今日最大成交量的抓法?

我想要抓取"今日"最大成交量的當根高低價區間

但是我只會寫出近X根K棒內的最大量的高低區間

如下

if highest(Volume[1],6) = Volume[1] then begin
if highest(open[1], 1) > highest(close[1], 1) then value11 = highest(open[1], 1) else value11 = highest(close[1], 1);
if lowest(open[1], 1) < lowest(close[1], 1) then value12 = lowest(open[1], 1) else value12 = lowest(close[1], 1);
end;

highest(Volume[1],6)的語法有什麼可以改?

//補-----------

if barfreq <> "MIN" and barinterval <> 5 then raiseruntimeerror("請使用5分鐘頻率"); 

if highest(Volume[1],6) = Volume[1] then begin 
if highest(open[1], 1) > highest(close[1], 1) then value11 = highest(open[1], 1) else value11 = highest(close[1], 1); 
if lowest(open[1], 1) < lowest(close[1], 1) then value12 = lowest(open[1], 1) else value12 = lowest(close[1], 1); 
end; 


if currenttime < 131500 and currenttime > 090500 then begin 
var:InCondition1(False); 
InCondition1 = close Crosses Above value11; 
if position = 0 and filled = 0 and InCondition1 then setposition(500/close,value11,label:="做多進場"); 
end; 

//-----------132450平倉----------- 
if filled <> 0 and currenttime > 132450 then setposition(0, market); 
//-----------出場-----------
input: profit_point(10, "停利(點)");
input: profit_drawback_point(5, "停利回跌(點)");
input: loss_point(10, "停損(點)");

var: long_condition(false);         { 進場買進作多 }
if profit_point = 0 then raiseruntimeerror("請設定停利(點)");
if profit_drawback_point = 0 then raiseruntimeerror("請設定停利回跌(點)");


if position > 0 and filled > 0 then begin 
    var: intrabarpersist max_profit_point(0);   { 啟動停利後最大獲利點 }

    if loss_point > 0 and Close <= FilledAvgPrice - loss_point then begin
        { 停損 }
        SetPosition(0);
        max_profit_point = 0;

    end else begin

        { 判斷是否要啟動停利 }
        if max_profit_point = 0 and Close >= FilledAvgPrice + profit_point then begin
            max_profit_point = Close;
        end;

        if max_profit_point <> 0 then begin       
            if Close <= max_profit_point - profit_drawback_point then begin
                { 停利 }
                SetPosition(0);
                max_profit_point = 0;
            end else if Close > max_profit_point then begin
                { 移動最大獲利點 }
                max_profit_point = Close;
            end;    
        end;        
    end;

end;

麻煩再幫我健檢一下這份

出現的問題是進場時間我希望是在090500~131500

不過也會有在這時間之外進場的

另外重點是我需要132450強制平倉

但在回測運行中也都沒有正確啟動

這部分也麻煩小幫手幫忙健檢一下
