24時間間の恒久契約の価格変化の情報を入手した後,結果から価格変化の幅 (priceChangePercent) を最大に獲得した前数契約の取引はどうだったのでしょうか?
実験結果として,
[{"lastPrice":"58131.80","lowPrice":"56812.00","closeTime":1617193588048,"lastId":657590646,"priceChangePercent":"-1.725","quoteVolume":"16870412679.78","volume":"287984.541","openTime":1617107160000,"weightedAvgPrice":"58580.97","lastQty":"0.004","openPrice":"59152.17","highPrice":"59920.00","firstId":654550517,"count":3040076,"symbol":"BTCUSDT","priceChange":"-1020.37"},{"priceChange":"-30.38","priceChangePercent":"-1.648","closeTime":1617193587663,"symbol":"ETHUSDT","quoteVolume":"3758616198.20","weightedAvgPrice":"1829.43","lastPrice":"1813.36","highPrice":"1867.00","volume":"2054532.966","lastQty":"9.445","openPrice":"1843.74","lowPrice":"1771.85","openTime":1617107160000,"firstId":430017156,"lastId":431621119,"count":1603915}......]
function compare(property) {
return function(obj1, obj2) {
var value1 = obj1[property];
var value2 = obj2[property];
return value2 - value1; // 降序排列
}
}
function main{
exchange.IO("api", "GET","/fapi/v1/ticker/24hr").sort(compare("priceChangePercent"));
}
得到的结果是按照价格变动从大到小排列的
