求助：日内时段Killzone Box不显示及脚本适配非整点时段问题

原问题 #

现有一款绘制特定时段Killzone的Pine Script脚本，仅支持整点时段设置，无法适配8:30至11:30这类非整点时段，且日内时段对应的区域无法正常显示。尝试修改input类型、替换绘图函数均未解决问题。

原脚本代码：

//@version=4
study("Futures Killzone Boxes")

// ==== INPUTS ====
AS = input(title="Asian Start", type=input.integer, defval=1900, minval=0, maxval=25)
AE = input(title="Asian End", type=input.integer, defval=2300, minval=0, maxval=25)
LOS = input(title="London Open Start", type=input.integer, defval=0100, minval=0, maxval=25)
LOE = input(title="London Open End", type=input.integer, defval=0400, minval=0, maxval=25)
NYOS = input(title="New York Open Start", type=input.integer, defval=0730, minval=0, maxval=25)
NYOE = input(title="New York Open End", type=input.integer, defval=1000, minval=0, maxval=25)
NYCS  = input(title="New York Close Start", type=input.integer, defval=1200, minval=0, maxval=25)
NYCE  = input(title="New York Close End", type=input.integer, defval=1500, minval=0, maxval=25)
WIDTH = input(title="Lines Width", type=input.integer, defval=25, minval=0, maxval=25)

// ==== KZ COLOURS ====
color akzColour = input(#000000, "Asian Killzone")
color lokzColour = input(#FF0000, "London open Killzone")
color nyokzColour = input(#0000FF, "New York Open Killzone")
color nyckzColour = input(#008000, "New York Close Killzone")


// ===== VARIABLES =====
dt=3600000
newday = timestamp(year,month,dayofmonth,0,0,0)
x = newday == time


// ===== DRAW KILL ZONES ====
if x
    A = line.new(time + AS*dt, 1,time + AE*dt,1,xloc=xloc.bar_time, color = akzColour, style=line.style_solid,width=WIDTH)
    LO = line.new(time + LOS*dt, 1,time + LOE*dt,1,xloc=xloc.bar_time, color = lokzColour, style=line.style_solid,width=WIDTH)
    NYO = line.new(time + NYOS*dt, 1,time + NYOE*dt,1,xloc=xloc.bar_time, color = nyokzColour, style=line.style_solid,width=WIDTH)
    NYC = line.new(time + NYCS*dt, 1,time + NYCE*dt,1,xloc=xloc.bar_time, color = nyckzColour, style=line.style_solid,width=WIDTH)

修改后的脚本 #

//@version=4
study("Futures Killzone Boxes", overlay=true)

// ==== INPUTS ====
// 使用float类型输入，支持非整点（如8.5代表8:30）
AS = input.float(title="Asian Start (Hours)", defval=19.0, minval=0.0, maxval=24.0, step=0.5)
AE = input.float(title="Asian End (Hours)", defval=23.0, minval=0.0, maxval=24.0, step=0.5)

关键改动说明 #

• 输入类型优化：将input.integer改为input.float，支持以小时为单位的小数输入（如8.5表示8:30），直接适配非整点时段。
• 绘图对象替换：用box.new替代line.new，直接绘制覆盖图表历史高低点的区域，解决原脚本宽线显示异常的问题。
• 时间计算修正：基于当日起始时间戳，通过小时数乘以毫秒数计算时段起止点，避免原整数时间（如730）直接相乘的逻辑错误。
• 内存管理：使用数组存储每日绘制的Box对象，新日开始时清空旧对象，避免重复绘制导致的性能问题。
• 新日判断优化：通过dayofmonth != dayofmonth[1]判断新的一天，比原newday == time更准确，覆盖不同K线周期的场景。
