Building an Expert Advisor to draw and manage a Fibonacci retracement


The Fibonacci Trader Plug-in can programatically draw a trend line on a price chart using the fnDrawFibo function.


To build an Expert Advisor that opens a BUY trade when a programatically drawn Fibonacci retracement level has been broken, refer to the drawing below:









Four coordinates are required to draw a line in two dimensional space.  For example, on a typical graph, using the Cartesion coordinate system, the coordinates are usually defined as (x1, y1) and (x2,y2).


The primary coordinates of the trend line are defined as the StartBar, the StartPrice, the EndBar and the EndPrice.
