Are spot market ,regular market and ready market same in stock trading if not then what is the difference?
"So, the term ""ready market"" simply means that a market exists in which there are legitimate buy/sell offers, meaning there are investors willing to own or trade in the security. A ""spot market"" means that the security/commodity is being delivered immediately, rather at some predetermined date in the future (hence the term ""futures market"").  So if you buy oil on the spot market, you'd better be prepared to take immediate delivery, where as when you buy a futures contract, the transaction doesn't happen until some later date.  The advantage for futures contract sellers is the ability to lock in the price of what they're selling as a hedge against the possibility of a price drop between now and when they can/will deliver the commodity.  In other words, a farmer can pre-sell his grain at a set price for some future delivery date so he can know what he's going to get regardless of the price of grain at the time he delivers it.  The downside to the farmer is that if grain prices rise higher than what he sold them for as futures contracts then he loses that additional money.  That's the advantage to the buyer, who expects the price to rise so he can resell what he bought from the farmer at a profit. When you trade on margin, you're basically borrowing the money to make a trade, whether you're trading long (buying) or short (selling) on a security.  It isn't uncommon for traders to pledge securities they already own as collateral for a margin account, and if they are unable to cover a margin call then those securities can be liquidated or confiscated to satisfy the debt.  There still may even be a balance due after such a liquidation if the pledged securities don't cover the margin call. Most of the time you pay a fee (or interest rate) on whatever you borrow on margin, just like taking out a bank loan, so if you're going to trade on margin, you have to include those costs in your calculations as to what you need to earn from your investment to make a profit. When I short trade, I'm selling something I don't own in the expectation I can buy it back later at a lower price and keep the difference.  For instance, if I think Apple shares are going to take a steep drop at some point soon, I can short them.  So imagine I short-sell 1000 shares of AAPL at the current price of $112.  That means my brokerage account is credited with the proceeds of the sale ($112,000), and I now owe my broker 1000 shares of AAPL stock.  If the stock drops to $100 and I ""cover my short"" (buy the shares back to repay the 1000 I borrowed) then I pay $100,000 for them and give them to my broker.  I keep the difference ($12,000) between what I sold them for and what I paid to buy them back, minus any brokerage fees and fees the broker may charge me for short-selling. In conclusion, a margin trade is using someone else's money to make a trade, whether it's to buy more or to sell short.  A short trade is selling shares I don't even own because I think I can make money in the process. I hope this helps."
"With stocks, you can buy or sell. If you sell first, that's called 'shorting.' As in ""I think linkedin is too high, I'm going to short it."" With options, the terminology is different, the normal process is to buy to open/sell to close, but if you were shorting the option itself, you would first sell to open, i.e you are selling a position to start it, effectively selling it short. Eventually, you may close it out, by buying to close.  Options trading is not for the amateur. If you plan to trade, study first and be very cautious." There are several reasons it is not recommended to trade stocks pre- or post-market, meaning outside of RTH (regular trading hours). Since your question is not very detailed I have to assume you trade with a time horizon of at least more than a day, meaning you do not trade intra-day. If this is true, all of the above points are a non-issue for you and a different set of points becomes important. As a general rule, using (3) is the safest regardless of what and how you trade because you get price guarantee in trade for execution guarantee. In the case of mid to longer term trading (1 week+) any of those points is viable, depending on how you want to do things, what your style is and what is the most comfortable for you. A few remarks though: (2) are market orders, so if the open is quite the ride and you are in the back of the execution queue, you can get significant slippage. (1) may require (live) data of the post-market session, which is often not easy to come by for the entire US stock universe. Depending on your physical execution method (phone, fax, online), you may lack accurate information of the post-market. If you want to execute orders based on RTH and only want to do that after hours because of personal schedule constraints, this is not really important. Personally I would always recommend (3), independent of the use case because it allows you more control over your orders and their fills. TL;DR: If you are trading long-term it does not really matter. If you go down to the intra-day level of holding time, it becomes relevant. "For any large company, there's a lot of activity, and if you sell at ""market"" your buy or sell will execute in seconds within a penny or two of the real-time ""market"" price.  