Pine脚本版本变更及停止重印重画问题

Question

这是一个非常小的松树脚本，遵循趋势，但我面临着重新绘制和重新打印的问题。

//@version=2

strategy("PrabhuTrendStrategy", 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)

Answer 1

在

//@version=2

中，

lookahead

参数设置为

barmerge.lookahead_on

，这将导致重新绘制。

将您的代码升级到

v5

并使用以下函数来实现共享的非重画安全功能这里。

// Function to securely and simply call `security()` so that it never repaints and never looks ahead.
f_secureSecurity(_symbol, _res, _src) => request.security(_symbol, _res, _src[1], lookahead = barmerge.lookahead_on)
