logon -u UserId
Send a request to logon with the UserId passed in argument.

Create an object to display the OrderBook
separating Ask
and Bid
:
Table
: object to display column and row with Price
and Quantity
dynamically.Create a Selector
to choose between any OrderBook
available server side.
Add the documentation over the whole project.
Reference all the advancement on the document with the pull request in the comment under this issue.
Create unit or functional test for the whole solution, targeting in priority the crucial part.
Add to the interface a section to cancel Order
place by the client:
NumericInput
): of the Order
to cancel.Button
): action to save and send the cancel to the server.Add the document for each pipeline (refered with the namespace pip
) and the core Pipeline
.
Create a Pipeline
to handle every error send over the whole solution and send them to the OutNetwork
.
The header of any fix
request is verify only by the function fix::Header::Verify
, but it doesn't verify the actual value of the different field.
Verfiy this field:
TargetCompId
: verify that's the one of the user or the one of the serverSenderCompId
: same as TargetCompId
BodyLenght
: compare it to the actual body lenght receivedCheckSum
: verify it's match the calculated one on the requestWhen adding a bid when taking their is an higher ask, it never sell.
Because we use a template function (add<T>
) to manage the OrderBook
bid and ask, the condition when exiting the while is wrong when the order type is Ask
:
for (auto &[_key, _val] : _book) {
if (_key > _price) // this condition is wrong
break;
OrderList &ol = _book.at(_key);
Full code here
The actual reason of this behavior is because we use 2 differents sorting algorithm for BidBook
and AskBook
:
using AskBook = std::map<Price, OrderList, std::greater<Price>>;
using BidBook = std::map<Price, OrderList, std::less<Price>>;

Manage the UDP
connection to receive and send request and connect them to the UI.
Being able to set the name of any std::thread
contained by ThreadPool
.
Add to the interface a section to send Order
with this elements:
Selector
): choose between Ask
or Bid
.NumericInput
): quantity of the order.NumericInput
): quantity of the order.Button
): action to save and send the Order
to the server.It will display a small text to signal error
Implementation of the 2 UDP pipeline
, to broadcast change on the OrderBook
:
UDP input
: let any socket to connect to the server, when a message is receive disconnect then client.UDP output
: broadcast the change on the OrderBook
to every client connected via the UDP input
The format of the data send need to be determined
Management of the FIX protocol action:
Logon
(A):Logout
(5):NewOrder
(D):OrderCancelReplaceRequest
(G):OrderCancelRequest
(9):The different action need a global and short description and could change some pipeline behavior
When a c::Socket
or an abstraction (net::Socket
, net::tcp::Socket
, net::Acceptor<T>
,...) is close by any way (from the connected service or by the actual solution), the programme crash with a:
Segmentation fault (core dumped)
Make the server able to manage multiple OrderBook
and Action
pipeline.
The server is think to allow this with minimum impact on other pipeline behavior.
Make an interface to modify an Order
made by the user:
NumericInput
): target the OrderId
.NumericInput
): new Quantity
to set.NumericInput
): new Price
to set.Button
): action to save and send the Order
modification to the server.Create interface object using SFML
to simplify the develepoment:
Button
: simple button taking a sf::Texture
or a std::string
to be display, triggering a callback function.Selector
: multiple choice selector.Input
: a box where you can input any type of character.NumericInput
: an input taking only numeric input.AlphaInput
: an input taking only alphabetic input.
NumericInput
andAlphaInput
should be based onInput
Management of the FIX protocol action:
ExecutionReport
(8):MarketDataSnapshotFullRefresh
(W):MarketDataIncrementalRefresh
(X):The different action need a global and short description and could change some pipeline behavior
The Market
must order action or the OrderBook
due of the multithreading on previous the pipelines (Serializer
, Action
) with the seqNum
from the FIX
protocol.
Use an std::queue
to store action with a seqNum
higher than the actual Market
seqNum await.
Create more micromanagement on the status of each Pipeline
in the main thread.
Connect a client
--> LOGON
---> NEW ORDER
---> WAIT FOR CLIENT 2 ORDER FILL
---> TEST FAIL -> SOCKET.CLOSE() without LOGOUT
CLIENT 2 --> LOGON ---> NEW ORDER --> LOGOUT
CLIENT 2 --> BLOCKED at sending logout
--> Cannot send / connect to the server anymore
HOW TO REPRODUCE:
BLOCKING_TEST.py
BLOCKING_TEST2.py
Test every functionnality of the OrderBook
.
Create unit test on the fix::Message
serializer and deserializer using gtest
Manage the TCP
connection to receive and send request (certainly implementing the system of Pipeline
?) and connect them to the UI.
Verify each log to detail the behavior of the whole solution.
Fix all warning on the whole solution (mostly error handling return).
