自動交易與指標 不對應?

指標有多次交易訊號，交易回測無安控，只有進場2次、出場1次強制1次?

指標

if open > close[1] then begin

plot1(open,"B1");

value1=open;

end else begin

if  high >= value1*1.005 then plot2 (high,"S1"); 

end;

交易

if position=0 and filled=0 and open > close[1] then setposition(1,open);

if position=1 and filled=1 and high >= value1*1.005 then setposition (0,high);
