語法?[Syntax]
代碼格式
空格建、Tab鍵、換行鍵和換頁符都可以成為代碼排版的分隔符，你能使用各種符號來增加代碼的可讀性。

注釋?
多行注釋使用?/*?作為開始到?*/?結束，在這之間不能夠嵌套。單行注釋使用?//?作為開始到新的一行結束，可以被嵌套到多行注釋之中。
示例:
//?單行注釋?
/*?多行
?????注釋?//?嵌套的單行注釋?
注釋結束?*/

標識符?
標識符用來給變量、函數和數據類型進行命名，長度不能超過31個字節
你可以使用數字0-9、拉丁字母大寫A-Z和小寫a-z(大小寫有區分的)還有下劃線(_)。此外首字母不可以是數字，標識符不能和保留字沖突.
示例:
//?NAME1?namel?Total_5?Paper

保留字?
下面列出的是固定的保留字。不能使用以下任何保留字進行命名。?

數據類型?[Data?types]
數據類型概述
主要數據類型有:
? Integer?(int)?
? Boolean?(bool)?
? ?èò?eà???(char)?
? String?(string)?
? Floating-point?number?(double)?
? Color?(color)?
? Datetime?(datetime)?
我們用Integer類型數據來作為DateTime和Color數據的存儲。
使用以下方式可以進行類型站換:
int?(bool,color,datetime);
double;
string;

Integer?類型
十進制:?數字0-9;0不能作為第一個字母
示例:
12,?111,?-956?1007
十六進制:?數字0-9;拉丁字母a-f或A-F用來表示10-15;使用0x或者0X作為開始。
示例:
0x0A,?0x12,?0X12,?0x2f,?0xA3,?0Xa3,?0X7C7
Integer?變量的取值范圍為-2147483648到2147483647。

Literal?類型
任意在單引號中的字符或十六進制的任意ASCII碼例如'\x10'都是被看作為一個字符，
一些字符例如單引號('),雙引號("),問號(?),反斜杠(\)和一些控制符都需要在之前加一個反斜杠(\)進行轉意后表示出來：
line?feed?NL?(LF)?\n
horizontal?tab?HT?\t
carriage?return?CR?\r
reverse?slash?\?\\
single?quote?'?\'
double?quote?"?\"
hexadecimal?ASCII-code?hh?\xhh
以上字符如果不經過反斜杠進行轉意將不能被使用
示例:
int?a?=?'A';
int?b?=?'$';
int?c?=?'?';?//?code?0xA9
int?d?=?'\xAE';?//?symbol?code??

Boolean?類型
Boolean?用來表示?是?和?否,?還可以用數字?1?和?0?進行表示。True和Flase可以忽略大小寫。
示例:
bool?a?=?true;
bool?b?=?false;
bool?c?=?1;

Floating-point?number?類型
浮點型變量在整數型后面加一個點(.)用來更精確的表示十進制數字。
示例:
double?a?=?12.111;
double?b?=?-956.1007;
double?c?=?0.0001;
double?d?=?16;
浮點型的取值范圍從?2.2e-308?到?1.8e308.

String?類型
字符串型是用來表示連續的ASCII碼字符的使用連續的兩個雙引號來包括需要表示的內容如："Character?constant".
示例:
"This?is?a?character?string"
"Copyright?symbol?\t\xA9"
"this?line?with?LF?symbol?\n"
"A"?"1234567890"?"0"?"$"

Color?類型
顏色類型可以使用以下示例里的幾種方式進行定義。?
示例:
//?symbol?constants
C'128,128,128'?//?gray
C'0x00,0x00,0xFF'?//?blue
//?named?color
Red
Yellow
Black
//?integer-valued?representation
0xFFFFFF?//?white
16777215?//?white
0x008000?//?green
32768?//?green

Datetime?類型
時間類型使用年、月、日、時、分、秒來進行定義，你可以使用以下示例中的方式來定義變量。
示例:
D'2004.01.01?00:00'?//?New?Year
D'1980.07.19?12:30:27'
D'19.07.1980?12:30:27'
D'19.07.1980?12'?//equal?to?D'1980.07.19?12:00:00'
D'01.01.2004'?//equal?to?D'01.01.2004?00:00:00'
D'12:30:27'?//equal?to?D'[compilation?date]?12:30:27'
D''?//equal?to?D'[compilation?date]?00:00:00'
運算符和表達式?[Operations?&?Expressions]
表達式
一個表達式可以擁有多個字符和操作符，一個表達式可以寫在幾行里面。
示例:
a++;?b?=?10;?x?=?(y*z)/w;
注:分號(;)是表達式的結束符。

