如何在 pinescript 的安全功能（多 TF 指标）中使用输入？

Question

我试图修改 Tradingview 上已经可用的指标。

想法是将 WaveTrends 转换为 "line" 指标，当满足超卖或超买条件时会改变颜色。这些指标是另一个时间范围内的波浪趋势。

我有两个问题，我想使用一个输入函数来更改时间范围，而不必通过更改代码来完成。

第二期，图片上可以看到4行

中期 TF 短路情况
longTF空头条件
中期 TF 多头条件
longTF 长条件。

我通过创建 2 条长线和 2 条短线来绕过我的困难，但我想将它们组合成 3 种不同颜色的 2 条线：绿色表示超卖状态，红色表示超买状态，最后是灰色.

n1 = input(10, "Channel Length")
n2 = input(21, "Average Length")
obLevel1 = input(60, "Over Bought Level 1")
obLevel2 = input(53, "Over Bought Level 2")
osLevel1 = input(-60, "Over Sold Level 1")
osLevel2 = input(-53, "Over Sold Level 2")

ap = hlc3 
esa = ema(ap, n1)
d = ema(abs(ap - esa), n1)
ci = (ap - esa) / (0.015 * d)
tci = ema(ci, n2)

wt1 = tci
wt2 = sma(wt1,4)

//Mid and longer TF defining

long = input("D", "Interval used for long TF", type = resolution)
mid = input("360", "Interval used for mid TF", type = resolution)

**MidWT = security(tickerid, "360",wt2)
LongWT = security(tickerid, "720", wt2)**

//treshold MT LT

LWTLT = input(-53, "OS Threshold L")
LWTMT = input(-53, "OS Threshold M")
SWTLT = input(53, "OB Threshold L")
SWTMT = input(53, "OB Threshold M")

L1=1
M1=2
L2=3
M2=4

// Color for MT LT indicators

**lcolor1 = LongWT <= LWTLT ? lime : gray
mcolor1 = MidWT <= LWTMT ? lime : gray
lcolor2 = LongWT >= SWTLT ? red : gray
mcolor2 = MidWT >= SWTMT ? red : gray**

// plot

plot(L1, style=line,color=lcolor1,linewidth=25)
plot(M1, style=line,color=mcolor1,linewidth=25)
plot(L2, style=line,color=lcolor2,linewidth=25)
plot(M2, style=line,color=mcolor2,linewidth=25)

启用您输入的请求以供解决。默认值应该是出现在下拉列表中的值，因此将 "360" 更改为 "240"。

对于颜色，一行的条件现在集中在一个语句中。请注意如何将多个三元条件嵌入彼此。当你不习惯它们时，它们更难遵循，但非常方便。

记得在发布代码时在脚本的开头包含编译器指令，这样我们就可以知道您的脚本是为哪个版本的 Pine 编写的。
