PineScript V5：止损保本更新是否独立于开仓条件waitForLong？

PineScript策略风控逻辑独立性问题

我开发了一款PineScript策略，满足指定条件时执行交易，最多可开立5笔交易，且首个止盈（TP1）触发后自动将止损（SL）更新至保本价。策略运行在5分钟K线周期，现有以下核心疑问：

若已开立5笔交易，后续K线未触发开仓条件waitForLong，位于开仓条件代码块内的止损保本更新逻辑是否仍能生效？
现有持仓的风控管理逻辑是否独立于新仓开立条件？即持仓建立后，后续K线未满足开仓条件时，是否仍会按原有SL/TP规则管理活跃持仓？

交易组记录逻辑

// 记录该交易组的入场价与触发标记
array.push(longEntryPrices, buyOrSellPrice)
array.push(longTP1Hit, false)

止损计算与开仓、风控逻辑

// 止损为最近5根K线的最低价
slLong = ta.lowest(5)

if waitForLong
    currentPrice := close
    buyOrSellPrice := currentPrice + continuationPrice
     
    // 记录该交易组的入场价与触发标记
    array.push(longEntryPrices, buyOrSellPrice)
    array.push(longTP1Hit, false)

    for i = 1 to 5
        if slLong > currentPrice
            slLong := longCandleLow - spreadValue
            longProfit := (buyOrSellPrice + ((buyOrSellPrice - slLong) * i))
        else
            longProfit := (buyOrSellPrice + ((buyOrSellPrice - actualSlLong) * i))

            strategy.entry("Long " + str.tostring(i), strategy.long, qty=RiskValue, limit=buyOrSellPrice, stop=slLong)

            // 若TP1触发，将剩余交易的止损更新至保本价
            if not array.get(longTP1Hit, array.size(longEntryPrices) - 1) and (high >=(buyOrSellPrice + ((buyOrSellPrice - actualSlLong))))
                breakevenPrice = buyOrSellPrice
                for j = i + 1 to 5
                    strategy.exit("Long Exit " + str.tostring(j), "Long " + str.tostring(j), sto=breakevenPrice)
                array.set(longTP1Hit, array.size(longEntryPrices) - 1, true)
