大家好，对交易视图和松树有点陌生，我找到了我想使用的策略，并希望将其转换为能够发送信号。尝试按照在线指南转换为学习，但出现错误，希望有人能提供帮助，谢谢。代码如下。

//@version=2
strategy("GetTrendStrategy", overlay=true)
tim=input('160')
out1 = security(tickerid, tim, open)
out2 = security(tickerid, tim, close)
plot(out1,color=red)
plot(out2,color=green)
longCondition = crossover(security(tickerid, tim, close),security(tickerid, tim, open))
if (longCondition)
    strategy.entry("long", strategy.long)
shortCondition = crossunder(security(tickerid, tim, close),security(tickerid, tim, open))
if (shortCondition)
    strategy.entry("short", strategy.short)
 

 This is my conversion. 

```//@Version.1 Signaler
study("GetTrendStrategy", overlay=true)
tim=input('160')
out1 = security(tickerid, tim, open)
out2 = security(tickerid, tim, close)
plot(out1,color=red)
plot(out2,color=green)
buy = crossover(security(tickerid, tim, close),security(tickerid, tim, open))
alertcondition("buy", title="Buy Signal",message="Buy Sigbal Alertstrategy)
sell = crossunder(security(tickerid, tim, close),security(tickerid, tim, open))
alertcondition("buy", title="Buy Signal",message="Buy Sigbal Alertstrategy)
plot(close)

这个脚本可以工作。
请注意，您只需将 resolution 输入的默认值设置为下拉菜单中的值。
详情请见Setting the default value of a resolution input in TradingView。

//@version=4
study("GetTrendStrategy", overlay=true)

tim = input("180", type=input.resolution)

[out1, out2] = security(syminfo.tickerid, tim, [open,close])

buy  = crossover(out2,out1)
sell = crossunder(out2,out1)

alertcondition(buy,  title="Buy Signal",  message="Buy Signal Alertstrategy")
alertcondition(sell, title="Sell Signal", message="Sell Signal Alertstrategy")

plot(out1, color=color.red)
plot(out2, color=color.green)
