Hello,

Since I updated the changes after #13, I get a segmentation fault when running example.cpp. I narrowed down the cause to line 78: Websocket::enter_event_loop();
Had 0 problems before, so I'm positive it's since last update. Sometimes it happens instantly, sometimes it takes longer (10-20 seconds). So I'm guessing it happens in the do-while loop.

OS info:
System Version: macOS 10.14.6 (18G103)
Kernel Version: Darwin 18.7.0

Thank you for your time

I noticed that multiple streams are subscribed in the above way, not the combined streams. will this hit the limits of 10 incoming messages per second.

I get following error while trying to run the example:

[2019/04/01 20:23:07:5422] NOTICE: lws_protocol_init
[2019/04/01 20:23:07:8858] ERR: SSL connect error 337047686: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed
2019-04-01 20:23:07 885877 :binance::Websocket::event_cb LWS_CALLBACK_CLIENT_CONNECTION_ERROR

Any idea?

hi, is it possible to subscribe and parse different streams at the same time ? if so, can you provide with an example if possible ? Also, do you think it's safe to multi-thread ? My aim is to open one many streams per symbol and pipe the data through a local socket to another module. Thanks !

Hi Dmikushin.
Thanks for your project.
I would like to know if you have the c++ code for place a new order using Lotsize , I have seen your function binance::Market::getLotSize, but I wold like to know if you have the implementation using this function + Rules of StepSize ?

Thanks for your help.
Best Regards Maria.

Hi,
almost got it compiled on osx 10.13.6.

• osx does not have HOST_NAME_MAX in limits.h (dont know where it is, just set it to 512 locally)
• osx does not have a pthread_self() that returns int (it returns a struct) (binance_websocket.cpp line 63). This can be fixed using this code snippet in the same place:

uint64_t tid;
pthread_threadid_np(NULL, &tid);
return tid;

then code compiles. There seems to be a problem with jsoncpp though. cause the last stepp in compiling libbinacpp.so gives me this error:

if i remove -ljsoncpp there are tons of errors, so it clearly finds jsoncpp. I have no idea what the issue is. Any help appreciated.
(compiles fine on linux ! thanks for the effort)

Hi guys,

i have an issue with placing a market order. Especially with the timeforce.
I get this message when trying to : "Parameter 'timeInForce' sent when not required."

Do you know how can i fix it ?
thanks

Currently we have access to spot data which is available at 'stream.binance.com'. Can we access futures data also which is available at fstream.binance.com? Simply changing BINANCE_WS_HOST to fstream.binance.com doesn't work. Has anyone else tried accessing futures data using binance-cxx-api?

Hello
I tested this library and python one
When call the same restful API ， this library costs 800ms and python library only cost 300ms . Is there any way to imporve the performance？ Is the problem with keep alive？
Thanks

Hi,

I'm sure you will be glad to know there is another, better and more complete implementation of Binance API on C++: https://github.com/niXman/binapi

I will be grateful for advertising! =)

I have a strange issue here, almost after 24 hours of running my program using

Websocket::enter_event_loop()

I do not receive any more "wsi scheduling validity check" in program syslogs.
Therefore the program does not get any update from Binance ticker which I set-up.
I was wondering if anyone else has this kind of behavior.

Hello,

I compiled everything and can use the REST functions without issues, but I'm struggling to find a solution to getting the websocket examples to work.

Without changing the original code, the connection fails with lws_ssl_client_connect1.
If I add LCCSCF_ALLOW_INSECURE, there are no errors, but no data is received.

Any ideas on how can I debug/fix it?

Hello,

When following the installation instructions of this library, executing the cmd "cmake .." in the build directory causes the following error:

CMake Error at CMakeLists.txt:31 (target_link_libraries):
Cannot specify link libraries for target "mbedcrypto::mbedcrypto" which is
not built by this project.

Do I need to install mbedcrypto separately, and if so wich one? Because there are multiple mbedcrypto git repos.
(Thank you for your time)

I am getting Segmentation Fault, just by executing "account.getInfo(json_result, recvWindow)"

Program received signal SIGSEGV, Segmentation fault.

git clone https://github.com/dmikushin/binance-cxx-api.git
cd binance-cxx-api
mkdir build
cd build/
cmake ..
./example

After cmake ..
I did not find an example under build directory.

./example
won't run.

Did you miss any command? Thanks.

Best.
