How to use custom API calls

[enriquepiatti]

Is possible to call for example this method?
https://binance-docs.github.io/apidocs/futures/en/#top-trader-long-short-ratio-positions
it works fine with a simple request like:
https://www.binance.com/futures/data/globalLongShortAccountRatio?symbol=BTCUSDT&period=5m

This work for me:

const getLongShortRatio = async (symbol) => {
    const url = 'https://fapi.binance.com/futures/data/globalLongShortAccountRatio';
    return new Promise((resolve, reject) => {
        binance.signedRequest(url, {symbol: 'BTCUSDT',period: '5m'}, (error, data) => {
            if (error) {
                reject(error);
            } else {
                resolve(data);
            }
        });
    });
