//| History:                                                         |
//| 1.0 => Release version to the public                             |
//| 1.1 =>  bugs fixed by Dave (dmieluk@exemail.com.au):             |
//|         1) StopLoss was wrong;                                   |
//|         2) StopLoss was conflicting with each other;             |
//|         3) The is_able_to_continue is now much better coded;     |
//|         3.1) The is_able_to_continue now works on any pair;      |
//|         4) Now the errors have descriptions instead of numbers.  |
