Binance is returning the error "Filter failure: PERCENT_PRICE" when sending an order.
We checked on their documentation and the issue is the max allowance for decimal places in your order prices and sizes

Is anyone else having this same issue?
The issue is in "BinaCPP::send_order" when building the post to send the order, the price and size are being converted to string using to_string.... but no way to control the decimal places in there.

I am running a calculation with 3 prices using the get_depth() function.

When i get the result i want a function is called, that uses 3 send_order() functions.

However after the call of send_order() i get

<"BinaCPP::curl_api> curl_easy_perform() failed: Failed initialization
and the get_depth functions also don't work.

Any Idea why that is?

hello,

I got some link errors. I put all binance related .h and .cpp files in the same directory as example.cpp (to resolve some errors related to to_string was not declared in this scope)

修正方法：
CURLOPT_WRITEDATA这个选项在C++中使用时就要注意了，
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WRITEDATA, void *pointer);
这里pointer必须是struct，不能是类class，否则会有莫名奇怪的错误
这样的后果是，最后下载的文件长度与原有长度不符，使用md5sum计算得到的校验值与标准值不符。这证明是错误的文件

Dear Sir, I have lots of questions as new guys.
Q1: I use"cmd->path->nmake" to make MAKEFILE compile with GUN Compiler， use VS2010 to compile .cpp and .h documents, am I right ?
Q2: could you tell me which softwares to finish this project?
May I send my question to your email for help. thank you very much!!

Sir, my computer has W7 (32bit) and ubuntu 12.04 (32bit). But libcurl.a .so and libwebsockets.a .so documents you supplied is 64 bit. I cound not recompile them except others. May I beg you to send me the 32 bit .a and .so document ? thank you very much! email: [email protected]

Pretty much the title. I got rasbian on raspberry pi.
i installed libcurl4-openssl-dev and libwebsockets-dev with the apt-get command.

now i included the libraries and header into the makefile looking like this:

Can you help me ?

This project's Makefile depends on specific version of libraries. For Binance's official C++ API this is pretty questionable. Should be a CMakeLists.txt that accepts a range of library versions and not use precompiled libraries included in the repo, but the libraries on the user's machine. Maybe Binance can have a contest awarding BNB for a community member to make the build process more robust if they want to see more adoption of this library.

Hello,

Is it possible to compile this code using Qt 5 under Linux?
An example would be helpful.

Thanks

This C++ API is slower than other Binance interfaces (python-binance) because of the poor performance of libcurl. I timed reading the ticker/allBookTicker endpoint from two small programs in both C++ (with this API) and python (using python-binance):

#include <chrono>
#include <cstdio>
#include <json/json.h>
#include "binacpp.h"

int main(int argc, char** argv) {
    std::string api_key = "";
    std::string api_secret = "";
    BinaCPP::init(api_key, api_secret);

    auto time_start = std::chrono::high_resolution_clock::now();

    Json::Value result;
    BinaCPP::get_allBookTickers( result );

    auto time_end = std::chrono::high_resolution_clock::now();
    auto time_elapsed = time_end - time_start

    double time = std::chrono::duration_cast<std::chrono::microseconds>(time_elapsed).count() / 1000000.0;
    printf("%f\n", time);

    return 0;
}

from time import time
from binance.client import Client

client = Client('', '')

time_start = time()
client.get_orderbook_tickers()
time_end = time()

print(time_end - time_start)

The Python example grabs the data almost always 3-4x faster than the C++ code, with the Python code running in about 200ms and the C++ version taking ~800ms. This line, calling out to the libcurl API, is the slowest part of the binacpp library function. Why is libcurl so much slower here than the Python requests package?

Hi
the example provided runs fine however, when trying to make it from the makefile provide, I get this error:
openssl/ssl.h not found

I installed ssl band added these lines in the makefile:

libssl_dir=../../openssl-1.0.0t
libssl_include=${libssl_dir}/include
libssl_lib=${libssl_dir}/lib

and -I$(libssl_include)
as well as -L$(libssl_lib) \

but then I get -lcrypto not found

Any idea on how I can rebuild the example properly?

BinaCPP::curl_api_with_header calls curl_global_init which raises an exception (SIGSEGV segmentation)

/** code **/
BinaCPP::curl_api_with_header( string &url, string &str_result, vector &extra_http_header , string &post_data , string &action )
{
BinaCPP_logger::write_log( "BinaCPP::curl_api" ) ;

CURL *curl;
CURLcode res;

curl_global_init(CURL_GLOBAL_DEFAULT);

/** end code ****/

If someone knows how to get around this one, Please let me know

Thanks!

Hi,

Sorry , I am new to this and curl/ websocket/openssl.
When I run the example_userStream.cpp, i met the problem:

�[0m�[31;1m[2018/01/16 18:41:32:4003] ERR: SSL error: unable to get local issuer
certificate (preverify_ok=0;err=20;depth=1)

and there is no call back event received.

Could you indicate where the problem is?

