A 5 week CMO would sample data only on the last day of the week. This is not quite as straightforward as one might think, but it can be done. First one needs to have an accurate breakdown of how the CMO is constructed. I have some code that appears to be the prerequisite for a normal data array so I'll take it further when I get a moment (24-48 hours). Roy Here is the standard CMO (source unknown). |

From that indicator structure a weekly CMO for daily charts can be constructed. The following example does NOT have a dynamic current week, and neither will it update until Monday data is added if Friday data is missing. Both of these issues can be easily addressed but for normal over-the-weekend analysis this indicator will return the weekly CMO value when used in daily explorations. Please understand that this is not intended to be the ultimate solution but it is simply an example of a basic weekly CMO for daily charts. Roy | ||||
