How to map stock ticker symbols to ISIN (International Securities Identification Number)?
There is no simple way to convert an ISIN into a stock ticker symbol. The only way to even attempt to do so is to map the ISIN to a CUSIP or SEDOL or other national identifier and then map that identifier to a stock ticker symbol. "It is possible to make a REST API call providing the ISIN to get the ticker in the response:  Python code for getting ticker for ISIN=US4592001014:  import requests  url = 'https://api.openfigi.com/v1/mapping'  headers = {'Content-Type':'text/json', 'X-OPENFIGI-APIKEY':'myKey' }  payload = '[ {""idType"":""ID_ISIN"",""idValue"":""US4592001014""}]'   r = requests.post(url, data=payload, headers=headers)"
Neither site offers index futures or options pricing.  Your best best is likely to get the quote from a broker who supports trading those vehicles. Free sites usually limit themselves to stocks and sometimes to options chains -- the exception is Reuters where just about any security for which you have the reuters formatted trading symbol can be quoted. ACWI refers to a fund that tracks the MSCI All Country World Index, which is  A market capitalization weighted index designed to provide a broad measure of equity-market performance throughout the world. The MSCI ACWI is maintained by Morgan Stanley Capital International, and is comprised of stocks from both developed and emerging markets.  The ex-US in the name implies exactly what it sounds; this fund probably invests in stock markets (or stock market indexes) of the countries in the index, except the US. Brd Mkt refers to a Broad Market index, which, in the US, means that the fund attempts to track the performance of a wide swath of the US stock market (wider than just the S&P 500, for example). The Dow Jones U.S. Total Stock Market Index, the Wilshire 5000 index, the Russell 2000 index, the MSCI US Broad Market Index, and the CRSP US Total Market Index are all examples of such an index. This could also refer to a fund similar to the one above in that it tracks a broad swath of the several stock markets across the world. I spoke with BNY Mellon about the rest, and they told me this: EB - Employee Benefit (a bank collective fund for ERISA qualified assets) DL - Daily Liquid (provides for daily trading of fund shares) SL - Securities Lending (fund engages in the BNY Mellon securities lending program) Non-SL - Non-Securities Lending (fund does not engage in the BNY Mellon securities lending program) I'll add more detail. EB (Employee Benefit) refers to plans that fall under the Employee Retirement Income Security Act, which are a set a laws that govern employee pensions and retirement plans. This is simply BNY Mellon's designation for funds that are offered through 401(k)'s and other retirement vehicles. As I said before, DL refers to Daily Liquidity, which means that you can buy into and sell out of the fund on a daily basis. There may be fees for this in your plan, however. SL (Securities Lending) often refers to institutional funds that loan out their long positions to investment banks or brokers so that the clients of those banks/brokerages can sell the shares short. This SeekingAlpha article has a good explanation of how this procedure works in practice for ETF's, and the procedure is identical for mutual funds: An exchange-traded fund lends out shares of its holdings to another party and charges a rental fee. Running a securities-lending program is another way for an ETF provider to wring more return out of a fund's holdings. Revenue from these programs is used to offset a fund's expenses, which allows the provider to charge a lower expense ratio and/or tighten the performance gap between an ETF and its benchmark. "Thanks for pointing out [the study](http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1748851). It's a slightly different cause than what I was describing when I posted this. Specifically, they show an effect not when the names get confused, but rather when the name similarity simply brings more attention to the stock. I was surprised nobody mentioned that in response to my post.  But also interesting is that they had to control for simple confusion between stock symbols, which implies that ticker confusion has a known effect. So I dug into research on that and quickly found [this study](http://www.efmaefm.org/0EFMAMEETINGS/EFMA%20ANNUAL%20MEETINGS/2010-Aarhus/EFMA2010_0161_fullpaper.pdf) found ""a high positive correlation between returns on two matching stocks with similar ticker symbols""." I have had this happen a couple of times because of splits or sales of portions of the company.  The general timeline was to announce how the split was to be handled; then the split; then a freeze in purchasing stock in the other company; then a freeze in sales; followed by a short blackout period; then the final transfers to funds/options/cash based on a mapping announced at the start of the process. You need to answer two questions: To determine if the final transactions will make the market move you have to understand how many shares are involved compared to the typical daily volume. There are two caveats: professional investors will be aware of the transaction date and can either ignore the employee transactions or try and take advantage of them; There may also be a mirroring set of transactions if the people left in the old company were awarded shares in your company as part of the sale. If you are happy with the default mapping then you can do nothing, and let the transaction happen based on the announced timeline. It is easy, and you don't have to worry about deadlines. If you don't like the default mapping then you need to know when the blackout period starts, so you don't end up not being able to perform the steps you want when you want.  Timing is up to you. If the market doesn't like the acquisition/split it make make sense to make the move now, or wait until the last possible day depending on which part they don't like. Only you can answer that question. Hi all - I'm a UX designer working on a design challenge as part of an interview. I'm looking to learn more about how traders select securities to monitor and how they create alerts to track values of interest.  If you could walk me through the last time you: - Decided on a security you wanted to monitor and set up a system to monitor the security - Which fields (e.g., last price, volume, etc) you were most interested in tracking for that security - If you created alerts for any fields (e.g., price)  - If you did create an alert: what the alert was for, the steps you took to create it, and how the alert notified you of a change  Any information you can provide would be super helpful! Please include your current role and the number of years you have experience trading. Even if you're not currently a trader or relatively new/in school any answers would be helpful!

For example you could use candle stick reversal patterns on monthly charts, weekly charts, daily charts or intra-day charts like one hour, or even one minute charts. Obviously if you are looking for longer term positions you would be looking at daily, weekly or monthly charts and if you are looking for shorter term positions you would be looking at intra-day to daily charts.  You can also use a combination of time frames - for example, if you are trying to enter a trade over a long-term uptrend you could use a weekly chart to determine if the stock is currently uptrending and then use a daily chart to time your entry into the trade. Most patterns in general don't really determine how long you will be in the trade but instead usually can provide an entry trigger, a stop loss location and possibly a profit target.  So in general a pattern which is being used to enter into longer term trades on weekly charts can also be used to enter shorter term trades on intra-day charts. "I agree with the answer by @Michael that this number doesn't exist.  It's hard to see what use it would have and it would be difficult to track. I'm writing a separate answer because I also disagree with the premise of your question:  Individual shares of stock have never to my knowledge had such a number.  Your comment about numbers on stock certificates identifies the certificate document, which will generally represent multiple shares of stock.  That number no more identifies a single share of stock than the serial number on a $10 bill identifies any one of the ten dollars it represents.  Even at the ""collective"" unit of $10, when the bill is eventually replaced with a new one, the new bill has a new number.  No continuity."