Thanks,
Frank

Hi.
I have a problem at moment to compile after of the new update.
i get this error of the archive binacpp.cpp

binacpp.cpp:228:39: error: ‘to_string’ was not declared in this scope
querystring.append( to_string( limit ) );

binacpp.cpp: In static member function ‘static void BinaCPP::get_aggTrades(const char*, int, time_t, time_t, int, Json::Value&)’:

binacpp.cpp:296:44: error: ‘to_string’ was not declared in this scope
querystring.append( to_string( startTime ) );
^
binacpp.cpp:303:41: error: ‘to_string’ was not declared in this scope
querystring.append( to_string( fromId ) );
^
and follow...haha

I see in commits that they deleted a function associated with "to_string" ("static std::string to_string(double val)" and "inline string to_string (const T& t)") in the new update. Could that be the cause of the problem?

Hi, I downloaded the project and wanted to try the examples, but the terminal sais: /usr/bin/ld: cannot find -ljsoncpp. What can I do?

how to build the libraries and api on windows with mingw

The provided library doesn't work with i686-posix-dwarf, MinGW-W64 version 6.1.0 or it is missing linker dependencies other than listed here. The library is impossible to build because of the unknown dependencies. Would you be kind enough to provide information and flags you used to build LibWebSockets?

I always get this error for libcurl and websockets.. I don't know much about compilers and linkers (tried a lot of different g++ commands but no avail, always stuck somewhere, also tried installing libcurl and websockets etc and not linking them locally) Help would be greatly appreciated :)

Is binacpp, and if not, could it be installed via vcpkg?

It would be much more tempting to test it if I could install as follows:
vcpkg install binacpp

I get an error when I try to make a market trade using the example,

long recvWindow = 10000;
Json::Value result;
BinaCPP::send_order( "BNBETH", "BUY", "MARKET", "GTC", 20 , 0,   "",0,0, recvWindow, result );

The output of result is:

"code" : -1106,
"msg" : "Parameter 'timeInForce' sent when not required."

I have tried to change the timeInForce to each available one but it doesn't work. If I remove it completely, I get this error:

"code" : -1105,
"msg" : "Parameter 'timeInForce' was was empty."

I have managed to make limit orders but have yet been able to make a market order. Any idea what is wrong?

As a side note, is it possible to make orders using 100% of the available asset?

I want the robot to check the inventory of a cryptographer in Binance, not to buy if it is less than X, and if it is more than D.
Thankful

I've finally got this compiled for Windows(as a static library, mind you). Yay me! This request should be platform independent, though.

In regards to dependencies, it could help others if you state that curl needs to be compiled with zlib support.

Thank you!

Hello,

i have to modify the source to call a member variable (a pointer of an external class which i addet as additional parameter to the constructor of the websocket class) from the static event_cb function.
Is there any way to make the event_cb non static in the class?

cd src
make

Outputs :

Arch linux, with libcurl and libwebsockets already installed from AUR (matching versions).

I have this problem BinaCPP::get_depth Segmentation fault.
My code is:
Json::Value resulta;
BinaCPP::get_depth( "NCASHETH", 5, resulta ) ;
cout << resulta << endl;

I get:
2018-03-10 21:03:32 936921 :BinaCPP::get_depth
Segmentation fault

I got the same problem with BinaCPP::get_order().

I do not know if it's a bug or it's a problem of mine, but the other functions , BinaCPP::get_price() and BinaCPP::get_24hr() work fine for me. The others that I have not tried yet.
I use these library versions and I compile in linux 64bit:
-libcurl 7.47
-libwebsockets-2.4.2
-jsoncpp-1.8.4

Hi,
I'm using this code:

 BinaCPP_websocket::init();
 BinaCPP_websocket::connect_endpoint(ws_depth_onData ,"/ws/!bookTicker"); 
 BinaCPP_websocket::enter_event_loop(); 

That's the error I get:
[2021/05/14 22:28:31:3827] N: LWS: 4.1.6-, loglevel 7
[2021/05/14 22:28:31:3838] N: NET CLI SRV H1 H2 WS IPV6-on
[2021/05/14 22:28:32:0550] E: SSL error: unable to get local issuer certificate (preverify_ok=0;err=20;depth=1)

Any ideas why?

I want get order book and tickers at the same.

When I start functions in different thread, Application Crashed.

Pretty much the Title. When compiling i get the error

Call of overloaded 'to_string(double&)* is ambiguos'

from binacpp.h.

Using Win64 and Codeblocks.

Any suggestions?

Having :

/usr/bin/ld: cannot find -ljsoncpp
collect2: error: ld returned 1 exit status
make: *** [Makefile:26: example] Error 1

while making example

who to fix that ? Any ideas ?

hi,

just for your information: https://github.com/niXman/binapi

the list of implemented API you can see here: https://github.com/niXman/binapi/blob/master/include/binapi/api.hpp

all the API functions provide both synchronous and asynchronous way.

data types are strongly typed in the form of structures, no generic types like Json are used!

When I tried to use "make example" command, it appers that I have a problem with ldmisc (Don't know what is it?)

Hi , is there any implementation for generating signatures with ed25519 keys in C++. I have been trying to implement one unsuccessfully for sometime.
Thanks.

SIGSEV from JSON parsers.

After rebuild examples, SIGSEV stops the program. It stemmed from the _M_replace function in the libstdc++.so.6.

please see the image below from nemivers

Is there any way to remove this error?

get_current_ms_epoch() function return stupid unsigned long.

if back to readable format , that show 2055/../..

at here;
