Historical Tick Data Request Hours Sep 11, 2018 12:51 PM
(Total replies: 12)
@bigjake - if you are writing code in C#, try using Mathieu P C# Service. https://github.com/mathpaquette/IQFeed.CSharpApiClient To Avoid Time Out, 1. Alternatively, request 1 day of tick data and loop - 2. Alternatively, have upto 15 requests simulataneously to request Tick Data IMO IQfeed is a great product, i had to figure things out through trial and error. AK786

No way to query historical (expired) equity option chain symbols? Aug 27, 2018 11:26 AM

To all IQFeed Forum Readers, i just wanted to share that I have been using Matt P. (IQfeed Csharp Client) and its phenomenal. Tick Data download for all US Equities (Approx 8000) can get done within 15 mins / each day. Options data download which can have over a million queries for entire dataset - lightning fast even. I downloaded all US Equity Options for 6 months which has "Expired" + "Recently Traded" Options. The Live Data Client runs on super low CPU and memory. Check out his code, he has saved me tons of time. I am very grateful to him for responding to my queries almost immediately and resolving minor bugs if any. Thank you Matt P. and all his IQFeed github contributors. AK786

Thank you J - you are correct, Tim, Regarding this - I was making a mistake at my end. This issue is resolved. Please let me know about the other situation related to last trade date (after expiration) - its still not a problem, if its a system issue at your end. Thanks AK **** Also another question is how Far Options History do you carry, i tried requesting Options Tick Data between <OptionsBeginDate value= "20180501"/> <OptionsEndDate value= "20180713"/> for all options in (From the above attached file) for Equity Symbol AAPL and i did not get a single data tick data history *** AK786

Tim, This is WRT the post from: *** Posted: Aug 7, 2018 08:32 AM Quote Post Reply To Post Msg. 22 of 33 Actually, the expiration date is the blank field, the other date is the last traded date. I'll correct the email above to be accurate. Expiration can be inferred from the symbol, but we will look into that prior to release as well. Tim *** I parsed out Sample Data from the IEOptions File from 20150101 to 20180713 Somehow, for the a Large Number of Options, The Last Traded Date is after the Expiration Date. Can you kindly explain how that might have happened. Please see attached. I know you will be generating the latest IEOptions FIle tomm, so I wanted to make sure your efforts do not go to waste. Thank you AK786

Tim, This message is with reference to your post from: *** Posted: Aug 2, 2018 07:35 AM Quote Post Reply To Post Msg. 18 of 30 There is some work being done on our website currently and that bumped the automation back, but I did place a file up a couple weeks ago for everything that was expired up to that date if you want to take a look at it. ftp://www.dtniq.com/beta/IEOPTION.zip *** Goal: Get Options Tick Data for Expired Options and Current Options for the 6 months. I downloaded this file and parsed the file. However the last trade date is 20180713 Q1. I am assuming that ftp://www.dtniq.com/beta/IEOPTION.zip contains only Option Symbols that have expired and the last date they traded? For example, 20180710 has only 24103 symbols as you can see below and http://www.dtniq.com/product/mktsymbols_v2.zip file contains approx 900k option symbols which are all currently trading symbols. Can you please verify this assumption is accurate Q2. Can you kindly update this file ftp://www.dtniq.com/beta/IEOPTION.zip until 20180817 (The last date is 20180713) After this - i can get latest symbols daily from http://www.dtniq.com/product/mktsymbols_v2.zip and request IQFeed data. Your help is very appreciated. Thank you. Please see attached file: (IEOptionsFile_DateSym.xlsx) Date Symbols 20180713 603 20180711 130 20180710 24159 20180709 112 20180707 385 20180706 403 20180703 27661 20180702 87 20180701 386 ... AK786

