what is this type of stock trade?
try to sell if today's google stock goes above 669$ This is Relative/Pegged-to-Primary Order with a Limit Price of $669 and an offset from National Best Offer of $0.00, but it is no different than an Market Order if the market price is $669 to begin with.  do not sell if the stock keeps climbing beyond 669 unless there is a down tick of 20cents is seen This is a Trailing Stop Order with a Trailing Amount of $0.20. It sells if the market price dropped $0.20 from the peak.  The two orders are contradictory. From your comments, I think the following is what you want: Submit Trailing Stop Order when market price is above $669.  Cancel Trailing Stop Order before the end of the day and Submit Relative/Pegged-to-Primary Order to Sell. "I think that pattern is impossible, since the attempt to apply the second half would seem to prevent executing the first. Could you rewrite that as ""After the stock rises to $X, start watching for a drop of $Y from peak price; if/when that happens, sell."" Or does that not do what you want? (I'm not going to comment on whether the proposed programmed trading makes sense. Trying to manage things at this level of detail has always struck me as glorified guesswork.)"
hello pointbox,  i enjoy getting in front of someone that does know what they are talking about, so i have a question for you...  could you give to us a textbook example of what a high frequency trade looks like? "Being ""long"" - expecting the price to go up to make a profit - is a two step process:  1) buy 2) sell Being ""short"" - expecting the price to go down to make a profit - is a 5 step process:  1) borrow someone else's asset 2) sell their asset on the open market to somebody else a third party 3) pocket the proceeds of the sell for your own account 4) buy an identical asset for a cheaper price 5) return this identical asset to the person that let you borrow their asset if this is successful you keep the difference between 3) and 4)" This is copying my own answer to another question, but this is definitely relevant for you: A bid is an offer to buy something on an order book, so for example you may post an offer to buy one share, at $5. An ask is an offer to sell something on an order book, at a set price. For example you may post an offer to sell shares at $6. A trade happens when there are bids/asks that overlap each other, or are at the same price, so there is always a spread of at least one of the smallest currency unit the exchange allows. Betting that the price of an asset will go down, traditionally by borrowing some of that asset and then selling it, hoping to buy it back at a lower price and pocket the difference (minus interest). Going long, as you may have guessed, is the opposite of going short. Instead of betting that the price will go down, you buy shares in the hope that the price will go up. So, let's say as per your example you borrow 100 shares of company 'X', expecting the price of them to go down. You take your shares to the market and sell them - you make a market sell order (a market 'ask'). This matches against a bid and you receive a price of $5 per share. Now, let's pretend that you change your mind and you think the price is going to go up, you instantly regret your decision. In order to pay back the shares, you now need to buy back your shares as $6 - which is the price off the ask offers on the order book. Similarly, the same is true in the reverse if you are going long. Because of this spread, you have lost money. You sold at a low price and bought at a high price, meaning it costs you more money to repay your borrowed shares. So, when you are shorting you need the spread to be as tight as possible. "People in this case, are large institutional investors. The ""bid ask"" spread is for ""small traders"" like yourself. It is put out by the so-called specialists (or ""market makers"") and is typically good for hundreds or thousands of shares at a time. Normally, 2 points on a 50 stock is a wide spread, and the market maker will make quite a bit of money on it trading with people like yourself. It's different if a large institution, say Fidelity, wants to sell, say 1 million shares of the stock. Depending on market conditions, it may have trouble finding buyers willing to buy in those amounts anywhere near 50. To ""move"" such a large block of stock, they may have to put the equivalent of K-Mart's old ""Blue Light Special"" on, several points below." Candlesticks and TA are a relic of pre-computer trading, period. Market makers use sophisticated algorithms not for trading, but manipulations. On the US markets, most index options are European style.  Most stock and ETF options are, as you noted, American style. "The process of borrowing shares and selling them is called shorting a stock, or ""going short.""  When you use money to buy shares, it is called ""going long."" In general, your strategy of going long and short in the same stock in the same amounts does not gain you anything.  Let's look at your two scenarios to see why. When you start, LOOT is trading at $20 per share.  You purchased 100 shares for $2000, and you borrowed and sold 100 shares for $2000.  You are both long and short in the stock for $2000.  At this point, you have invested $2000, and you got your $2000 back from the short proceeds.  You own and owe 100 shares. Under scenario A, the price goes up to $30 per share.  Your long shares have gone up in value by $1000.  However, you have lost $1000 on your short shares.  Your short is called, and you return your 100 shares, and have to pay interest.  Under this scenario, after it is all done, you have lost whatever the interest charges are. Under scenario B, the prices goes down to $10 per share.  Your long shares have lost $1000 in value.  However, your short has gained $1000 in value, because you can buy the 100 shares for only $1000 and return them, and you are left with the $1000 out of the $2000 you got when you first sold the shorted shares.  However, because your long shares have lost $1000, you still haven't gained anything.  