Sample Binance API queries
Getting All Isolated Margin Symbols in PHP:
$api_key = "*****";
$secret = "*****";
$opt = [
"http" => [
"method" => "GET",
"header" => "User-Agent: Mozilla/4.0 (compatible; PHP Binance API)\r\nX-MBX-APIKEY: {$api_key}\r\n"
]
];
$context = stream_context_create($opt);
$params['timestamp'] = number_format(microtime(true)*1000,0,'.','');
$query = http_build_query($params, '', '&');
$signature = hash_hmac('sha256', $query, $secret);
$endpoint = "https://api.binance.com/sapi/v1/margin/isolated/allPairs?{$query}&signature={$signature}";
$res = file_get_contents($endpoint, false, $context);
echo $res;
My first experiment with a peak detection algorithm
Hi guys!
For those how are interested in what I am doing now I provided my app screenshots with ‘Find Peaks’ button that runs ZScore algorithm on a cryptocurrency market data (follow the this link for the algorithm source code in C++).
Honestly I am not quite enough understand yet how it works, because I run it first time today, but at least there is some correlation between input parameters and the results. The lesser the threshold and the longer the lag the lesser peaks are found. Increasing the influence also reduces the peak count.

Setting up Ethereum node on Windows 10 and Ubuntu.
After a few attempts I was able to start Ethereum Mist 0.11.1 in ‘fast’ mode on Windows 10:
it downloaded ‘geth’, connected to {“path”:”\\\\.\\pipe\\geth.ipc”} and started to sync, but when sync finished I was unable to send transactions (they were ‘denied’ for some reason).
