有人能帮我解决我用 pinescript 写的交易策略吗？

Question

我正在使用以下代码

**

//@version=2
// Define variables
fastPeriod = 12
slowPeriod = 26

// Calculate the fast and slow moving averages
fastMa = sma(close, fastPeriod)
slowMa = sma(close, slowPeriod)

// Enter a long position when the fast MA crosses above the slow MA
if (fastMa > slowMa)
  strategy.entry("Long", strategy.long)
  plot(bar_index, high, "Buy", "arrowup", color=green, offset=-5)

// Enter a short position when the fast MA crosses below the slow MA
if (fastMa < slowMa)
  strategy.entry("Short", strategy.short)
  plot(bar_index, low, "Sell", "arrowdown", color=red, offset=-5)

// Close the position when the opposite condition is met
if (fastMa < slowMa)
  strategy.close("Long")
  plot(bar_index, low, "Sell", "arrowdown", color=red, offset=-5)
if (fastMa > slowMa)
  strategy.close("Short")
  plot(bar_index, high, "Buy", "arrowup", color=green, offset=-5)

**

并面临以下错误消息编译错误。 第 11 行：不匹配的输入“strategy.entry”期望“没有行继续的行结束”

我希望能够编译脚本并在我的图表上看到它。 谢谢！

//@version=2
// Define variables
fastPeriod = 12
slowPeriod = 26

// Calculate the fast and slow moving averages
fastMa = sma(close, fastPeriod)
slowMa = sma(close, slowPeriod)

// Enter a long position when the fast MA crosses above the slow MA
if (fastMa > slowMa)
    strategy.entry("Long", strategy.long)
    plot(bar_index, high, "Buy", "arrowup", color=green, offset=-5)

// Enter a short position when the fast MA crosses below the slow MA
if (fastMa < slowMa)
    strategy.entry("Short", strategy.short)
    plot(bar_index, low, "Sell", "arrowdown", color=red, offset=-5)

// Close the position when the opposite condition is met
if (fastMa < slowMa)
    strategy.close("Long")
    plot(bar_index, low, "Sell", "arrowdown", color=red, offset=-5)
if (fastMa > slowMa)
    strategy.close("Short")
    plot(bar_index, high, "Buy", "arrowup", color=green, offset=-5)

strategy.entry 和 plot 行之前的间距已关闭。 我删除并添加了 4 个空格键

它修复了以下与 bar_index 相关的新错误

Compilation error. Line 13: Undeclared identifier 'bar_index';
