pine-script - 如何使用 Pine 编辑器在 Tradingdview 中导入交易历史记录？

Question

我正在尝试将一些购买和销售导入到图表中。理想情况下，我想标记蜡烛并显示数量，但我有两个问题。

第一个是当我添加很多交易(大约 50 个)时，我不断收到“数组太大。最大大小为 100000”，第二个是我不知道如何显示金额。

我用谷歌搜索了一下，这是我设法编写的代码，但如前所述，它不起作用。

不是多头或空头策略，我只需要将买入和卖出移动到图表中

Answer 1

您超出了数组限制，因为您不必要地将交易数据添加到每个柱的数组中。使用 var 数组，您只需执行一次。在 if barstate.isfirst 中嵌套 add_trade() 调用或使用 array.from()

var int[] when_buy = array.from(timestamp('2021-06-01'), timestamp('2021-05-27'), 等等....)

要显示金额，请使用 label.new()

if array.includes(when_sell, ts_today)
    order := -1
    idx     = array.indexof(when_sell, ts_today)
    amount   := array.get(total, idx)
    label.new(x = bar_index, y = high, style = label.style_label_down, color = color.red, textcolor = color.white, text = tostring(amount))
