Data from array only exists for current bar. How can I reference historical values?

问题

以下是您提供的代码的翻译部分：

  1. 脚本在当前K线上打印了两个标签。这些标签是突破关键水平的看涨和看跌概率。我已将这些字符串拆分，只提取百分比字符串值，并转换为浮点数值，以便可以使用它们创建规则。这些浮点数存储在它们各自的变量"bull_prob"和"bear_prob"中。
  3. 问题在于这些变量只包含当前K线的数据，在历史K线上都是零值。我创建了两个新数组bull_hist[]和bear_hist[]，并将当前K线的值推送到它们，以便可以在历史上引用它们。当我检查数组大小时，我可以看到它已经推送了所有历史K线的值。然而，除了最后一个索引之外，它们仍然都是零值。
  5. 为了测试，我创建了基本的指标规则，简单地表示在看涨蜡烛上买入，在看跌蜡烛上卖出，但也考虑了概率规则是否成立。
  7. 当前结果：指标仅在当前K线上正确运行。这意味着在实时或回放期间，规则会适当处理。但除非回放，否则无法看到任何过去的指标。这也意味着如果我将其转换为策略，它将找不到任何交易。
  9. 预期结果：bull_prob和bear_prob应该显示在数据窗口中看到的那个K线上的概率值。我目前正在将它们的输出绘制到数据窗口中。以前的指标应该在图表上可见。

希望这有助于您理解代码的翻译部分。如果您有任何进一步的问题或需要进一步的帮助，请随时提问。

英文:

The script prints 2 labels on the current bar. These labels are the bullish and bearish probabilities of breaking a key level. I have split these strings to pull out just the percentage string value and converted to float values so that rules can be created with them. These floats are stored in their respective variables "bull_prob" and "bear_prob".

The problem is these variables only have data on the current bar and zero values on historical bars. I created 2 new arrays bull_hist[] and bear_hist[] and push the current bar value to them so that they can be referenced historically. When I check the array size I can see that it has pushed values for all historical bars. However they are still all zero values except for the last index.

For testing I have created basic indicator rules that simply indicate buy on a bull candle and sell on a bear candle, but also considers if the probability rule is true.

Current result: Indicator works correctly for the current bar only. This means that while live or during replay the rules are processed appropriately. However you cannot see any past indicators unless you replay. This also means if I convert this to a strategy it would find zero trades.

Intended result: bull_prob and bear_prob should show the probability value that existed on that bar as seen in the data window. I'm currently plotting their output to data window. Previous indicators should be visible on the chart.

I have tried more things than I can count or remember. I an not set on any particular method. Any way that can produce the intended result is fine by me “数组中的数据仅存在于当前柱形。如何引用历史数值？”

答案1

得分: 0

使用for循环和array.get(id, index)来获取数组的历史数值。

英文:

Use for loops and array.get(id, index) to get the historical values of the array.
