Prior Close Percent Grid (Session-Aware)
TradingView's price scale shows prices only, and the built-in Percent scale measures change from the first visible bar, so its zero point moves every time you scroll or zoom. This indicator draws a percent grid anchored to the prior close, so you can read at a glance how far price is from the previous close, including during pre-market, post-market and overnight sessions.
How the baseline (0%) is chosen
The script treats the overnight session as the start of the next trading day:
• Pre-market and regular hours: previous regular-session close
• Post-market: still the previous regular-session close, so the after-hours move is read against the same baseline as the day session
• Overnight session: today's regular-session close
The baseline is the official close from regular-session daily data, not the close of the last intraday bar.
What it draws
• A gray step line at the baseline (0%) of each session
• Dotted grid lines every N% above and below the baseline, labeled with the percent value (green above, red below)
• Past sessions: the grid only covers the range that session actually traded, so the chart is not squashed
• Current session: the grid covers at least ±N% (default 30%) and extends to the right
• Hover over any bar: the status line and Data Window show that bar's close as % change vs its own baseline
• An info box shows the current baseline, the date of the close it comes from, and the current % change
How to use
• Designed for intraday charts. On daily and higher timeframes the baseline is simply the previous bar's close.
• To see overnight bars on BOATS-supported US stocks, switch the chart session to 24h. With Regular or Extended sessions the script works the same way, just without overnight bars.
• Markets without extended sessions always use the previous close.
• If the chart looks compressed, right-click the price scale and enable "Scale price chart only".
Settings
• Grid step (%): spacing between grid lines
• Current session: draw at least ± (%): minimum grid range for the live session; 0 = traded range only
• Overnight session starts at: exchange time zone, default 20:00 for US stocks
• Draw grid on past sessions, colors, label size
Limitations
• The overnight start time comes from the input, not from the exchange, so adjust it if your market differs.

概述
TradingView 的价格轴只显示价格；自带的百分比坐标以屏幕最左边那根 K 线为 0%，一拖动或缩放零点就变。本指标以昨收为 0% 画出百分比刻度，盘前、盘后、夜盘都能直接看出价格相对昨收涨跌了多少。
基准（0%）的规则
脚本把夜盘视为下一个交易日的开始：
• 盘前、盘中：前一交易日常规时段收盘价
• 盘后：仍是前一交易日收盘价，盘后涨跌和日盘用同一个基准
• 夜盘：当天常规时段收盘价
基准取自常规时段日线的官方收盘价，不是最后一根分钟 K 线的收盘价。
显示内容
• 灰色阶梯线：每个时段的 0% 基准
• 每隔 N% 一条虚线并标注百分比，上涨绿色、下跌红色
• 历史时段：刻度只覆盖该时段实际走过的价格范围，不会把 K 线压扁
• 当前时段：刻度至少覆盖 ±N%（默认 30%），并向右延伸
• 鼠标悬停任意 K 线：状态栏和数据窗口显示该 K 线收盘价相对其基准的涨跌幅
• 右上角信息框：当前基准价、基准对应的收盘日期、当前涨跌幅
使用方法
• 用于日内周期。日线及以上周期，基准就是前一根 K 线的收盘价。
• 支持 BOATS 的美股要看夜盘，需把图表时段切到 24h。常规或延长时段下用法相同，只是没有夜盘 K 线。
• 没有延长交易时段的市场，始终以昨收为基准。
• 如果 K 线被压扁，右键价格轴，勾选"仅缩放价格图表"。
参数
• Grid step (%)：刻度间隔
• Current session: draw at least ± (%)：当前时段至少画到的范围；0 = 只画实际走过的范围
• Overnight session starts at：夜盘开始时间（交易所时区），美股默认 20:00
• Draw grid on past sessions：历史时段是否画刻度；另有颜色和文字大小
局限
• 夜盘开始时间来自参数设置，不是从交易所自动识别的，其他市场需要自行调整。
