You can see it here between two good klines. Didn't happen with python-binance so i thought that might be library issue.
Json above is formed by doing multiple requests so in this case it's not last in the list.

Hello, I'm getting this weird error when trying to compile:

unresolved external symbol "public: class Json::Value __cdecl FuturesClient<class FuturesClientUSDT>::change_leverage(struct Params const *)" (?change_leverage@?$FuturesClient@VFuturesClientUSDT@@@@QEAA?AVValue@Json@@PEBUParams@@@Z)

My code:

std::string api_key{ "" };
std::string api_secret{ "" };

static FuturesClientUSDT my_client{ api_key, api_secret };
	
Params leverage_params{};
leverage_params.set_param("symbol", std::string(coin_name + "USDT"));
leverage_params.set_param("marginType", std::string("ISOLATED"));

std::cout << my_client.change_leverage(&leverage_params) << std::endl;

What am I doing wrong?

Best Regards.

How would one get the currnet price of a symbol in a loop to compare it?
im not sure how to read the json from get_ticker

Getting

error LNK2019: unresolved external symbol "public: void __cdecl Params::set_param<class std::basic_string<char,struct std::char_traits,class std::allocator > *>(class std::basic_string<char,struct std::char_traits,class std::allocator > const &,class std::basic_string<char,struct std::char_traits,class std::allocator > * &&)" (??$set_param@PEAV?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@std@@@params@@QEAAXAEBV?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@std@@$$QEAPEAV12@@z) referenced in function "public: class TickerData __cdecl Binance::getKlines(class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >,class std::basic_string<char,struct std::char_traits,class std::allocator >)" (?getKlines@Binance@@qeaa?AVTickerData@@v?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@std@@000@Z)

On simplest code

TickerData GetKlines(std::string symbol, std::string interval, std::string startTime, std::string endTime)
{
        Params requestParams;
        requestParams.set_param("symbol", symbol);
        requestParams.set_param("interval", interval);
        return TickerData();
}

All .cpp files of the library are included along the program.

Hello, I've been wondering how can you create a user data listen stream?

There is no example and quite didn't understand the code.

What I came up to (but doesn't compile neither works):

SomeFunctor ws_stream_read{};
std::string cust_stream = "fapi/v1/listenKey";
std::thread t1(&FuturesClientUSDT::stream_userStream<SomeFunctor>, cust_stream, std::ref(ws_stream_read.msg_buffer), std::ref(ws_stream_read));
t1.join();

Any ideas?

Best Regards.
