How to trade at Athens Stock Exchange (ASE)
Saxo Bank offers direct access to Athens Stock Exchange. Interactive Brokers is your next best bet, and as you probably already noticed, they do not have a free platform. They are open to US and non-US citizens. Although they do not currently have direct exposure to individual companies on the Athens Stock Exchange, the various european exchanges they do provide direct market access for will give a lot of exposure. There are a few Greek companies that trade on non-Greek stock exchanges, if you want exposure. There are also Greek ETFs which bundle several companies together or try to replicate Greek company indices.
You haven't looked very far if you didn't find index tracking exchange-traded funds (ETFs) on the Toronto Stock Exchange. There are at least a half dozen major exchange-traded fund families that I'm aware of, including Canadian-listed offerings from some of the larger ETF providers from the U.S. The Toronto Stock Exchange (TSX) maintains a list of ETF providers that have products listed on the TSX. "In the US there is only one stock market (ignoring penny stocks) and handfuls of different exchanges behind it.  NYSE and NASDAQ are two different exchanges, but all the products you can buy on one can also be bought on the other; i.e. they are all the same market.  So a US equities broker cannot possibly restrict access to any ""markets"" in the US because there is only one. (Interestingly, it is commonplace for US equity brokers to cheat their customers by using only exchanges where they -- the brokers -- get the best deals, even if it means your order is not executed as quickly or cheaply as possible.  This is called payment for order flow and unfortunately will probably take an Act of Congress to stop.) Some very large brokers will have trading access to popular equity markets in other countries (Toronto Stock Exchange, Mexico Stock Exchange, London Stock Exchange) and can support your trades there.  However, at many brokers or in less popular foreign markets this is usually not the case; to trade in the average foreign country you typically must open an account with a broker in that country." "When we say ""stock market,"" we are usually thinking of the publicly traded stocks, such as the New York Stock Exchange or the NASDAQ. Shares of individual products do not go on these exchanges, only large corporations.  You won't see a stock ticker symbol for The Force Awakens or for the iPhone 6s Plus.  The reason for this is that when investors buy a stock, they are looking for something that will grow in value theoretically forever. Individual products usually have a limited lifespan. Your movie will (hopefully) generate revenue when it comes out, but after a while sales will slow down after people have seen it. If someone bought a share of stock in a movie on the stock market, they have to realize that eventually the movie will stop making money, and their share of stock won't be worth anything anymore. Instead, people invest in companies that have the potential to make new products, such as Disney or Apple.  So if you were envisioning seeing the ticker symbol of your movie going across the screen on CNBC, sorry, that's not going to happen.  However, you could theoretically sell shares to individual investors for a percentage of the profit. You figure out how much money you need to create the movie, and estimate how much profit you think the movie will earn. Then you find an investor (or group of investors) that is willing to give you the money you need in exchange for a percentage of the profit. Unlike a stock market investor, these investors won't be looking for the long-term growth potential of the resale value of the stock, but simply a share of the profit." "Just read the book Flash Boys by Michael Lewis.  It describes this process in detail, albeit a bit more dramatically than it has to.  Basically what ""HFTs"" (high frequency traders) do is they set up their line to the exchange so its microseconds faster than everyone else.  Then they test out the market with tiny orders, seeing how fast it's getting filled - if these are getting filled immediately, it probably means there's a big order coming in from an investor.  So the algorithm - and it's all algo-based obviously because no human can remotely hope to catch this - will detect that as soon as there's a spike in volume, it will buy all of the volume at the current price, and sell it back for higher, forcing the big investor to take on higher prices.    Another case is that some HFTs can basically buy the entire trade book from an exchange like Nasdaq.  So every time someone places a market order for 200 shares of a 6.5 stock, the HFT will see it, buy up all the current stock from say 6.5-6.6 and sell it back at 6.7.  Not rocket science if you already get info about the trade coming in, in fact this is basically market making but performed by an ""evil HFT"" instead of a ""trustworthy bank.""    But honestly there are a lot more ways to make money from HFT than front-running, which isn't even possible anymore because exchanges no longer sell their books to HFTs." You can always trade at bid or ask price (depending if you are selling or buying). Market price is the price the last transaction was executed at so you may not be able to get that. If your order is large then you may not even be able to get bid/ask but should look at the depth of the order book (ie what prices are other market participants asking for and what is the size of their order). Usually only fast traders will trade at bid/ask, those who believe the price move is imminent. If you are a long term trader you can often get better than bid or ask by placing a limit order and waiting until a market participant takes your offer. If you want to invest in the Windows Phone, then you go and find out who makes the Windows Phone i.e. Microsoft. Then you go and decide if Windows Phone is successful will the share price of Microsoft go up (own research/deduction) and if you think that the price of Microsoft has a positive correlation with the Windows Phone, then you could buy shares of Microsoft. There is no way to invest directly in individual products on stock exchanges, you are generally investing in the companies that produce them. You find the ticker of a company by googling. NASDAQ: MSFT Any large stockbroker will offer trading in US securities. As a foreign national you will be required to register with the US tax authorities (IRS) by completing and filing a W-8BEN form and pay US withholding taxes on any dividend income you receive.  US dividends are paid net of withholding taxes, so you do not need to file a US tax return.  Capital gains are not subject to US taxes.  Also, each year you are holding US securities, you will receive a form from the IRS which you are required to complete and return. You will also be required to complete and file forms for each of the exchanges you wish to received market price data from. Trading will be restricted to US trading hours, which I believe is 6 hours ahead of Denmark for the New York markets.  You will simply submit an order to the desired market using your broker's online trading software or your broker's telephone dealing service. You can expect to pay significantly higher commissions for trading US securities when compared to domestic securities. You will also face potentially large foreign exchange fees when exchaning your funds from EUR to USD. All in all, you will probably be better off using your local market to trade US index or sector ETFs. You can make a purchase at the after market price by sending an order that gets executed in after market. Often times these are called Extended orders, or EXT. With an EXT limit order it will place the bid on the after market hours order book. If you get filled, then you have the shares.  This is the answer.
