问题

我正在尝试通过迭代方式查找高点，而不使用内置的pivothigh/highest，因为它们是通过指定要查找的一定范围的 bars 来工作的。相反，我正在定义起始 bar，从这个 bar 开始搜索前一个 bar 较低且下一个 bar 也较低的 bar。它应该将此 bar 检测为"Higher High"。然后，我将查看所有找到的高点之间的点差变化，并剔除那些超出某个阈值的不需要的 bars。

目前，我得到的是最高点之后的 bars（用蓝色十字标记），但我需要标有红色点的 bars。如何修复这个问题？

//@version=5
indicator("My script", overlay=true)

lineDate = input.time(timestamp("22 Feb 2023 18:00"), title="Line Location")

if barstate.islastconfirmedhistory
    line.new(x1=lineDate, y1=high, x2=lineDate, y2=low, extend=extend.both, 
         color=color.orange, width=2, xloc=xloc.bar_time)

startbar = time == lineDate
start_bar = ta.change(startbar)
bars_since_new_index = ta.barssince(start_bar)

int hh = na

// 从起始 bar 迭代到最新 bar
for i = bars_since_new_index to 0 
    // 检查是否为较高点
    next_high = high[i]
    current_high = high[i+1]
    previous_high = high[i+2]
    if current_high > previous_high and next_high < current_high
        hh := i+1
    else
        hh := na

plotshape(hh)

I am trying to find Highs iteratively, without using built in pivothigh/highest, because they are working by specifying a range of bars to look for. Instead, I am defining the starting bar, from which I search for bar that has previous bar lower, and next bar lower. It should detect this bar as Higher High. Then I will see the pips change between all found highs, and cull unwanted bars if they are outside some threshold.

currently I am getting bars after the highest (marked in blue crosses), but I need the ones marked with red dots.

How can I fix that?

//@version=5
indicator("My script", overlay=true)

lineDate = input.time(timestamp("22 Feb 2023 18:00"), title="Line Location")

if barstate.islastconfirmedhistory
line.new(x1=lineDate, y1=high, x2=lineDate, y2=low, extend=extend.both,
color=color.orange, width=2, xloc=xloc.bar_time)

startbar = time == lineDate
start_bar = ta.change(startbar)
bars_since_new_index = ta.barssince(start_bar)

int hh = na

// Iterate from start bar to the newest bar
for i = bars_since_new_index to 0
// Check for higher high
next_high = high[i]
current_high = high[i+1]
previous_high = high[i+2]
if current_high > previous_high and next_high < current_high
hh := i+1
else
hh := na

plotshape(hh)

I think the problem is in your loop which execute on each bar and then give you the false impression of working.

I propose you to execute the loop only once all the bar are drawn and I used label.new instead of plotshape because you can use label in loop.

Here is the corrected code:

```pinescript
//@version=5
indicator("My script", overlay=true)

lineDate = input.time(timestamp("14 Mar 2023 18:00"), title="Line Location")

if barstate.islastconfirmedhistory
    line.new(x1=lineDate, y1=high, x2=lineDate, y2=low, extend=extend.both, 
         color=color.orange, width=2, xloc=xloc.bar_time)

startbar = time == lineDate
start_bar = ta.change(startbar)
bars_since_new_index = ta.barssince(start_bar)

int hh = na

if barstate.islastconfirmedhistory
    // Iterate from start bar to the newest bar
    for i = bars_since_new_index to 0 
        // Check for higher high
        next_high = high[i]
        current_high = high[i+1]
        previous_high = high[i+2]
        if current_high > previous_high and next_high < current_high
            label.new(bar_index - i - 1, close, "x", yloc=yloc.abovebar, style=label.style_none)

//@version=5
indicator("My script", overlay=true)

lineDate = input.time(timestamp("14 Mar 2023 18:00"), title="Line Location")

if barstate.islastconfirmedhistory
    line.new(x1=lineDate, y1=high, x2=lineDate, y2=low, extend=extend.both, 
         color=color.orange, width=2, xloc=xloc.bar_time)


startbar = time == lineDate
start_bar = ta.change(startbar)
bars_since_new_index = ta.barssince(start_bar)

int hh = na

if barstate.islastconfirmedhistory
    // Iterate from start bar to the newest bar
    for i = bars_since_new_index to 0 
        // Check for higher high
        next_high = high[i]
        current_high = high[i+1]
        previous_high = high[i+2]
        if current_high > previous_high and next_high < current_high
            label.new(bar_index - i - 1, close, "x", yloc=yloc.abovebar, style=label.style_none)