I often sell at ""limit"" a few cents above market, and those sell within 20 minutes usually.  For much smaller companies, obviously you are beholden to a buyer also wanting that stock, but those are not on major exchanges.  You never see whose buy order you're selling into, that all happens behind the curtain so to speak." I think it all boils down to which is your priority.   So it all depends. People that want the stock sooOoooo badly will definitely go for the market order. To add to @Victor 's answer; if you are entering a market order, and not a limit order (where you set the price you want to buy or sell at), then the Ask price is what you can expect to pay to purchase shares of stock in a long position and the Bid price is what you can expect to receive when you sell stock you own in a long position. "An attempt at a simple answer for the normal investor: A normal investor buys stock then later sells that stock. (This is known as ""going long"", as opposed to ""going short"").  For the normal investor, a stop order (of either kind) is only used when selling. A stop-loss sell order (or stop sell) is used to sell your stock when it has fallen too much in price, and you don't want to suffer more losses.  If the stock is at $50, you could enter a stop sell at $40, which means if the stock ever falls to $40 or lower, your stock will be sold at whatever price is available (e.g. $35). A stop-loss limit sell order (or stop limit sell) is the same, except you are also saying ""but don't sell for less than my limit price"".  So you can enter a stop limit sell at $40 with a limit of $39, meaning that if the stock falls to $40, you will then have a limit order in effect to sell the stock at $39 or higher.  Thus your stock will never be sold at $35 or any value below $39, but of course, if the stock falls fast from $40 to $35, your limit sell at $39 will not be done and you will be left still owning the stock (worth at that moment $35, say)." "Trading on specific ECNs is the easy part - you simply specify the order routing in advance.  You are not buying or selling the *exact* same shares.  Shares are fungible - so if I simultaneously buy one share and sell another share, my net share position is zero - even if those trades don't settle until T+3.  PS ""The Nasdaq"" isn't really an exchange in the way that the CME, or other order-driven markets are.  It's really just a venue to bring market makers together.  It's almost like ""the internet,"" as in, when you buy something from Amazon, you're not buying it from ""the internet,"" but it was the internet that made your transaction with Amazon possible." There is no difference.  When dealing with short positions, talking about percentages become very tricky since they no longer add up to 100%.  What does the 50% in your example mean?  Unless there's some base amount (like total amount of the portfolio, then the percentages are meaningless.  What matters when dealing with long and short positions is the net total - meaning if you are long 100 shares on one stock trade and short 50 shares on another, then you are net long 50 shares. "But I don't see how it's any different than buying a stock at a low price and holding on to it for some months. Based on your question, I would say the difference is time. Day trading by its nature is a 6-hour endeavor. If you buy low and are planning to sell high, then you only have a few hours to make this happen. As a previous poster mentioned, there is a lot of ""white noise"" that occurs on a weekly/daily/hourly/min basis. Long-term investors have the time to wait it out. Although, as a side note, if you were a buy-and-hold investor from the 1960s-early 1980s, then buy and hold was not very good. Is it just the psychological/addictive aspect of it? This is the biggest reason. Day trading is stressful and stress can cause financially destructive decisions such as over-leveraging, over-trading, etc. Why is day trading stressful? Because you are managing hundreds to thousands of trades a year. When combined with the lack of time in a day to make moves, it becomes stressful. Also, many day traders do it full time. Which adds to the pressure to be correct and to be incredible at money managment. A lot of buy-and-hold investors have full time jobs and may only check their positions every month or so." A trailing stop will sell X shares at some percentage below the current market price.  Putting in this order with a 10% trailing stop when the stock price is $50 will sell the stock when it hits $45.  It's a market order at that point (see below). A stop order will sell the stock when it reaches a certain price.  The stop order becomes a market order when the magic price is hit.  This means that you may not sell it at or below your price when the order is executed.  But the stock will sell faster because the trader must execute. A stop limit order is the same as a stop order, except the stock won't be sold if it can't be gotten for the price.  As a result, the sell may not be executed. More information here. The difference between the two numbers is that the market size of a particular product is expressed as an annual number ($10 million per year, in your example).  