RBC Range Bar Chart

RBC 范围柱线图表 是一款经典范围柱线指标。本指标的功能是提供价格区间图表: 最高价/最低价区间是一个经典的用于分析的选项。它也有开盘价, 最高价, 最低价和收盘价。在第一个选项里, ;两个价格数值同时被分析, 而其它选项只使用一个。以往,范围柱线使用即时报价绘制,但由于即时报价数据未在服务器上提供,图表只可能基于标准时间帧的柱线数据。您应该记住,时间帧越大,图表越粗糙。本指标实现通过标准时间帧选择。

在首次运行时, 您应该按下 R 键 或等待在设置里指定的 'Update period chart'。这将初始化图表。如果指标给出拷贝错误,这意味着正在从服务器拷贝数据的过程中,这可能需要一些时间,您可稍后重试。

注:
  • 如果您选择了一个十分大的时间段来进行分析 (早于开始日期), 则图表需要很长时间, 因为事实上指标在开始阶段要从服务器上拷贝大量数据;
  • 当在策略测试员里进行测试时, 分析的开始数据应早于开始时间一周或一个月 (依赖指定的步长)。

指标设置

  • Magic number - 独有指标数字,如果同时运行多个指标此数字很有必要 (每个指标必须有自己的魔幻数字);
  • Period of the analyzed data - 指标基于不同时间帧的数据绘制图表 (更大的时间帧, 图表更粗糙);
  • Update period chart - 设置一个特定的更新时间,以避免每次报价都重新计算图表;
  • Start date analysis - 指标从指定的日期开始分析并制作图表;
  • Type price for building - 正如前面提到的,本指标可以基于不同的价格制作图表 (最高价/最低价, 开盘价, 最高价, 最低价, 收盘价);
  • Step - 十分重要的范围柱线参数, 它判断所需绘制的范围柱线的移动大小。

版本 1.1 - 2015.04.23
Added fast charting option (Online). The function performs charting without waiting for a bar closing. In other words, the current Bid/Ask price is used as a charting basis.

The initial charting is performed using history data (OHLC prices), while the further ones are performed depending on the price changes. The system of protection against incorrectly specified parameters has been improved.

Thus, the following parameters have been added:
- Type building - charting type:
1. Typical (one minute) - the same charting as in the previous version
2. Online (fast) - real-time charting based on Bid/Ask price
- Price for Online type building - price type for real-time charting:
1. Bid - Bid price
2. Ask - Ask price
- Protection on instability - protection against unstable work:
1. No (errors may occur) - no protection, errors are possible due to incorrect data
2. Yes (normal protection) - medium protection (there is a possibility of charting starting not from an initial date)
3. Yes (enhanced protection) - enhanced protection (chart end is displayed)

The following parameters are ignored after preliminary charting in Online mode:
- Period of the analyzed data
- Update period chart
- Type price for building

The following parameter is ignored in Typical mode:
- Price for Online type building

Attention! Remember the following while testing:
- 'Start date analysis' parameter should have a date that is earlier than the test start in the strategy tester.
- 'Step' parameter affects the charting rate and may cause an error if its value is small, while the initial date ('Start date analysis' parameter) is very early.
- 'Start date analysis' parameter affects the charting rate and may cause an error if its value is set to a very early date, while the step ('Step' parameter) is too small. This parameter also affects downloading history from the server and may suspend initial indicator operation notifying of that event by the error message (Copy error).
