⚠️ CRITICAL: Pine Script Syntax Rules

⚠️ 重要提示：Pine Script 语法规则

BEFORE writing ANY multi-line Pine Script code, remember:

TERNARY OPERATORS (
```
? :
```
) - MUST stay on ONE line or use intermediate variables
Line continuation - ALL continuation lines must be indented MORE than the starting line
Common error: "end of line without line continuation" - caused by improper line breaks

pinescript

// ❌ NEVER DO THIS:
text = condition ? "value1" :
       "value2"

// ✅ ALWAYS DO THIS:
text = condition ? "value1" : "value2"

See the "Line Wrapping Rules" section below for complete rules.

在编写任何多行Pine Script代码之前，请记住：

三元运算符 (
```
? :
```
) - 必须保持在同一行，或使用中间变量
换行续行 - 所有续行的缩进必须比起始行更深
常见错误："end of line without line continuation"（未使用续行符导致行结束）- 由不正确的换行引起

pinescript

// ❌ 绝对不要这样做：
text = condition ? "value1" :
       "value2"

// ✅ 请始终这样做：
text = condition ? "value1" : "value2"

请查看下方的“换行规则”部分获取完整规则。

Project File Management

项目文件管理

When starting a new project, work with the file that has been renamed from blank.pine
Always save work to
```
/projects/[project-name].pine
```
Never create new files unless specifically needed for multi-file projects
Update the file header with accurate project information

启动新项目时，使用从blank.pine重命名的文件
始终将工作保存到
```
/projects/[project-name].pine
```
除非多文件项目明确需要，否则不要创建新文件
使用准确的项目信息更新文件头

CRITICAL: Line Wrapping Rules

重要提示：换行规则

Pine Script has STRICT line continuation rules that MUST be followed:

Indentation Rule: Lines MUST be indented more than the first line
Break at operators/commas: Split AFTER operators or commas, not before
Function arguments: Each continuation must be indented
No explicit continuation character in Pine Script v6

Pine Script有严格的续行规则，必须遵守：

缩进规则：续行的缩进必须比第一行更深
在运算符/逗号后换行：在运算符或逗号后拆分，不要在前面
函数参数：每个续行必须缩进
Pine Script v6中没有显式续行符

CRITICAL: Ternary Operators MUST Stay on One Line

重要提示：三元运算符必须保持在同一行

pinescript

// WRONG - Will cause "end of line without line continuation" error
text = condition ?
    "true value" :
    "false value"

// CORRECT - Entire ternary on one line
text = condition ? "true value" : "false value"

// CORRECT - For long ternaries, assign intermediate variables
trueText = str.format("Long true value with {0}", param)
falseText = str.format("Long false value with {0}", other)
text = condition ? trueText : falseText

pinescript

// 错误 - 会导致"end of line without line continuation"错误
text = condition ?
    "true value" :
    "false value"

// 正确 - 整个三元运算符在一行
text = condition ? "true value" : "false value"

// 正确 - 对于长三元运算符，使用中间变量
trueText = str.format("Long true value with {0}", param)
falseText = str.format("Long false value with {0}", other)
text = condition ? trueText : falseText

CORRECT Line Wrapping:

正确的换行方式：

pinescript

// CORRECT - indented continuation
longCondition = ta.crossover(ema50, ema200) and
     rsi < 30 and
     volume > ta.sma(volume, 20)

// CORRECT - function arguments
plot(series,
     title="My Plot",
     color=color.blue,
     linewidth=2)

// CORRECT - long calculations
result = (high - low) / 2 +
     (close - open) * 1.5 +
     volume / 1000000

pinescript

// 正确 - 缩进的续行
longCondition = ta.crossover(ema50, ema200) and
     rsi < 30 and
     volume > ta.sma(volume, 20)

// 正确 - 函数参数
plot(series,
     title="My Plot",
     color=color.blue,
     linewidth=2)

// 正确 - 长计算
result = (high - low) / 2 +
     (close - open) * 1.5 +
     volume / 1000000

INCORRECT Line Wrapping (WILL CAUSE ERRORS):

错误的换行方式（会导致错误）：

pinescript

// WRONG - same indentation
longCondition = ta.crossover(ema50, ema200) and
rsi < 30 and
volume > ta.sma(volume, 20)

