请求为Pine Script策略添加3%止盈1%止损平仓逻辑

你需要为现有均线交叉策略添加上涨3%止盈、下跌1%止损的平仓规则，以下是修改后的完整代码，并附上关键逻辑说明：

//@version=5

startDate = input(title="开始日期", defval=15)
startMonth = input(title="开始月份", defval=1)
startYear = input(title="开始年份", defval=2023)
afterStartDate = (time >= timestamp(syminfo.timezone, startYear, startMonth, startDate, 0, 0))
investment = input.int(defval=1000, title='投资金额 USDT')
comm = 0.08

// 新增可调整的止盈止损参数
takeProfitPerc = input.float(defval=3.0, title='止盈百分比 (%)', tooltip='持仓后达到该比例平仓')
stopLossPerc = input.float(defval=1.0, title='止损百分比 (%)', tooltip='持仓后达到该比例平仓')

strategy('BS WAB with lines', shorttitle='WAB', overlay=true, default_qty_value = 1000, commission_type = strategy.commission.percent, commission_value = comm)

// 定义价格与时间框架
src = input(close, title='数据源')
resolution = timeframe.period
price = request.security(syminfo.tickerid, resolution, src)

// 定义均线周期与类型
ma1Period = input.int(defval=8, title='周期', inline='1', group='移动平均线: 区域1')
ma1Type = input.string(defval='EMA', title='类型', options=['EMA', 'SMA', 'WMA', 'HMA', 'LIN'], tooltip='均线平滑方式', inline='1', group='移动平均线: 区域1')

ma2Period = input.int(defval=21, title='周期', inline='2', group='移动平均线: 区域1')
ma2Type = input.string(defval='EMA', title='类型', options=['EMA', 'SMA', 'WMA', 'HMA', 'LIN'], tooltip='均线平滑方式', inline='2', group='移动平均线: 区域1')

// 计算均线
ma1 = ma1Type == 'EMA' ? ta.ema(price, ma1Period) : ma1Type == 'SMA' ? ta.sma(price, ma1Period) : ma1Type == 'WMA' ? ta.wma(price, ma1Period) : ma1Type == 'HMA' ? ta.hma(price, ma1Period) : ma1Type == 'LIN' ? ta.linreg(price, ma1Period, 0) : na
ma2 = ma2Type == 'EMA' ? ta.ema(price, ma2Period) : ma2Type == 'SMA' ? ta.sma(price, ma2Period) : ma2Type == 'WMA' ? ta.wma(price, ma2Period) : ma2Type == 'HMA' ? ta.hma(price, ma2Period) : ma2Type == 'LIN' ? ta.linreg(price, ma2Period, 0) : na

// 定义趋势状态
TrendUp1() =>
    ma1 > ma2
TrendDown1() =>
    ma1 < ma2

trendColor1 = TrendUp1() ? color.green : TrendDown1() ? color.red : color.blue

// 绘制均线与填充
p_ma1 = plot(ma1)
p_ma2 = plot(ma2)
fill(p_ma1, p_ma2, color=trendColor1)

// 绘制买卖信号
plotshape(ma1 > ma2 and ma1[1] < ma2[1], style=shape.triangleup, color= color.rgb(59, 255, 108), size=size.small, text="多", location=location.belowbar,  title='买入信号', offset=1)
plotshape(ma1 < ma2 and ma1[1] > ma2[1], style=shape.triangledown, color= color.rgb(255, 0, 0), size=size.small, text="空", location=location.abovebar,  title='卖出信号', offset=1)

// 计算下单数量与执行入场逻辑
mainComment=str.tostring(high[1])
strategyAmount=investment/close
longCondition = ma1 > ma2 and ma1[1] < ma2[1]
if (longCondition and afterStartDate)
    strategy.entry("多单", strategy.long, qty=strategyAmount, comment = mainComment)

shortCondition = ma1 < ma2 and ma1[1] > ma2[1]
if (shortCondition and afterStartDate)
    strategy.entry("空单", strategy.short, qty=strategyAmount, comment = mainComment)

// --- 新增止盈止损平仓逻辑 ---
// 获取持仓平均入场价
entryPrice = strategy.position_avg_price

// 多单平仓条件：上涨3%止盈 / 下跌1%止损
longTakeProfit = close >= entryPrice * (1 + takeProfitPerc / 100)
longStopLoss = close <= entryPrice * (1 - stopLossPerc / 100)

// 空单平仓条件：下跌3%止盈 / 上涨1%止损
shortTakeProfit = close <= entryPrice * (1 - takeProfitPerc / 100)
shortStopLoss = close >= entryPrice * (1 + stopLossPerc / 100)

// 执行平仓操作
if (strategy.position_size > 0 and (longTakeProfit or longStopLoss))
    strategy.close("多单", comment="止盈/止损平仓")

if (strategy.position_size < 0 and (shortTakeProfit or shortStopLoss))
    strategy.close("空单", comment="止盈/止损平仓")

关键逻辑说明： #

• 参数化配置：新增可调整的止盈止损百分比参数，方便后续测试不同比例效果
• 持仓均价获取：通过strategy.position_avg_price获取当前持仓的平均入场价，确保盈亏比例计算准确
• 多单规则：持仓后价格较入场价上涨3%触发止盈，下跌1%触发止损
• 空单规则：持仓后价格较入场价下跌3%触发止盈（做空盈利逻辑），上涨1%触发止损
• 精准平仓：通过订单名称指定平仓对象，避免误平其他方向持仓
