Why can Robin Hood offer trading without commissions?
It isn't the first initiative (see link below) and maybe this one will stick around.  Time will be a good test.   Here is an article on it.... http://www.investopedia.com/articles/active-trading/020515/how-robinhood-makes-money.asp  They plan to make money off unused balances - so they hope to get the masses signed up using the 0$ fees.  Also, no type of advanced trading, just limit and market orders.   Think of it this way - even if someone puts in 100$ and buys a stock at 88$...that 12$ sits there.  Multiply that by say....200,000 accounts and then do a basic 3% return on that.   Also, they plan for margin accounts in the future.   Time will tell....  sort of like I use Acorn right now (but it charges a fee to invest - a slightly higher than normal one). I signed up for fun and am just letting it ride. "All discount brokers offer a commission structure that is based on the average kind of order that their target audience will make. Different brokers advertise to different target audiences. They could all have a lot lower commissions than they do. The maximum commission price for the order ticket is set at $99 by the industry securities regulators. When discount brokers came along and started offering $2 - $9.99 trades, it was simply because these new companies could be competitive in a place where incumbents were overcharging. The same exists with Robinhood. The market landscape and costs have changed over the last decade with regulation NMS, and other brokerage firms never needed to update drastically because they could continue making a lot on commissions with nobody questioning it. The conclusion being that other brokers can also charge a lot less, despite their other overhead costs. Robinhood, like other brokerage firms (and anyone else trading directly with the exchanges), are paid by the exchanges for adding liquidity. Not only are many trades placed with no commission for the broker, they actually earn money for placing the trade. If Robinhood was doing you any favors, they would be paying you. But nobody questions free commissions so they don't. Robinhood, like other brokerage firms, sells your trading data to the highest bidder. This is called ""payment for order flow"", these subscribers see your order on the internet in route to the exhange, and before your order gets to the exchange, the subscriber sends a different order to the exchange so they either get filled before you do (analogous to front running, but different enough to not be illegal) or they alter the price of the thing you wanted to buy or sell so that you have to get a worse price. These subscribers have faster computers and faster internet access than other market participants, so are able to do this so quickly. They are also burning a lot of venture capital like all startups. You shouldn't place too much faith in the idea they are making [enough] money. They also have plans to earn interest off of balances in a variety of ways and offer more options at a price (like margin accounts)." Robinhood does offer premium products that they charge for-I suspect we will see more of that in the future. They do not change the bid/ask spread as some have said because they have to give you the NBBO. They make money off you by increasing the spread you buy and sell your stocks through them.  So for example, if the normal spread for a stock was $10.00 for a buy and $10.02 for a sell, they might have a spread of $9.98 for the buy and $10.02 for the sell. So for an order of 1000 shares (approx. $10000) they would make $0.02 per share which would equal $20.00. They mostly make money off of the spread between your order and the spread of the buy and sell currently in the market. As others have previously explained, their buy/sell spreads are a little lacklustre.
"This information is clearly ""material"" (large impact) and ""non-public"" according to the statement of the problem.  Also, decisions like United States v. Carpenter make it clear that you do not need to be a member of the company to do illegal insider trading on its stock. Importantly though, stackexchange is not a place for legal advice and this answer should not be construed as such.  Legal/compliance at Company A would be a good place to start asking questions." You can't sell options if you don't have margin account (except covered call).  You can't trade futures if you don't have margin account.  Everything is immediate when you have margin account. (Including stocks) Margin account is not subject to freeriding rules, but is subject to Pattern Day Trader rules. It comes down to the practical value of paying dividends. The investor can continually receive a stream of income without selling shares of the stock. If the stock did not pay a dividend and wanted continual income, the investor would have to continually sell shares to gain this stream of income, incurring transaction costs and increased time and effort involved with making these transactions. Here's how this works in the United States. There's no law regarding your behavior in this matter and you haven't broken any laws. But your broker-dealer has a law that they must follow. It's documented here: The issue is if you buy stock before your sell has settled (before you've received cash) then you're creating money where before none existed (even though it is just for a day or two). The government fears that this excess will cause undue speculation in the security markets. The SEC calls this practice freeriding, because you're spending money you have not yet received. In summary: your broker is not allowed to loan money to an account than is not set-up for loans; it must be a margin account. People with margin account are able to day-trade because they have the ability to use margin (borrow money). Margin Accounts are subject to Pattern Daytrading Rules. The Rules are set forth by FINRA (The Financial Industry Reporting Authority) and are here: You must understand that: So, if you -- the prospective buyer -- are in Waukegan, do you take the train all the way to New York City just to buy 100 shares of stock?  No.  