[ahab1b]

I just started using this so I am working through the examples. when I run the following code, I get Fatal error: Uncaught Error: Call to undefined method Binance\API::kline()

Platform:

• windows

php version:

• 7.1

code

$api->kline(["BTCUSDT", "EOSBTC"], "5m", function($api, $symbol, $chart) {
    var_dump( $chart );
    //echo "{$symbol} ({$interval}) candlestick update\n";
    $interval = $chart->i;
    $tick = $chart->t;
    $open = $chart->o;
    $high = $chart->h;
    $low = $chart->l;
    $close = $chart->c;
    $volume = $chart->q; // +trades buyVolume assetVolume makerVolume
    echo "{$symbol} price: {$close}\t volume: {$volume}\n";

    $endpoint = strtolower( $symbol ) . '@kline_' . "5m";
    $api->terminate( $endpoint );
});

thank you

This sounds like an issue with composer. I ran in to the same problem until I managed to get composer installed and working