Here again, you have lost whatever the interest charges are. As explained in the Traders Exclusive article that @RonJohn posted in the comments, there are investors that go long and short on the same stock at the same time.  However, this might be done if the investor believes that the stock will go down in a short-term time frame, but up in the long-term time frame.  The investor might buy and hold for the long term, but go short for a brief time while holding the long position. However, that is not what you are suggesting.  Your proposal makes no prediction on what the stock might do in different periods of time.  You are only attempting to hedge your bets.  And it doesn't work.  A long position and a short position are opposites to each other, and no matter which way the stock moves, you'll lose the same amount with one position that you have gained in the other position.  And you'll be out the interest charges from the borrowed shares every time. With your comment, you have stated that your scenario is that you believe that the stock will go up long term, but you also believe that the stock is at a short-term peak and will drop in the near future.  This, however, doesn't really change things much.  Let's look again at your possible scenarios. You believe that the stock is a long-term buy, but for some reason you are guessing that the stock will drop in the short-term.  Under scenario A, you were incorrect about your short-term guess.  And, although you might have been correct about the long-term prospects, you have missed this gain.  You are out the interest charges, and if you still think the stock is headed up over the long term, you'll need to buy back in at a higher price. Under scenario B, it turns out that you were correct about the short-term drop.  You pocket some cash, but there is no guarantee that the stock will rise anytime soon.  Your investment has lost value, and the gain that you made with your short is still tied up in stocks that are currently down. Your strategy does prevent the possibility of the unlimited loss inherent in the short.  However, it also prevents the possibility of the unlimited gain inherent in the long position.    And this is a shame, since you fundamentally believe that the stock is undervalued and is headed up.  You are sabotaging your long-term gains for a chance at a small short-term gain." NYSE and Nasdaq are secondary markets where stocks are bought or sold. The process of creating new stocks via IPO or private placements etc are called Private Market. The 'normal' series of events when trading a stock is to buy it, time passes, then you sell it. If you believe the stock will drop in price, you can reverse the order, selling shares, waiting for the price drop, then buying them back. During that time you own say, -100 shares, and are 'short' those shares. "Orders large enough to buy down the current Bid and Ask Book are common. This is the essential strategy through which larger traders ""Strip"" the Bid or Ask in order to excite motion in a direction that is favorable to their interests. Smaller traders will often focus on low float/small cap tickers, as both conditions tend to favor volatility on relatively small volume." News-driven investors tend to be very short-term focussed investors. They often trade by using index futures (on the S&P 500 index for instance). "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." Well, arbitrage is a simple mean reversion strategy which states that any two similar commodity with some price difference (usually not much)  will converge. So either you can bet on difference in prices in different exchanges or also you can bet on difference in futures value.  For example if current price of stock is 14$ and if futures price is 10$.  Then you can buy one futures contract and short one stock at the market price. This would lock in a profit of 4$ per share. Starting with the basics, you have the sell side (investment banks, Goldman Sachs) and the buy side (asset managers, Blackrock). The buy side are the clients of the sell side, directing trade flow through banks and using their research and taking part in origination and new issues. Basically both are currently under structural pressure from passive investing combined with new technology and regulation (MIFID 2 in Europe). "SELL -10 VERTICAL $IYR 100 AUG 09 32/34 CALL @.80 LMT 1) we are talking about options, these are a derivative product whose price is based on 6 variables. 2) options allow you to create risk out of thin air, and those risks come with shapes, and the only limit is your imagination (and how much your margin/borrowing costs are). Whereas a simple asset like the shares for $IYR only has a linear risk profile. stock goes up, you make money, stock goes down, you lose money, and that risk graph looks linear. a ""vertical"" has a nonlinear risk profile 3) a vertical is a type of ""spread"" that requires holding options that expire at the same time, but at different strike prices. 3b) This particular KIND of vertical is called a bear call spread (BCS). Since you are bearish (this makes money if the stock goes down, or stays in a very specific range) but are using calls which are a bullish options product. 4) -10 means you are selling the vertical. +10 means you are buying the vertical. A ""long"" vertical is initiated by buying an option closer to the money, and selling an option at a higher strike price. This would be +X A ""short"" vertical is initiated by selling an option closer to the money and buying an option at a higher strike price. The quantity would be -X 5) 32/34 stands for the strike prices. so you would be selling 10 call options at the 32 strike price, and buying 10 call options at the 34 strike price, both options expire in August 6) LMT stands for limit order, and $.80 is the limit order price that is desired. OPENING a vertical spread requires knowledge of options as well as how to send orders. MANAGING a vertical requires even more finesse, as you can ""leg-in"" and ""leg-out"" of spreads, without sending the entire order to the exchange floor at once. There is much to learn."
