MetaTrader:指标缓冲区数量少于需要
MetaTrader: indicator buffers amount is less than needed
我在 MetaTrader 中编译时遇到这个错误:
indicator buffers amount is less than needed
有什么帮助吗?
这似乎是一个问题:
#property indicator_buffers XXX //How Many Plots
XXX 应该是 Buffers/plots
的正确数量
MQL4 指标设置可能看起来像一个双头噩梦。
也许是,
也许不是:
指标设置有两种主要方法。
一个,使用#属性 ...语法接口,
和
另一个,使用函数调用...
这两个为什么存在?它们如何共存?
#property ...
indicator_chart_window Show the indicator in the chart window
indicator_separate_window Show the indicator in a separate window
indicator_height int Fixed height of the indicator subwindow in pixels (property INDICATOR_HEIGHT)
indicator_buffers int Number of buffers for indicator calculation
indicator_minimum double The bottom scaling limit for a separate indicator window
indicator_maximum double The top scaling limit for a separate indicator window
indicator_labelN string Sets a label for the N-th graphic series displayed in DataWindow
indicator_colorN color The color for displaying line N, where N is the number of graphic series; numbering starts from 1
indicator_widthN int Line thickness in graphic series, where N is the number of graphic series; numbering starts from 1
indicator_styleN int Line style in graphic series, specified by the values of ENUM_LINE_STYLE. N is the number of graphic series; numbering starts from 1
indicator_typeN int Type of indicator drawing style. N is the number of graphic series; numbering starts from 1
indicator_levelN double Horizontal level of N in a separate indicator window
indicator_levelcolor color Color of horizontal levels of the indicator
indicator_levelwidth int Thickness of horizontal levels of the indicator
indicator_levelstyle int Style of horizontal levels of the indicator
在使用 MQL4 一段时间后,您将采用自己最好的方式前进。
为什么工作失败?
简短版本:编译时决定设置为指标时间序列对齐数据预设的数组数量。超过这个设定的上限则必须抛出异常,因为没有进一步的缓冲区来存储数据。
但是,先设置一个更大的上限是可能的,并且可能有助于在以后的某个时间仍然 space 足够,即使您现在不使用它也是如此。