// WRONG - not indented enough
plot(series,
title="My Plot",
color=color.blue)

pinescript

// 错误 - 相同缩进
longCondition = ta.crossover(ema50, ema200) and
rsi < 30 and
volume > ta.sma(volume, 20)

// 错误 - 缩进不足
plot(series,
title="My Plot",
color=color.blue)

CRITICAL: Plot Scope Restriction

重要提示：绘图作用域限制

NEVER use plot() inside local scopes - This causes "Cannot use 'plot' in local scope" error

pinescript

// ❌ WRONG - These will ALL fail:
if condition
    plot(value)  // ERROR!

for i = 0 to 10
    plot(close[i])  // ERROR!

myFunc() =>
    plot(close)  // ERROR!

// ✅ CORRECT - Use these patterns instead:
plot(condition ? value : na)  // Conditional plotting
plot(value, color=condition ? color.blue : color.new(color.blue, 100))  // Conditional styling

// For dynamic drawing in local scopes, use:
if condition
    line.new(...)  // OK
    label.new(...)  // OK
    box.new(...)   // OK

绝对不要在局部作用域内使用plot() - 这会导致"Cannot use 'plot' in local scope"错误

pinescript

// ❌ 错误 - 这些都会失败：
if condition
    plot(value)  // 错误！

for i = 0 to 10
    plot(close[i])  // 错误！

myFunc() =>
    plot(close)  // 错误！

// ✅ 正确 - 请改用以下模式：
plot(condition ? value : na)  // 条件绘图
plot(value, color=condition ? color.blue : color.new(color.blue, 100))  // 条件样式

// 如需在局部作用域内动态绘图，请使用：
if condition
    line.new(...)  // 允许
    label.new(...)  // 允许
    box.new(...)   // 允许

Best Practices

最佳实践

Avoid Repainting

避免重绘

Use barstate.isconfirmed for signals
Proper request.security() with lookahead=barmerge.lookahead_off
Document any intentional repainting

对信号使用barstate.isconfirmed
正确使用request.security()并设置lookahead=barmerge.lookahead_off
记录任何有意的重绘行为

Performance Optimization

性能优化

Minimize security() calls
Cache repeated calculations
Use switch instead of multiple ifs
Optimize array operations

减少security()调用次数
缓存重复计算
使用switch替代多个if语句
优化数组操作

User Experience

用户体验

Logical input grouping with group= parameter
Helpful tooltips for complex inputs
Sensible default values
Clear input labels

使用group=参数按逻辑分组输入
为复杂输入添加有用的工具提示
合理的默认值
清晰的输入标签

Error Handling

错误处理

Check for na values before operations
Handle edge cases (first bars, division by zero)
Graceful degradation when data unavailable

在操作前检查na值
处理边缘情况（首根K线、除零错误）
数据不可用时优雅降级

TradingView Constraints

Code Review Checklist

代码审查清单

Example: Moving Average Cross Strategy

示例：均线交叉策略

pinescript

//@version=6
strategy("MA Cross Strategy", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=10)

// Inputs
fastLength = input.int(50, "Fast MA Length", minval=1, group="Moving Averages")
slowLength = input.int(200, "Slow MA Length", minval=1, group="Moving Averages")
maType = input.string("EMA", "MA Type", options=["SMA", "EMA", "WMA"], group="Moving Averages")

// Calculations
ma(source, length, type) =>
    switch type
        "SMA" => ta.sma(source, length)
        "EMA" => ta.ema(source, length)
        "WMA" => ta.wma(source, length)

fastMA = ma(close, fastLength, maType)
slowMA = ma(close, slowLength, maType)

// Conditions
longCondition = ta.crossover(fastMA, slowMA)
shortCondition = ta.crossunder(fastMA, slowMA)

// Strategy
if longCondition
    strategy.entry("Long", strategy.long)
if shortCondition
    strategy.close("Long")

// Plots
plot(fastMA, "Fast MA", color.blue, 2)
plot(slowMA, "Slow MA", color.red, 2)

Write code that is production-ready, efficient, and follows all Pine Script v6 best practices.
