//|                                              Real Woodie CCI.mq4 |
//|                Based on the code of Jason Robinson (jnrtrading). |
//|                                                                  |
//| After read the Woodie introductory document I started a search   |
//| for the right coloured CCI.                                      |
//| I can´t find anyone in accomplish with the explanation of Woodie |
//| So, I take the code from another CCI, and I added                |
//| the center LSMA line according to the official explanation.      |
//| Everything you see is an exact copy like it´s explained in the   |
//| document new_woodie_do1. Specially the colors.                   |
//| If you have some doubts can obtain a copy                        |
//| from http://woodiescciclub.com/                                  |
