把日K线组合为周K线,默认一周开始于周日(可调)。
使用方法: $.GetRecordsWeek(exchange)
$.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()); }template: strategy.tpl:40:21: executing "strategy.tpl" at <.api.GetStrategyListByName>: wrong number of args for GetStrategyListByName: want 7 got 6