data_collector, here is something i did to parse out the code from Matt P. I am storing Flat Files - you can write all teh data to a C# datatable object. His code is awesome and has saved me 50+ hours - higher performance than the IQFeed examples IMO. Also if there is bug, he serves us by fixing it in just a few hours if you send him an email var tickData = await lookupClient.Historical.ReqHistoryTickTimeframeAsync(symbol, requestStartDate, requestEndDate, null, null, null, DataDirection.Oldest); CreateTaskStoreTickMessages(symbol, tickData); void CreateTaskStoreTickMessages(string symbol, IEnumerable<TickMessage> tickMessages) { Task.Factory.StartNew(() => StoreTickMessages(symbol, tickMessages, TickDirectory)); } List<double> tickMessagesStoreRunTime = new List<double>(); object tickMessagesStoreLockObject = new object(); static string TickFileHeader = "Timestamp,Last,LastSize,TotalVolume,Bid,Ask,TickId,BasisForLast,TradeMarketCenter,TradeConditions"; void StoreTickMessages(string symbol, IEnumerable<TickMessage> tickMessages, string baseTickDirectory) { DateTime storeTickMessagesStartTime = DateTime.Now; // All the Tick Data gets stored into "Date" Created Files By Symbol Name List<TickMessage> tickMessagesCurrentDate = new List<TickMessage>(); DateTime previousDate = DateTime.MaxValue; List<DateTime> datesProcessing = new List<DateTime>(); foreach (TickMessage message in tickMessages) { DateTime dateTime = message.Timestamp; DateTime date = message.Timestamp.Date; // New Date in Tick Messages if (!datesProcessing.Contains(date)) { datesProcessing.Add(date); // Record Previous Date for the First Time if (previousDate == DateTime.MaxValue) { previousDate = date; } else // Store the Previous Dates Data once New TimeStamp is triggered { StoreTickMessagesByDate(baseTickDirectory, previousDate, symbol, tickMessagesCurrentDate); // Reset Data Structures tickMessagesCurrentDate = new List<TickMessage>(); previousDate = date; } } tickMessagesCurrentDate.Add(message); } // Store Data from Last Date StoreTickMessagesByDate(baseTickDirectory, previousDate, symbol, tickMessagesCurrentDate); TimeSpan storeTickMessagesRunTime = DateTime.Now.Subtract(storeTickMessagesStartTime); double runTimeSeconds = Math.Round(storeTickMessagesRunTime.TotalSeconds, 4); double avgRunTimeSeconds = 0; lock (tickMessagesStoreLockObject) { tickMessagesStoreRunTime.Add(runTimeSeconds); avgRunTimeSeconds = Math.Round(GetAverage(tickMessagesStoreRunTime), 2); } logger.Trace("StoreTickMessages: " + " Symbol: " + symbol + " Run Secs: " + runTimeSeconds + " Avg Run Secs: " + avgRunTimeSeconds); } void StoreTickMessagesByDate(string TickDirectory, DateTime date, string symbol, List<TickMessage> tickMessages) { string TickDirectoryDate = TickDirectory + date.ToString(SystemInfrastructure.DateFormat) + "\\"; // Create Date Directory only once if (false == Directory.Exists(TickDirectoryDate)) { Directory.CreateDirectory(TickDirectoryDate); } string symbolFileName = TickDirectoryDate + symbol + ".csv"; using (StreamWriter sw = new StreamWriter(symbolFileName)) { sw.WriteLine(TickFileHeader); foreach (TickMessage tickMessage in tickMessages) { string timeStamp = tickMessage.Timestamp.ToString(IQFeed.CSharpApiClient.Lookup.Historical.Messages.TickMessage.TickDateTimeFormat); double Last = Math.Round(tickMessage.Last, 4); int LastSize = tickMessage.LastSize; long TotalVolume = tickMessage.TotalVolume; double Bid = Math.Round(tickMessage.Bid, 2); double Ask = Math.Round(tickMessage.Ask, 2); long TickId = tickMessage.TickId; char BasisForLast = tickMessage.BasisForLast; int TradeMarketCenter = tickMessage.TradeMarketCenter; string TradeConditions = tickMessage.TradeConditions; string tickMessageCSV = TickMessageCSV(timeStamp, Last, LastSize, TotalVolume, Bid, Ask, TickId, BasisForLast, TradeMarketCenter, TradeConditions); sw.WriteLine(tickMessageCSV); } } } AK786

This message is for everyone who has been looking for "Reducing the number of Callbacks" to IQfeed for requesting options tick or daily data on a Daily Basis to avoid "False Positives" https://www.theocc.com/webapps/cont-volume-download?reportDate=20170103&format=txt where 20170103 = TradeDate (this provided us with "Expirations" where Trading happened If you are just focused on Front 2 months, that reduced the load even further. This is not a perfect solution but reduces the load. There are many different queries available for Batch Processing https://www.theocc.com/market-data/batch-processing.jsp#http_volume_download_contract_date AK786