算術運算符
Sum?of?values?i?=?j?+?2;
Difference?of?values?i?=?j?-?3;
Changing?the?operation?sign?x?=?-?x;
Product?of?values?z?=?3?*?x;
Division?quotient?i?=?j?/?5;
Division?remainder?minutes?=?time?%?60;
Adding?1?to?the?variable?value?i++;
Subtracting?1?from?the?variable?value?k--;
加減1的運算符不能被嵌套在表達式中
int?a=3;
a++;?//?可行的表達式
int?b=(a++)*3;?//?不可行的表達式

賦值運算符
注:將右側的結果賦值給左側的變量
將x的值賦值給y?y?=?x;
將x的值加到y上面?y?+=?x;
在y上面減去x的值?y?-=?x;
得到y的x倍的值?y?*=?x;
得到y除以x的值?y?/=?x;
取y除以x后的余數?y?%=?x;
y向右位移x位?y?>>=?x;
y向左位移x位?y?<<=?x;
得到邏輯AND的值?y?&=?x;
得到邏輯OR的值?y?|=?x;
得到邏輯非OR的值?y?^=?x;
注:一個表達式只能有一個賦值運算符.

關系運算符
用返回0(False)或1(True)來表示兩個量之間的關系。
a是否等于b?a?==?b;
a是否不等于b?a?!=?b;
a是否小于b?a?<?b;
a是否大于b?a?>?b;
a是否小于等于b?a?<=?b;
a是否大于等于b?a?>=?b;

真假運算符
否定運算符(!),用來表示真假的反面的結果。
//?如果a不是真的
if(!a)
Print("not?'a'");
邏輯運算符或(||)用來表示兩個表達式只要有一個成立即可。
示例:
if(xl)
Print("out?of?range");
邏輯運算符和(&&)用來表示兩個表達式要同時成立才行。
示例:
if(p!=x?&&?p>y)
Print("true");
n++;

位邏輯運算符
~?運算符對操作數執行按位求補操作。
b?=?~n;
>>?運算符對操作數執行向右位移操作。
x?=?x?>>?y;
<<?運算符對操作數執行向左位移操作。
x?=?x?<<?y;
一元?&?運算符返回操作數的地址
為整型和?bool?類型預定義了二進制?&?運算符。對于整型，&?計算操作數的按位“與”。對于?bool?操作數，&?計算操作數的邏輯“與”；也就是說，當且僅當兩個操作數均為?true?時，其結果才為?true。
b?=?((x?&?y)?!=?0);
二進制?|?運算符是為整型和?bool?類型預定義的。對于整型，|?對操作數進行按位“或”運算。對于?bool?操作數，|?對操作數進行邏輯“或”計算，也就是說，當且僅當兩個操作數均為?false?時，其結果才為?false。
b?=?x?|?y;
為整型和?bool?類型預定義了?^?二進制操作數。對于整型，^?計算操作數的按位“異或”。對于?bool?操作數，^?計算操作數的邏輯“異或”；也就是說，當且僅當只有一個操作數為?true?時，其結果才為?true。
b?=?x?^?y;
注：位邏輯運算符只作用于Integers類型

其它運算符
索引。定位在數組中i位置的值。
array[i]?=?3;
//將3負值到array數組第i位置上
使用?x1,x2,...,xn?這樣的方法將各種值傳送到function中進行運算。
示例:
double?SL=Ask-25*Point;
double?TP=Ask+25*Point;
int?ticket=OrderSend(Symbol(),OP_BUY,1,Ask,3,SL,TP,
"My?comment",123,0,Red);

操作符?[Operators]?
格式和嵌套
格式.一個操作符可以占用一行或者多行，兩個或多個操作符可以占用更多的行。
嵌套.執行控制符(if,?if-else,?switch,?while?and?for)可以進行任意嵌套.

復合操作符
一個復合操作符有一個(一個區段)和由一個或多個任何類型的操作符組成的的附件{}.?每個表達式使用分號作為結束(;)
示例:
if(x==0)
{
x=1;?y=2;?z=3;
}

表達式操作符
任何以分號(;)結束的表達式都被視為是一個操作符。
Assignment?operator.
Identifier=expression;
標識符=表達式;
示例:
x=3;
y=x=3;?//?這是錯誤的
一個操作符中只能有一個表達式。
調用函數操作符
Function_name(argument1,...,?argumentN);
函數名稱(參數1,...,參數N);
示例:
fclose(file);
空操作符
只有一個分號組成(;).我們用它來表示沒有任何表達式的空操作符.

