EXPERT ADVISOR PROGRAMMING
Appendix C
Expert Advisor with Functions
This is the expert advisor using the functions introduced in chapter 4. We've added the "close all
orders" functions and trailing stop function from chapter 5, and the "execute once per bar" features
from chapter 7.
The functions are defined in IncludeExample.mqh, the contents of which are listed in Appendix D.
