일 K선을 주 K선으로 조합하여 주일이 일요일로 시작되는 것을 기본 설정합니다.

사용 방법: $.GetRecordsWeek (거래소)

$.GetRecordsWeek = function(exchange) {
    var rec1 = exchange.GetRecords(PERIOD_D1);
    if (!rec1) return null;
    if (rec1.length === 0) return [];
    var recN = [];
    var tmp = {
        Time: rec1[0].Time,
        Open: rec1[0].Open,
        High: rec1[0].High,
        Low: rec1[0].Low,
        Close: rec1[0].Close,
        Volume: rec1[0].Volume
    };
    for (var i = 1; i < rec1.length; i++) {
        if (Math.floor((rec1[i].Time / 86400000 - 3 - weekStarts + 1/3) / 7 + 1e-6) > Math.floor((rec1[i-1].Time / 86400000 - 3 - weekStarts - 1/3) / 7 + 1e-6)) { // new week
            recN.push({
                Time: tmp.Time,
                Open: tmp.Open,
                High: tmp.High,
                Low: tmp.Low,
                Close: tmp.Close,
                Volume: tmp.Volume
            });

            tmp.Volume = rec1[i].Volume;
        } else if (tmp.Time) { // same week
            tmp.High = Math.max(tmp.High, rec1[i].High);
            tmp.Low = Math.min(tmp.Low, rec1[i].Low);

        High: tmp.High,
        Low: tmp.Low,
        Close: tmp.Close,
        Volume: tmp.Volume
    });
    return recN;
};

function main() {
    var rec = $.GetRecordsWeek(exchange);
    Log(new Date(rec[rec.length-1].Time).toString());
