I've been using the outside range of 2014 as my major levels. It's been quite technical in those regards.
In addition we use a chart that has many inputs and we like to see how it performs. Many of the inputs for the algo are based off the chart. The system takes different entries and exits off of it also.
A range..., within a range..., all built upon another range Why OP taking it diagonal (with the TLs / channels) - when should be taking it horizontal - until price says otherwise of course But then what do I know RN
