Bigger timeframe RSI
Alexander.Gettinger · Mon May 03, 2010 11:25 pm
This indicator applies the RSI on the data of the same instrument but in bigger timeframe (for example week candles on day chart).
The indicator was revised and updated

Thanks Alexander, very usefull for me. Do you think it is possible to make the same indicator with Williams%R (instead RSI)? Thanks a lot. Sergio

Bigger timeframe Williams Percent Range (WPR).

For this indicator must be installed Williams Percent Range (WPR) indicator (viewtopic.php?f=17&t=898&p=1640).

Thank you Alexander, great job.
Could i have a version of this indicator that allows me to zoom the RSI so that i have a range between 30 to 70 (for example) displayed? I dislike the default range from 0 to 100, cause i don’t see properly the zone that i care more about, the 40-60 one.
Thank you very much

Try Updated Version.
FYI. We have ceased to provide support for Bigger time frame Indicators. As TS now supports this functionality.
