如何在多个时间范围内搜索烛形图 [英] How to search for a candlestick pattern on multiple timeframes

问题描述

我有一个专家顾问，他在一个特别定义的看跌Pinbar上绘制矩形，然后看涨蜡烛.请参见下面的代码.它基本上在图表上显示的时间范围内显示矩形.

I have an expert advisor that draws rectangle on a specifically defined bearish pinbar followed by a bullish candle. Please see the code below. It basically shows the rectangle on the timeframe displayed on the chart.

如何在H1烛台直至M2内的时间范围内搜索该烛形模式，以便可以从所有时间帧中筛选出具有最长看跌针形的模式?

How can I search for this candlestick pattern on timeframes within an H1 candlestick down to M2 in such a way that I can filter the pattern that has the longest bearish pinbar from all timeframes?

推荐答案

1. 声明所有必要的时间范围ENUM_TIMEFRAMES tfs[];
2. 将其填充到OnInit()中，然后遍历值:for(int i=ArraySize(tfs)-1;i>=0;i--){showPinbarRectOnDispTime(tfs[i]);};
3. 编辑showPinbarRectOnDispTime(ENUM_TIMEFRAMES tf)函数:double barOpen = iOpen(_Symbol,tf,i + 1);，依此类推；
4. 考虑是否只需要绘制针形矩形或以某种方式消耗该数据而无需绘制.

1. declare all the necessary timeframes ENUM_TIMEFRAMES tfs[];
2. fill it in OnInit() then loop over values: for(int i=ArraySize(tfs)-1;i>=0;i--){showPinbarRectOnDispTime(tfs[i]);};
3. edit the showPinbarRectOnDispTime(ENUM_TIMEFRAMES tf) function: double barOpen = iOpen(_Symbol,tf,i + 1); and so on;
4. think whether you need just to draw the pin bar rectangles or somehow consume that data without drawing.