The market cap of a stock, on the other hand, is a long-term valuation of the company. You cannot trade in pre-IPO shares of companies like Facebook without being an accredited investor. If a website or company doesn't mention that requirement, they are a scam. A legitimate market for private shares is SecondMarket. Forex vs Day Trading: These can be one and the same, as most people who trade forex do it as day trading. Forex is the instrument you are trading and day trading is the time frame you are doing it in. If your meaning from your question was comparing trading forex vs stocks, then it depends on a number of things. Forex is more liquid so most professional traders prefer it as it can be easier to get in and out without being gapped. However, if you are not trading large amounts of money and you stay away from more volatile stocks, this should not matter too much. It may also depend on what you understand more and prefer to trade. You need to be comfortable with what you are trading. If on the other hand you are referring to day trading vs longer term trading and/or investing, then this can depend largely on the instrument you are trading and the time frame you are more comfortable with. Forex is used more for shorter term trading, from day trading to having a position open for a couple of days. Stocks on the other hand can be day traded to traded over days, weeks, months or years. It is much more common to have positions open for longer periods with stocks. Other instruments like commodities, can also be traded over different time frames. The shorter the time frame you trade the higher risk involved as you have to make quick decisions and be happy with making a lot of smaller gains with the potential to make a large loss if things go wrong. It is best once again to chose a time frame you are comfortable with. I tend to trade Australian stocks as I know them well and am comfortable with them. I usually trade in the medium to long term, however I let the market decide how long I am in a position and when I get out of it. I try to follow the trend and stay in a position as long as the trend continues. I put automatic stop losses on all my positions, so if the market turns against me I am automatically taken out. I can be in a position for as little as a day (can happen if I buy one day and the next day the stock falls by 15% or more) to over a year (as long as the trend continues). By doing this I avoid the daily market noise and let my profits run and keep my losses small. No matter what instrument you end up trading and the time frame you choose to trade in, you should always have a tested trading plan and a risk management strategy in place. These are the areas you should first gain knowledge in to further your pursuits in trading. "If the price used to be 2.50 but by the time you get in an order it's 2.80, you're going to have to pay 2.80. You can't say, ""I want to buy it at the price from an hour ago"". If you could, everybody would wait for the price to go up, then buy at the old price and have an instant guaranteed profit. Well, except that when you tried to sell, I suppose the buyer could say, ""I want to pay the lower price from last July"". So no, you always buy or sell at the current price. If you submit an order after the markets close, your broker should buy the stock for you as soon as possible the next morning. There's no strict queue. There are thousands of brokers out there, they don't take turns. So if your broker has 1000 orders and you are number 1000 on his list, while some other broker has 2 orders and number 1 is someone else wanting to buy the same stock, then even if you got your order in first, the other guy will probably get the first buy. LIFO and FIFO refer to any sort of list or queue, but don't really make sense here. When the market opens a broker has a list of orders he received overnight, which he might think of as a queue. He presumably works his way down the list. But whether he follows a strict and simple first-in-first-out, or does biggest orders first, or does buys for stocks he expects to go up today and sells for stocks he expects to go down today first, or what, I don't know. Does anybody on this forum know, are there rules that say brokers have to go through the overnight orders FIFO, or what is the common practice?" "For some situations, an MBA can be overrated in the sense that given the cost of time and money, it isn't going to be a great return in some cases. There can be tens of thousands of dollars and a couple of years to get an MBA that some people believes should automatically make them worth $x more in their salary and life should be simple. I'd likely inquire as to what expectations do you have for what an MBA will do for you. Are you expecting to make connections in getting the degree? Are you expecting to learn about how to run a business from the coursework? Are you expecting something else? Depending on what you are expecting, I could see MBA as being anything from a great choice to a lousy choice for people. As noted by Pete Belford's comment, an MBA from a ""degree mill"" would be all but worthless. Where you go can reflect the value of the education as some universities are known for their program about this such as Ivy League schools."
