日K線を週K線に組み合わせると,デフォルトで週が日曜日から始まる (調整可能).
使用方法: $.GetRecordsWeek (交換)
$.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.Time = rec1[i].Time;
tmp.Open = rec1[i].Open;
tmp.High = rec1[i].High;
tmp.Low = rec1[i].Low;
tmp.Close = rec1[i].Close;
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);
tmp.Close = rec1[i].Close;
tmp.Volume += rec1[i].Volume;
}
}
recN.push({
Time: tmp.Time,
Open: tmp.Open,
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());
}
スネークイユ4時間のK線ならどうする?
ロガありがとうございました
