碗型底

在型態學上，碗型底是一個可遇不可求的型態，這種碗如果夠大，後面多頭行情就可能走的愈長久，但可惜碗型底要用程式寫出來有點難度，我們試著寫出一個儘量接近的腳本，幫大家挑出可能的碗型底，但由於目標是寧可多挑也不要放過，所以挑中的標的，還需要大家用肉眼再作一次確認。

我們寫的腳本如下

複製
1input:t2(60,"敏感度(T)"),S1(true,"T=早訊號,F=晚訊號");
2variable:t1(1);
3value1=(H+L+O+C)/4;
4value2=square(H)+square(L)+square(O)+square(C);
5
6value14+=value2;
7if value2[t2]<>0 then value14-=value2[t2];
8value15+=value1;
9if value1[t2]<>0 then value15-=value1[t2];
10value16=(value14-t2*4*square(value15/t2))/(t2*4);
11
12value17=mtm(t2/2);
13value18=wma(value17,round(t2*0.2,0));
14value19=wma(value16,round(t2*0.2,0));
15
16condition1=s1 and value19<value19[1] and value18>value18[1];
17condition3=not s1 and value18 crosses over 0;
18if value18 crosses under 0 then condition2=true;
19if trueall(value19>value19[1] and value18<value18[1],t2*0.1) then condition4=true;
20if (condition1 or condition3) and condition2 and condition4
21then begin
22 condition2=false;
23 condition4=false;
24 ret=1;
25end;
input:t2(60,"敏感度(T)"),S1(true,"T=早訊號,F=晚訊號");
variable:t1(1);
value1=(H+L+O+C)/4;
value2=square(H)+square(L)+square(O)+square(C);

value14+=value2;
if value2[t2]<>0 then value14-=value2[t2];
value15+=value1;
if value1[t2]<>0 then value15-=value1[t2];
value16=(value14-t2*4*square(value15/t2))/(t2*4);

value17=mtm(t2/2);
value18=wma(value17,round(t2*0.2,0));
value19=wma(value16,round(t2*0.2,0));

condition1=s1 and value19<value19[1] and value18>value18[1];
condition3=not s1 and value18 crosses over 0;
if value18 crosses under 0 then condition2=true;
if trueall(value19>value19[1] and value18<value18[1],t2*0.1) then condition4=true;
if (condition1 or condition3) and condition2 and condition4
then begin
 condition2=false;
 condition4=false;
 ret=1;
end;

這個腳本在多頭市場下的回測報告如下

碗型底原本就可遇不可求，這個腳本把條件設的比較寬，挑中的要麻煩大家再檢視一下。
