Understanding about Williams' Alligator Indicator?
Is that indicator can only be used for short-term trade? First of all, indicator works perfect during trends and oscillator works perfectly in the range market(or flat market). So, indicator can be used for long term, as well as short term. I mean if it is a range market, using this or any other indicator will not help much, so it you should consider market direction first. If it can be used to long-term trade, is there something I need to change from the parameters used? like, only using SMMA(5,8,13)? The parameters are there to change them. Of course you can change them based on your trading style. Considering my statement above does not mean that trading is very easy. I never use indicators alone to make trading decisions. It is always good to use oscillator to filter out bad trading signals.
"I expect that data may be copyright. Data that's published (e.g. on a newsfeed or web site) is subject to terms of use. Standard & Poor's web site says, about the Shiller indexes, Who do I contact at S&P to license my   use of these indices?   Questions   regarding licensing the   S&P/Case-Shiller Home Price Indices   can be addressed to:  Bo Chung    Managing Director    bo_chung@standardandpoors.com,   +1.212.438.3519 As for 'recording' the information yourself, that may depend on how and where (e.g. from what source) you're recording it. If for example you tried to record prices from the Canadian MLS (Realtor's) network, they too have their own terms of use on the data they publish. Copyright laws vary from country to country (and terms of use certainly vary): for example see http://en.wikipedia.org/wiki/Feist_v._Rural which is case law about copyrighting a phone directory in the USA, and contrast that with http://en.wikipedia.org/wiki/Database_right which is European legislation. So who owns data if it is determined by free market? I guess that ""determined by free market"" means that buyers and sellers are publishing their offers-to-buy and their offers-to-sell, and I guess that the publisher (e.g. the stock exchange) has 'terms of use' about the data (the offers) that they're publishing." Whilst it is true that they do not have a conference call every time a rating is produced, the parameters of a natural oligopoly do indicate that there are negative effects of deviating too much from the other members of an oligopoly.   There are instances of rating agencies (Moody's) giving lower ratings to punish the issuer for going elsewhere (Re Hannover), but usually a slightly lower rating may be acceptable and is usually corrected to be in line with the competitor shortly afterwards. The power, arguably, is with the issuer in this sense because they can take their business to the 3rd member (Fitch) if the rating is too low from one of the Big Two. The preservation of the 'Big Two', for so long, is arguably testament to the S&amp;P and Moody's understanding of these parameters  If the answer is not micromanaging, what do you think it is out of interest? My understanding is that fentanol should only be prescribed for cancer pain. Any other indication is inappropriate. But that most of the fentanol is illegally mixed in heroin, made in China and contributes to a lot of deaths. That isn't coming from doctors. Is there an indicator about what percentage must be paid when?  Where does economics end and finance start?  I feel quite geeky, but I have been studying a bit of finance, and listening to bloomberg while I work (I am software dev) and want to understand everything :D  edit: just found about this [https://www.google.com/publicdata](https://www.google.co.uk/publicdata/explore?ds=ds22a34krhq5p_&amp;met_y=gd_pc_gdp&amp;idim=country:pt:es:el&amp;hl=en&amp;dl=en#!ctype=l&amp;strail=false&amp;bcs=d&amp;nselm=h&amp;met_y=gd_mio_eur&amp;scale_y=lin&amp;ind_y=false&amp;rdim=country_group&amp;idim=country:pt:es:el:de:fr:uk&amp;idim=country_group:eu&amp;ifdim=country_group&amp;hl=en_US&amp;dl=en&amp;ind=false) A couple ways, but its not a guarantee.  You have to have special charts. Instead of each tick being 1 min, 5 min, or whatever, it is a set number of trades. Say 2000. Since retail investors only buy and sell in small amounts, there will be small volume per tick. An institutional investor, however, would have a much much higher trade lot size, even if using an algo. Thus, large volume spikes in such a chart would signal institutional activity over retail. Similarly, daily charts showing average trade size can help you pick out when institutional activity is highest, as they have much larger trade sizes. You could also learn how the algos work and look for evidence one is being used. ie every time price hits VWAP a large sell order goes through would indicate an institutional investor is selling, especially if it happens multiple times in a row. based on my understanding of your query...well you need to understand ATM and ITM options. The  delta and gamma factor specifically. Usually delta of ATM is around 0.5 while ITM option is above than that say 0.6 or 0.8 or 0.9 and deep ITM is very close to 1. for every movement of 1 buck the ITM will move say 1.6, ATM 0.5 and OTM 0.3 approx Say a ABC stock price is Rs. 300 so if you check option chart you try to see which one is closer. Suppose you find strikeprice of 320 / 300 / 280. So  320 is ITM, 300 is ATM and 280 is OTM for call options. So will the delta value (e.g 0.66 / 0.55 / 0.35). So suppose if stock price rise by 7% i.e Rs. 321 then strikeprice will rise simultaneously. Say ATM CE300 is rs.10 it will start rising by 0.55 i.e. Rs.10.55. The moment the share price move from Rs.300 to Rs.320 your ATM will turn to ITM. Now the tricker part if you buy OTM and the share price rise by 15% your OTM will now become ITM and your profit will roll around 100% to 120% approx. Hope it answers your query The indication is based on the average Buy-Hold-Sell rating of a group of fundamental analysts. The individual analysts provide a Buy, Hold or Sell recommendation based on where the current price of the stock is compared to the perceived value of the stock by the analyst.  Note that this perceived value is based on many assumptions by the analyst and their biased view of the stock. That is why different fundamental analysts provide different values and different recommendations on the same stock. So basically if the stock's price is below the analyst's perceived value it will be given a Buy recommendation, if the price is equal with the perceived value it will be given a Hold recommendation and if the price is more than the perceived value it will be given a Sell recommendation. As the others have said this information IMHO is useless. "(1) I think the phrase ""Variable Annuity"" is a glowing red flag. A corollary to that is that any strategy that uses insurance for a purpose (e.g. tax avoidance) other than protecting against loss rates at least a yellow flag. (2) The other really obvious indicator is a return that is completely out of whack with the level of risk they are saying the investment has. For example, if someone promises a 10% annual return that is ""Completely Safe"" or ""Very low risk"", Run. (3) If it is advertised on tv/radio, or all your friends are talking about it at parties. Stay away. Example: Investing in Gold Coins or the hot Tech IPO. (4) The whole sales pitch relies on past returns as proof that the investment will do well without any real discussion of other reasons it will continue to to well. Beware the gambler's fallacy. (5) Finally, be very wary of anyone who has some sort of great investment plan that they will teach you if you just pay $X or go to their seminar. Fee based advice is fine, but people selling a get rich quick vehicle typically know the real way to get rich is to get suckers to pay for their seminars."
