TradingView Pine Script修改：手动绘制SpotGamma五类水平价格线

以下是满足你需求的优化版脚本，实现了可修改线型、线条无限延伸、无冒号标签的功能：

//@version=5
indicator("SpotGamma 水平价格线", shorttitle="SpotGamma Levels", overlay=true)

// --- KEY GAMMA 设置 ---
key_gamma_price = input.float(1, title="KEY GAMMA", tooltip="手动输入KEY GAMMA价格水平")
key_gamma_color = input.color(#007bff, title="KEY GAMMA 颜色")
key_gamma_linewidth = input.int(2, title="KEY GAMMA 线宽", minval=1, maxval=5)
key_gamma_style = input.string("solid", title="KEY GAMMA 线型", options=["solid", "dashed", "dotted", "dashed_dotted"])

// --- KEY DELTA 设置 ---
key_delta_price = input.float(1, title="KEY DELTA", tooltip="手动输入KEY DELTA价格水平")
key_delta_color = input.color(#f2ff00, title="KEY DELTA 颜色")
key_delta_linewidth = input.int(2, title="KEY DELTA 线宽", minval=1, maxval=5)
key_delta_style = input.string("solid", title="KEY DELTA 线型", options=["solid", "dashed", "dotted", "dashed_dotted"])

// --- HEDGE WALL 设置 ---
hedge_wall_price = input.float(1, title="HEDGE WALL", tooltip="手动输入HEDGE WALL价格水平")
hedge_wall_color = input.color(#ff00a2, title="HEDGE WALL 颜色")
hedge_wall_linewidth = input.int(2, title="HEDGE WALL 线宽", minval=1, maxval=5)
hedge_wall_style = input.string("solid", title="HEDGE WALL 线型", options=["solid", "dashed", "dotted", "dashed_dotted"])

// --- CALL WALL 设置 ---

// --- PUT WALL 设置 ---

put_wall_style = input.string("solid", title="PUT WALL 线型", options=["solid", "dashed", "dotted", "dashed_dotted"])

// --- 绘制水平线（无限延伸）---

hline(put_wall_price, title="PUT WALL", color=put_wall_color, linewidth=put_wall_linewidth, style=put_wall_style)

// --- 绘制无冒号标签（可选，可通过注释此段关闭）---
var label kg_label = label.new(bar_index, key_gamma_price, "KEY GAMMA " + str.tostring(key_gamma_price, "#.##"), color=key_gamma_color, textcolor=color.white, style=label.style_label_left, tooltip="KEY GAMMA 价格水平")

var label cw_label = label.new(bar_index, call_wall_price, "CALL WALL " + str.tostring(call_wall_price, "#.##"), color=call_wall_color, textcolor=color.black, style=label.style_label_left, tooltip="CALL WALL 价格水平")
var label pw_label = label.new(bar_index, put_wall_price, "PUT WALL " + str.tostring(put_wall_price, "#.##"), color=put_wall_color, textcolor=color.white, style=label.style_label_left, tooltip="PUT WALL 价格水平")

// 更新标签位置到最新K线
label.set_xy(kg_label, bar_index, key_gamma_price)
label.set_xy(kd_label, bar_index, key_delta_price)
label.set_xy(hw_label, bar_index, hedge_wall_price)
label.set_xy(cw_label, bar_index, call_wall_price)
label.set_xy(pw_label, bar_index, put_wall_price)

// 更新标签文本（价格变化时同步更新）
label.set_text(kg_label, "KEY GAMMA " + str.tostring(key_gamma_price, "#.##"))
label.set_text(kd_label, "KEY DELTA " + str.tostring(key_delta_price, "#.##"))
label.set_text(hw_label, "HEDGE WALL " + str.tostring(hedge_wall_price, "#.##"))
label.set_text(cw_label, "CALL WALL " + str.tostring(call_wall_price, "#.##"))
label.set_text(pw_label, "PUT WALL " + str.tostring(put_wall_price, "#.##"))

优化点说明 #

1. 线条无限延伸：使用Pine Script v5的hline()函数替代原脚本的plot()，该函数绘制的水平线默认贯穿整个图表区域，完全满足无限延伸需求。
2. 可自定义线型：为每个价格线添加了线型选择输入，支持solid（实线）、dashed（虚线）、dotted（点线）、dashed_dotted（点虚线）四种样式，可在设置面板调整。
3. 移除标签冒号：自定义标签文本格式，将原格式中的冒号（如KEY GAMMA: 123）改为空格分隔（KEY GAMMA 123），符合你的需求。如果不需要标签，直接注释掉标签相关代码即可。
4. 额外优化：增加了颜色、线宽的自定义选项，让脚本更灵活；标签会自动跟随最新K线移动，价格修改时同步更新文本。