That would be absurdly expensive.  So, you hire an agent in NYC who will broker a deal for you in the exchange. Fast forward 100 years, to the time when instant communications is available.  Why do we now still need brokerages, when the Exchanges could set up web sites and let you do the trading? The answer is that the Exchanges don't want to have to develop the accounting systems to manage the transactions of hundreds of thousands of small traders, when existing brokerage firms already have those computerized processes in place and are opening their own web sites. Thus, in 2017 we have brokerage firms because of history. "I am not familiar with this broker, but I believe this is what is going on: When entering combination orders (in this case the purchase of stocks and the writing of a call), it does not make sense to set a limit price on the two ""legs"" of the order separately. In that case it may be possible that one order gets executed, but the other not, for example. Instead you can specify the total amount you are willing to pay (net debit) or receive (net credit) per item. For this particular choice of a ""buy and write"" strategy, a net credit does not make sense as JoeTaxpayer has explained. Hence if you would choose this option, the order would never get executed. For some combinations of options it does make sense however. It is perhaps also good to see where the max gain numbers come from. In the first case, the gain would be maximal if the stock rises to the strike of the call or higher. In that case you would be payed out $2,50 * 100 = $250, but you have paid $1,41*100 for the combination, hence this leaves a profit of $109 (disregarding transaction fees). In the other case you would have been paid $1,41 for the position. Hence in that case the total profit would be ($1,41+$2,50)*100 = $391. But as said, such an order would not be executed. By the way, note that in your screenshot the bid is at 0, so writing a call would not earn you anything at all." "Am I wrong?  Yes. The exchanges are most definitely not ""good ole boys clubs"". They provide a service (a huge, liquid and very fast market), and they want to be paid for it. Additionally, since direct participants in their system can cause serious and expensive disruptions, they allow only organizations that know what they're doing and can pay for any damages the cause. Is there a way to invest without an intermediary? Certainly, but if you have to ask this question, it's the last thing you should do. Typically such offers are only superior to people who have large investments sums and know what they're doing - as an inexperienced investor, chances are that you'll end up losing everything to some fraudster. Honestly, large exchanges have become so cheap (e.g. XETRA costs 2.52 EUR + 0.0504% per trade) that if you're actually investing, then exchange fees are completely irrelevant. The only exception may be if you want to use a dollar-cost averaging strategy and don't have a lot of cash every month - fixed fees can be significant then. Many banks offer investments plans that cover this case." I don't believe from reading the responses above that Questrade is doing anything 'original' or 'different' much less 'bad'. In RRSPs you are not allowed to go into debt. So the costs of all trades must be covered.  If there is not enough USD to pay the bill then enough CAD is converted to do so.  What else would anyone expect? How margin accounts work depends on whether the broker sets up different accounts for different currencies. Some do, some don't.  The whole point of using 'margin' is to buy securities when you don't have the cash to cover the cost.  The result is a 'short' position in the cash.  Short positions accrue interest expense which is added to the balance once a month.  Every broker does this. If you buy a US stock in a USD account without the cash to cover it, you will end up with USD margin debt.  If you buy US stock in an account that co-mingles both USD and CAD assets and cash, then there will be options during the trade asking if you want to settle in USD or CAD.  If you settle in CAD then obviously the broker will convert the necessary CAD funds to pay for it.  If you settle in US funds, but there is no USD cash in the account, then again, you have created a short position in USD. "This is a complicated subject, because professional traders don't rely on brokers for stock quotes.  They have access to market data using Level II terminals, which show them all of the prices (buy and sell) for a given stock.   Every publicly traded stock (at least in the U.S.) relies on firms called ""market makers"".  Market makers are the ones who ultimately actually buy and sell the shares of companies, making their money on the difference between what they bought the stock at and what they can sell it for.  Sometimes those margins can be in hundreds of a cent per share, but if you trade enough shares...well, it adds up. The most widely traded stocks (Apple, Microsoft, BP, etc) may have hundreds of market makers who are willing to handle share trades.  Each market maker sets their own price on what they'll pay (the ""bid"") to buy someone's stock who wants to sell and what they'll sell (the ""ask"") that share for to someone who wants to buy it.   When a market maker wants to be competitive, he may price his bid/ask pretty aggressively, because automated trading systems are designed to seek out the best bid/ask prices for their trade executions.  As such, you might get a huge chunk of market makers in a popular stock to all set their prices almost identically to one another.  Other market makers who aren't as enthusiastic will set less competitive prices, so they don't get much (maybe no) business.  In any case, what you see when you pull up a stock quote is called the ""best bid/ask"" price.  In other words, you're seeing the highest price a market maker will pay to buy that stock, and the lowest price that a market maker will sell that stock.  You may get a best bid from one market maker and a best ask from a different one.  In any case, consumers must be given best bid/ask prices. Market makers actually control the prices of shares.  