請問，在交易腳本中"指定"交易時間，台指夜盤交易時間下午3點半~凌晨3點半，要怎麼加入語法?

// 宣告參數

input: Length(9, "計算期數"), RSVt(3, "RSVt權數"), Kt(3, "Kt權數"), LowBound(40, "低檔區"), HighBound(75, "高檔區"), 

       profit_point(20, "停利(點)"), loss_point(20, "停損(點)");

variable: _rsv(0), _k(0), _d(0);

// 資料讀取筆數設定

SetTotalBar(maxlist(Length,6) * 3 + 8);

Stochastic(Length, RSVt, Kt, _rsv, _k, _d);

// 多方進場策略：K在低檔區由下往上突破D值。出場策略：K由上往下穿越D值。

if _k < LowBound and _k crosses above _d   

and filled = 0 and position = 0 then setposition(1, market);

{多單停損停利(點)}

if filled = 1 and position = 1 and (high >= (filledAvgPrice + profit_point){停利} 

or low <= (filledAvgPrice - loss_point){停損}) 

then setposition(0, market);
