Not sure about that ADR indicator. It's just sitting there with a panel and nothing on the chart...maybe it's waiting for live data to begin. The author did say that this free version is not 100% accurate because it counts off days the same as live days. He does offer a paid version on the MQL5 market place that he claims is accurate

There is a Legacy of Gann indicator available on MQL5 for about $70.00, there is a free mt4 version somewhere on this forum. It is worth checking out.
The semafor indicator matches Xard's and the 2nd Dot indicators used by a lot of folks for mt4. I wish I could make them a little bigger though.
