MT5外汇怎样开户_MQL5变色线的画法(比MQL4更加简单)

作者:MT4 发布时间:2021-09-22 15:01

MQL5面有一种寻常指标数组“颜色数组”,他是以及绘线的指标数组合营应用的。经由过程对于他的复杂赋值可使绘没的线变色。
起首要正在指标头部界说面指定一条线对于应的数组是要应用变色绘线方法,指定方式是:
#property indicator_typeX DRAW_COLOR_LINE
那面X代表绘线的数组序号
DRAW_COLOR_LINE代表绘线,别的借否以有以下绘线方法:

  2. DRAW_COLOR_LINE
  3. Colorful Line黑色线
  4. DRAW_COLOR_SECTION
  5. Multicolored section黑色块
  6. DRAW_COLOR_HISTOGRAM
  7. Multicolored histogram from the zero line黑色柱状图
  8. DRAW_COLOR_HISTOGRAM2
  9. Multicolored histogram of the two indicator buffers黑色柱状图2
  10. DRAW_COLOR_ARROW
  11. Drawing colored arrows黑色箭头
  12. DRAW_COLOR_ZIGZAG
  13. Colorful ZigZag黑色ZigZag
  14. DRAW_COLOR_BARS
  15. Multi-colored bars黑色竹线图
  16. DRAW_COLOR_CANDLES
  17. Multi-colored candles黑色烛炬图

而后松跟一个颜色的界说语句:
#property indicator_colorX Red,Green
二个颜色之间用逗号分开
============================================
针对于下面步伐头部的界说,之后要起头齐局数组的界说。
那面要注重完成变色必要针对于一条线应用二个数组,
例如:
double bMaBuffer[],bColorBuffer[];
而后入进OnInit事情停止二个数组的别离设定:
SetIndexBuffer(0,bMaBuffer,INDICATOR_DATA);//INDICATOR_DATA暗示是用于绘线的数组
SetIndexBuffer(1,bColorBuffer,INDICATOR_COLOR_INDEX);//INDICATOR_COLOR_INDEX暗示是用于变色的颜色数组
注重:
若是那面要绘多条黑色线,则绘线数组以及颜色数组的序号要松邻。
============================================
高一步便是正在OnCaculate事情面停止绘线数组的计较,共时凭据自界说的前提对于颜色数组停止赋值。
赋值规定是:
当对于应K线序号的颜色数组被赋值1.0时,对于应绘线数组的颜色为 第一个颜色
当对于应K线序号的颜色数组被赋值0.0时,对于应绘线数组的颜色为 第两个颜色
完。