They can see what's out there in terms of what people want to buy or sell, and they modify their prices accordingly.  If they see a bunch of sell orders coming into the system, they'll start dropping prices, and if people are in a buying mood then they'll raise prices. Market makers can actually ignore requests for trades (whether buy or sell) if they choose to, and sometimes they do, which is why a limit order (a request to buy/sell a stock at a specific price, regardless of its current actual price) that someone places may go unfilled and die at the end of the trading session.  No market maker is willing to fill the order. Nowadays, these systems are largely automated, so they operate according to complex rules defined by their owners.  Very few trades actually involve human intervention, because people can't digest the information at a fast enough pace to keep up with automated platforms. So that's the basics of how share prices work.  I hope this answered your question without being too confusing! Good luck!" Will there be a scenario in which I want to sell, but nobody wants to buy from me and I'm stuck at the brokerage website? Similarly, if nobody wants to sell their stocks, I will not be able to buy at all? Yes, that is entirely possible. Investopedia has a section in their article about currency trading that states: The FX market does not have commissions. Unlike exchange-based markets, FX is a principals-only market. FX firms are dealers, not brokers. This is a critical distinction that all investors must understand. Unlike brokers, dealers assume market risk by serving as a counterparty to the investor's trade. They do not charge commission; instead, they make their money through the bid-ask spread. Principals-only means that the only parties to a transaction are agents who actively bear risk by taking one side of the transaction.  There are forex brokers who charge what's called a commission, based on the spread. Investopedia has another article about the commission structure in the forex market that states: There are three forms of commission used by brokers in forex. Some firms offer a fixed spread, others offer a variable spread and still others charge a commission based on a percentage of the spread.  So yes, there are forex brokers who charge a commission, but this paragraph is saying mostly the same thing as the first paragraph. The brokers make their money through the bid-ask spread; how they do so varies, and sometimes they call this charge a commission, sometimes they don't. All of the information above differs from the stock markets, however, in which  The broker takes the order to an exchange and attempts to execute it as per the customer's instructions. For providing this service, the broker is paid a commission when the customer buys and sells the tradable instrument. The broker isn't taking a side in the trade, so he's not making money on the spread. He's performing the service of taking the order to an exchange an attempting to execute it, and for that, he charges a commission. This investment strategy may have tax advantages. In some countries, income received from dividends is taxed as income, whereas profits on share trades are capital gains. If you have already exceeded your tax-free income limit for the year, but not your capital gains tax allowance, it may be preferable to make a dealing profit rather than an investment income. These arrangements are called a bed-and-breakfast. "You can certainly try to do this, but it's risky and very expensive. Consider a simplified example. You buy 1000 shares of ABC at $1.00 each, with the intention of selling them all when the price reaches $1.01. Rinse and repeat, right? You might think the example above will net you a tidy $10 profit. But you have to factor in trade commissions. Most brokerages are going to charge you per trade. Fidelity for example, want $4.95 per trade; that's for both the buying and the selling. So your 1000 shares actually cost you $1004.95, and then when you sell them for $1.01 each, they take their $4.95 fee again, leaving you with a measly $1.10 in profit. Meanwhile, your entire $1000 stake was at risk of never making ANY profit - you may have been unlucky enough to buy at the stock's peak price before a slow (or even fast) decline towards eventual bankruptcy.  The other problem with this is that you need a stock that is both stable and volatile at the same time. You need the volatility to ensure the price keeps swinging between your buy and sell thresholds, over and over again. You need stability to ensure it doesn't move well away from those thresholds altogether. If it doesn't have this weird stable-volatility thing, then you are shooting yourself in the foot by not holding the stock for longer: why sell for $1.01 if it goes up to $1.10 ten minutes later? Why buy for $1.00 when it keeps dropping to $0.95 ten minutes later? Your strategy means you are always taking the smallest possible profit, for the same amount of risk. Another method might be to only trade each stock once, and hope that you never pick a loser. Perhaps look for something that has been steadily climbing in price, buy, make your tiny profit, then move on to the next company. However you still have the risk of buying something at it's peak price and being in for an awfully long wait before you can cash out (if ever). And if all that wasn't enough to put you off, brokerages have special rules for ""frequent traders"" that just make it all the more complicated. Not worth the hassle IMO." It's a good answer. I was alluding to cryptocurrency such as bitcoin which was a pretty genius invention (blockchain and mining) to solve the honesty problem (counterparty risk) you outlined when there's no trusted middleman to help keep people honest. Sounds like a dodgy cat though! Yes, you would have to report the gain. It is not relevant that you traded the stock previously, you still made a profit on the trade-at-hand. Imagine if for some reason this type of trade were exempt. Investors could follow the short term swings of volatile stocks completely tax-free.
