如何在Pine Script中按4种条件设置平仓止损？

开仓后需依据以下4种不同条件设置自动止损，但当前代码中strategy.exit的止损逻辑存在偏差，请求修正：

• 开仓后价格即刻跌破Vegas channel，且Volume Osc指标高于144参数线，立即以当前价格止损。
• 开仓后价格即刻跌破Vegas channel，且Volume Osc指标低于144，观察24小时内是否出现加速下跌（如跌幅5%），若无加速，止损设置在支撑位。
• 跌破后无明显加速，但24小时内无法回到Vegas channel顶部，也进行止损，最终止损位设置在Vegas channel下方。
• 价格未跌破Vegas channel时，常规设置6%的止损。

备注：Vegas channel=ema144与ema169之间的区间。

现有Pine Script代码如下：

strategy("Vegas", overlay=true, precision=2, pyramiding=6, initial_capital=6000)

//---Volume Oscillator---
var cumVol = 0.
cumVol += nz(volume)
if barstate.islast and cumVol == 0
    runtime.error("No volume is provided by the data vendor.")

longlen = input.int(14, minval=1, title = "Long Length")
short = ta.ema(volume, shortlen)
long = ta.ema(volume, longlen)
osc = 100 * (short - long) / long

//---Support and Resistance Levels---

s1 = plot(lowUsePivot, color=ta.change(lowUsePivot) ? na : #007bff,  linewidth=3, offset=-(rightBars+1), title="Support")

//---Settings---

ordersize=1000/close

vegas_long = (out144>out576 and out169>out576) and (out144>out676 and out169>out676)
vegas_short = (out144<out576 and out169<out576) and (out144<out676 and out169<out676)
vegas_max = math.max(out144,out169)
vegas_min = math.min(out144,out169)
distance_long = low-vegas_max
distance_short = vegas_min-high
vegas_long2 = out12>out144 and out12>out169
vegas_short2 = out12<out144 and out12<out169
opengap = input.int(title="Next Position Gap", defval=1)
dist_min = input.float(title="Min Distance", defval=1)
dist_max = input.float(title="Max Distance", defval=25)

//---Long---
longCondition = vegas_long and vegas_long2 and (low>vegas_max and distance_long>dist_min and distance_long<=dist_max)

if longCondition and (strategy.position_size == 0 or (strategy.position_size > 0 and close<strategy.position_avg_price and strategy.position_avg_price-close>=opengap))

longTP_pc  = strategy.position_avg_price*(1+pc)
longSL_pc  = strategy.position_avg_price*(1-pc)
longSL_support = lowUsePivot

if strategy.position_size > 0 and (barstate.isnew and ta.crossunder(strategy.position_avg_price,vegas_max) and osc > 144)
    strategy.exit("Close Long","Long", limit=longTP_pc, stop=close, alert_message = "Close Long")

if strategy.position_size > 0 and (barstate.isnew and ta.crossunder(strategy.position_avg_price,vegas_max) and osc < 144)
    strategy.exit("Close Long","Long", limit=longTP_pc, stop=longSL_support, alert_message = "Close Long")

if strategy.position_size > 0 and (barstate.isnew and osc < 144)
    strategy.exit("Close Long","Long", limit=longTP_pc, stop=longSL_pc, alert_message = "Close Long")
