var0( 0 ) ;
var1( 0 ),<==";"是用來告訴PL該斷語法已經結束了，所以正確該是var(0),var1(0),
condition2 = Price > var0 and cross over var3 ;<== 這里少了Price..正確為condition2 = Price > var0 and Price cross over var3 ;
最後因為是訊號！所以以下都不能出現在訊號里..
if condition1 then
begin
var0 = WAverage( Price, Length1 ) ;
Plot1[Displace]( var0, "AvgWtd" ) ;
Plot2[Displace]( var3, "UpperBand" ) ;
Plot3[Displace]( var2, "LowerBand" ) ;
Plot4[Displace]( var0, "MidLine" ) ;<==(而且這里也少了end;正確為if ...then begin...end;)

因為你只有作多沒有作空
只有停損沒有停利
所以在低點進場作多之後就沒有符合的出場條件
以致於一直抱單不出
