go-iex's Issues

UDP -> NewPcapScanner

I am trying to pipe a UDP stream into the pcap parser. It seems to take a io.Reader which the UDP go package supports.

conn, _ := net.ListenMulticastUDP("udp", iface, addr)
packetDataSource, err := iex.NewPacketDataSource( conn )
if err != nil {
    panic(err)
}
pcapScanner := iex.NewPcapScanner(packetDataSource)
// decoding stuff here

However I get the following error:
panic: Unknown magic 80040001

Any insights would be greatly appreciated.

Thanks,

The HIST API provides data files containing IEXTP packet captures for the TOPS and DEEP endpoints each day. Implement parsers for these protocols. The specs are available here: https://www.iextrading.com/trading/market-data/#specifications

Bug in client.go in the method GetHistoricalDaily

No matter what parameter is passed to the method GetHistoricalDaily, the result is always the same.
The problem is that the parameter is not passed onwards to getJSON, it should be passed like this:

err := c.getJSON("/stats/historical/daily", req, &result)

pcap2json Unknown magic a0d0d0a

Hi there!

I really just wanted to checkout whats contained in the pcap files returned from the https://api.iextrading.com/1.0/hist endpoint.
I was testing the pcap2json utility with the example file available here:
https://www.googleapis.com/download/storage/v1/b/iex/o/data%2Ffeeds%2F20170911%2F20170911_IEXTP1_TOPS1.5.pcap.gz?generation=1505174874390598&alt=media

Output as follows:

pcap2json < 20170911_IEXTP1_TOPS1.5.pcap
2017/09/12 15:01:03 Unknown magic a0d0d0a

Had comparable errors with other pcap parsers. Wireshark seems to parse it just fine but I've got no clue how to decode the raw payload <.<
I'm on ubuntu 16.04 LTS using go 1.9.

Bug in Symbol structure definition

When fetching the /ref-data/symbols url from the web I get the response:

[{"symbol":"A","name":"Agilent Technologies Inc.","date":"2018-07-25","isEnabled":true,"type":"cs","iexId":"2"}, .....

However the Symbol structure in the project is defined as follows:

type Symbol struct {
	// Refers to the symbol represented in Nasdaq Integrated symbology (INET).
        **_Ticker string_**
	// Refers to the name of the company or security.
	Name string
	// Refers to the date the symbol reference data was generated.
	Date string
	// Will be true if the symbol is enabled for trading on IEX.
	IsEnabled bool
}

The Ticker field should be renamed to Symbol, otherwise it isn't decoded with the JSON and effectively, gets left out of the response of the method GetSymbols(). This is an important field as it is the identifier of every stock.

Implement WebSocket streaming APIs

How to access the values of a message struct?

Hi,
I'm currently using msg, err := pcapScanner.NextMessage() and I'm trying to access the values contained in the msg struct. When I try to access using msg.MessageType, I'm get an error:


./hello.go:69:51: msg.MessageType undefined (type iextp.Message has no field or method MessageType)

I know it has something to do with the inheritance between Message and other Message structs; what's the proper way of using this?

How to save the output to a json file?

The library prints out the values the values in the terminal, but there does not seem to be a way to save the output as a txt/json file. Is there a way to do this?

Some entries not parsed correctly when running pcap2json

Thanks for the great library!

When running main.go against the IEX pcap sample, some entries are not decoded to JSON correctly. The failed entries look like --> "WE2Bi5o3AroNFVpYSUVUICAgeEEPAAAAAAA="

Repro (on Windows)
go run C:\Users\user\Downloads\Projects\go-iex\pcap2json\main.go < 20180127_IEXTP1_TOPS1.6.pcap > iex.json

Also, it appears the output is truncated. For example, the last line in the output file is incomplete:
{"MessageType":81,"Flags":64,"Timestamp":"2018-01-27T17:35:26.6146978Z","Symbol":"AYT","BidSize":0,"BidPrice":0,

Iterate over data from a live multicast UDP stream of the DEEP feed example

Hi,

Thank you for putting this library together. Quick question - I tried the "Iterate over data from a live multicast UDP stream of the DEEP feed" example and I am not seeing any PriceLevelUpdate messages. Before I start digging in, I was curious whether you know something about using the DEEP UDP Multicast that I don't? Do you have to have a subscription with IEX to use it? Thank you for your time and help.

Also, I'm looking into the Socket.IO issue.

Errors when running example pcap download/parsing code

Thanks for writing this library, it's very helpful for me.

I'm new to Go, and currently trying to run the sample code in the readme. I've created a new directory in go/src, and when I try to run the file using go run testfile.go, I get the following error:

# command-line-arguments
./hello.go:33:19: cannot assign 1 values to 2 variables
./hello.go:33:45: cannot use resp.Body (type io.ReadCloser) as type iex.PacketDataSource in argument to iex.NewPcapScanner:
	io.ReadCloser does not implement iex.PacketDataSource (missing LinkType method)

As a Go newbie, I'd appreciate any help with understanding this error. Thanks!

Command not found

go install github.com/timpalpant/go-iex/pcap2json does not add a pcap2json path to the root directory making it unusable for an otherwise useful pcap2json tool.

iex stats types differ between intraday and daily historic

i am creating this issue to hopefully either fix the issue on the package level or iex api level.

here are two different api requests to iex:
https://iextrading.com/developer/docs/#historical-daily
and
https://iextrading.com/developer/docs/#recent

historical-daily

[
  {
    "date": "2017-05-09",
    "volume": 152907569,
    "routedVolume": 46943802,
    "marketShare": 0.02246,
    "isHalfday": 0,
    "litVolume": 35426666
  },
...

recent-stats

[
  {
    "date": "2017-01-11",
    "volume": 128048723,
    "routedVolume": 38314207,
    "marketShare": 0.01769,
    "isHalfday": false,
    "litVolume": 30520534
  },
...

in the first link the isHalfday value is a int (0/1) and in the recent it is a bool value.
this seems like the best fix is at the api level but it is yet to be seen if they will fix it, i will create an issue with iex and link to the issue in the comments.