停止操作符
一個break;?,?我們將其放在嵌套內的指定位置,用來在指定情況下跳出循環操作.
示例:
//?從0開始搜索數組
for(i=0;i<ARRAY_SIZE;I++)
if((array[i]==0)
break;

繼續操作符
一個continue;我們將其放在嵌套內的指定位置,用來在指定情況下跳過接下來的運算，直接跳入下一次的循環。
示例:
//?summary?of?nonzero?elements?of?array
int?func(int?array[])
{
int?array_size=ArraySize(array);
int?sum=0;
for(int?i=0;i
{
if(a[i]==0)?continue;
sum+=a[i];
}
return(sum);
}

返回操作符
一個return;將需要返回的結果放在return后面的()中。
示例:
return(x+y);

條件操作符?if
if?(expression)
operator;
如果表達式為真那么執行操作。
示例:
if(a==x)
temp*=3;
temp=MathAbs(temp);

條件操作符?if-else
if?(expression)
operator1
else
operator2
如果表達式為真那么執行operator1，如果為假執行operator2，else后還可以跟進多個if執行多項選擇。詳見示例。
示例:
if(x>1)
if(y==2)
z=5;
else
z=6;?
if(x>l)
{
if(y==2)?z=5;
}
else
{
z=6;
}
//?多項選擇
if(x=='a')
{
y=1;
}
else?if(x=='b')
{
y=2;
z=3;
}
else?if(x=='c')
{
y?=?4;
}
else
{
Print("ERROR");
}

選擇操作符?switch
switch?(expression)
{
case?constant1:?operators;?break;
case?constant2:?operators;?break;
...
default:?operators;?break;
}
當表達式expression的值等于結果之一時，執行其結果下的操作。不管結果如何都將執行default中的操作。
示例:
case?3+4:?//正確的
case?X+Y:?//錯誤的
被選擇的結果只可以是常數，不可為變量或表達式。
示例:
switch(x)
{
case?'A':
Print("CASE?A\n");
break;
case?'B':
case?'C':
Print("CASE?B?or?C\n");
break;
default:
Print("NOT?A,?B?or?C\n");
break;
}

循環操作符?while
while?(expression)
operator;
只要表達式expression為真就執行操作operator
示例:
while(k<N)
{
y=y*x;
k++;
}

循環操作符?for
for?(expression1;?expression2;?expression3)
operator;
用表達式1(expression1)來定義初始變量,當表達式2(expression2)為真的時候執行操作operator,在每次循環結束后執行表達式3(expression3)
用while可以表示為這樣:
expression1;
while?(expression2)
{
operator;
expression3;
};
示例:
for(x=1;x<=7;x++)
Print(MathPower(x,2));
使用for(;;)可以造成一個死循環如同while(true)一樣.
表達式1和表達式3都可以內嵌多個用逗號(,)分割的表達式。
示例:
for(i=0,j=n-l;i<N;I++,J--)
a[i]=a[j];
函數?[Function]
函數定義
一個函數是由返回值、輸入參數、內嵌操作所組成的。
示例:
double?//?返回值類型
linfunc?(double?x,?double?a,?double?b)?//?函數名和輸入參數
{
//?內嵌的操作
return?(a*x?+?b);?//?返回值
}
如果沒有返回值那么返回值的類型可以寫為void
示例:
void?errmesg(string?s)
{
Print("error:?"+s);
}

函數調用
function_name?(x1,x2,...,xn)
示例:
int?somefunc()
{
double?a=linfunc(0.3,?10.5,?8);
}
double?linfunc(double?x,?double?a,?double?b)
{
return?(a*x?+?b);
}

特殊函數?init()、deinit()和start()
init()在載入時調用，可以用此函數在開始自定義指標或者自動交易之前做初始化操作。
deinit()在卸載時調用，可以用此函數在去處自定義指標或者自動交易之前做初始化操作。
start()當數據變動時觸發，對于自定義指標或者自動交易的編程主要依靠此函數進行。
變量?[Variables]

內部變量顧名思義是在內部使用的，可以理解為在當前嵌套內所使用的變量。

函數參數定義
示例:
void?func(int?x,?double?y,?bool?z)
{
...
}
函數的參數內的變量只能在函數內才生效，在函數外無法使用，而且在函數內對變量進行的修改在函數外無法生效。
調用函數示例:
func(123,?0.5);
如果有需要在變量傳入由參數傳入函數內操作后保留修改在函數外生效的情況的話，可以在參數定義的類型名稱后加上修飾符(&)。
示例:
void?func(int&?x,?double&?y,?double&?z[])
{
...
}

靜態變量定義
在數據類型前加上static就可以將變量定義成靜態變量
示例:
{
static?int?flag
}

全局變量定義
全局變量是指在整個程序中都能夠調用的變量，只需將變量定義卸載所有嵌套之外即可。
示例:
int?Global_flag;
int?start()
{
...
}

附加變量定義
附加變量可以允許由用戶自己輸入。
示例:
extern?double?InputParameter1?=?1.0;
int?init()
{
...
}

初始化變量
變量必須經過初始化才可以使用。

基本類型
示例:
int?mt?=?1;?//?integer?初始化
//?double?初始化
double?p?=?MarketInfo(Symbol(),MODE_POINT);
//?string?初始化
string?s?=?"hello";
