如何获得2点之间的最大值？

我想获得2个条目之间的最高点（例如2个ema十字之间，如图像示例）。它在我头上，我barssince()没有运气就尝试过。任何帮助都将受到欢迎！

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

ema1 = ema(close, 20)
ema2 = ema(close, 50)
plot(ema1)
plot(ema2, color = color.yellow)

buy = crossover(ema1, ema2)
sell = crossunder(ema1, ema2)

highest_buy = highestbars(high, barssince(buy))

plot(highest_buy)

连续剧情：

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

var bool    track       = false
var float   highest_buy = na

ema1 = ema(close, 20)
ema2 = ema(close, 50)

buy  = crossover(ema1, ema2)
sell = crossunder(ema1, ema2)

if buy
    track := true
else if sell
    track := false

highest_buy := track ? max(nz(highest_buy), high) : na

plot(ema1)
plot(ema2,        color=color.yellow)
plot(highest_buy, color=color.purple, style=plot.style_linebr)

仅绘制最新出现的图：

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

var bool    track       = false
var float   highest_buy = na
var int     bar_buy     = na
var int     bar_sell    = na
var line    hline       = line.new(na, na, na, na, extend=extend.both, color=color.purple)

ema1 = ema(close, 20)
ema2 = ema(close, 50)

buy  = crossover(ema1, ema2)
sell = crossunder(ema1, ema2)

if buy
    track := true
    bar_buy := bar_index

highest_buy := track ? max(nz(highest_buy), high) : na

if sell
    track := false
    bar_sell := bar_index
    line.set_xy1(hline, bar_buy,  highest_buy)
    line.set_xy2(hline, bar_sell, highest_buy)


plot(ema1)
plot(ema2,        color=color.yellow)

bgcolor(buy  ? color.green : na, transp=80)
bgcolor(sell ? color.red   : na, transp=80)
