you only have CAD, we will loan you USD to cover for that   transaction. For example, if you had only $100 CAD and then wanted to   buy U.S. stock worth $100 USD, then we will loan you $100 USD to   purchase the stock. In a margin account we will not convert the funds   automatically. Therefore, you will remain to have a $100 CAD credit and   a $100 USD debit balance (or a loan) in your account. Me: I see, it means the longer I keep the stock, the higher interest   will be? Agent: Well, yes, however, in a registered account there will be not   be any interest since we convert your funds, but in a margin account, there will   be interest until the debit balance is covered, or you can manually   convert your funds by contacting us. "Lending of shares happens in the background. Those who have lent them out are not aware that they have been lent out, nor when they are returned. The borrowers have to pay any dividends to the lenders and in the end the borrowers get their stock back. If you read the fine print on the account agreement for a margin account, you will see that you have given the brokerage the permission to silently loan your stocks out.  Since the lending has no financial impact on your portfolio, there's no particular reason to know and no particular protection required.  Actually, brokers typically don't bother going through the work of finding an actual stock to borrow.  As long as lots of their customers have stocks to lend and not that many people have sold short, they just assume there is no problem and keep track of how many are long and short without designating which stocks are borrowed from whom. When a stock becomes hard to borrow because of liquidity issues or because many people are shorting it, the brokerage will actually start locating individual shares to borrow, which is a more time-consuming and costly procedure.  Usually this involves the short seller actually talking to the broker on the phone rather than just clicking ""sell.""" In the U.S. it is typical that a stock brokerage account can be set up to buy stock with up to half the cost being borrowed from the broker.  This is called a margin account.  The stock purchased must remain in the account until sold (or the loan is paid off), as it serves as built-in collateral for the loan.  If the market price for the stock goes down too much, you will be required to add money, or the stock will be sold to cover the loan. See this question for some more information. They will make money from brokerage as usual and also from the interest they charge you for lending you the money for you to buy your shares on margin. In other words you will be paying interest on the $30,000 you borrowed from your broker. Also, as per Chris's comment, if you are shorting securities through your margin account, your broker would charge you a fee for lending you the securities to short.
