Pine脚本-有没有什么功能可以检查某个订单是否已经填满？

//@version=4
strategy("Order Fill Check", overlay=true)

// 检查某个订单是否已经填满
isOrderFilled(orderId) =>
    closedTrades = strategy.closedtrades
    for i = 0 to (array.size(closedTrades) - 1)
        if closedTrades[i][0] == orderId
            return true
    false

// 示例使用：检查订单号为123的订单是否已经填满
orderId = 123
orderFilled = isOrderFilled(orderId)
plot(orderFilled ? 1 : 0, title="Order Filled", color=color.green, style=plot.style_histogram)
