//|  I found the original indicator in TSD forum posted by heliyaun. |
//|                                       I don´t know how wrote it. |
//| I like it because have mondays fixed for broker with GMT outside |
//| london time.                                                     |
//| So, I added some stuff, labels, fix, etc. and them, I wrote the|
//|             Medians SR, and then, I wrote the same for Monthlies |
//|                                                                  |
