Enhanced System Tester

Matthew大師,

 

喺呢度搵左好耐，好辛苦學寫左少少 ，請教點寫:

在Enhanced System Tester,

買入: Cross(mov(close,10,s), mov(close,20,s))
沽出: Cross(mov(close,20,s), mov(close,10,s))

在每天10:00am to 10:15am及12:30pm和16:30pm忽略(即不發出)買入/沽出signal

在12:29pm及16:29pm平倉底

 

BUY ORDER:

Cross(mov(close,10,s), mov(close,20,s))

 

SELL ORDER:

Hour()=12 and Minute()=29
or
Hour()=16 and Minute()=29

 

SELL SHORT ORDER:

Cross(mov(close,20,s), mov(close,10,s))

 

BUY TO COVER ORDER:

Hour()=12 and Minute()=29
or
Hour()=16 and Minute()=29

(在每天10:00am to 10:15am及12:30pm和16:30pm忽略(即不發出)買入/沽出signal)應該點寫/加在那兒?

以上有錯請指教

謝過Matthew大師

 太過複雜了, 會有很多問題須要解決 ~

如真的要做到, 你可以試下這樣:

BUY ORDER:
buyinfo1:=Cross(mov(close,10,s), mov(close,20,s)) ;
info1:= Hour()<=10 ;
info2:= Hour()=10 and Minute()>15;
info3:= Hour()=12 and Minute()<30;
info4:= Hour()=16 and Minute()<30;

 

if(buyinfo1 and info4,1,
if(buyinfo1 and info3,1,
if(buyinfo1 and info2,1,
if(buyinfo1 and info1,1,0

))))

 

其它你自己執下佢 ~

謝過Matthew大師and大大師兄! 比左我好多啟示!

1)是否所有時段都要有定義?可否只定義不出buy/sell signal時段=0, else=1?

2)if()裏面可否有多個"and"?
3)請問當中是否1=出buy signal, 0=不出buy signal?

4)在索引找不到"buyinfo" 及":=" command是什麼意思?可在那兒找的?

1) 要睇你如何運用

2) 可以

3) 正確 src="http://www.bp-system.com/discuz/images/smilies/yang/A_100.gif" border=0 smilieid="286">

4) 自定義變數值

於 help 中  Operator Precedence 內有:
Parentheses were used in manyof the preceding formulas in this chapter to control the operation precedence (the order in which the operators are calculated). MetaStock always does operations within the innermost parentheses first.
When parentheses are not used, the precedence is as follows:
- Negative values
* Multiplication
/ Division
+ Addition
- Subtraction
< Less than
> Greater than
<= Less than or equal to
>= Greater than or equal to
= Equal to
<> Not equal to
And Logical "And"
Or Logical "Or"
:= Variable assignment operator

The expression "H + L / 2" (without parenthesis) would be calculated by MetaStock as "L / 2" plus "H," since division has a higher precedence. This would result in a much different value than "(H + L) / 2."

For ease of reading, we recommend that you always use parenthesis to control precedence.

複雜死人!
簡單d，咁只要
1)在12:30pm和16:30pm忽略(即不發出)買入/沽出signal應該點寫 / 加在那兒?
2)在12:30pm和16:30pm平倉底

煩請指教!
謝過Matthew大師and大大師兄!

試下

BUY:

buyinfo1:=Cross(mov(close,10,s), mov(close,20,s)) ;

info1:= Hour()=12 and Minute()<29;
info2:= Hour()=16 and Minute()<29;

if(buyinfo1 and info2,1,
if(buyinfo1 and info1,1,0

)
)

 

Sell:
Hour()=12 and Minute()=29
or
Hour()=16 and Minute()=29

又比左我好多啟示! 謝過Matthew大師and大大師兄!

Matthew大師,

我發現 Hour()=16 and Minute()=29 {這個等於16:00 及所有29分}

點先可以指定16:29這刻?

無問題喎 ~

Matthew大師早晨,

當set左止賺/止蝕後，出來的結果:
當某一bar(e.g.10:32)的高/低位到達或超越果一bar的入市價(以close計)的止賺/止蝕後(e.g.10pts)，
system會在果個時間出止賺/止蝕! (見圖)

(A)果bar當時無出止賺，但(B)果bar因低位到達或超越止賺位(e.g.10pts)，即時(e.g.10:32)出左止賺!

我係唔係有d地方未set好?
