[NM]Improved Linear Regression Bull and Bear Power v02

Hi guys, I'm back with a little improvement on the Bull and Bear Signal I published just last week thanks to some feedback I received from a couple of users, which is of course highly appreciated.

Here are the changes that have been implemented compared to v01 :
(version 1 is the top indicator, version 2 is the bottom one) in the chart above

  • Formula adapted to calculate the signal if no data is available for either bull or bear
  • Added the possibility to smoothen the signal using Arnaud Legroux Moving Average (the benefit of this is that it does not add any lag to the signal)
  • Zero line was added

If you have any further ideas on how to improve the indicator or if you are happy with it and want to share your settings or rules of engagement, please feel free to share them below.

Hi Nico, @Nico.Muselle. Thanks for this script. I have adapted it by plotting another line for a long term resolution but I have observed that the color on the long term resolution line is not accurate on real time data as compared to historical data. Here is the code. Do you know how I can fix the problem?

All I can say is wow. . . I did a little manual back testing on UJ daily using the default settings, changed the chart to Renko , and added LazyBear's ZeroLagEMA you suggested in the code comments. Following your instructions in the code comments results in a very high Win %, Great RR on each trade, and a very simple system.

I do not have a PRO account. So, I am unable to test on any time frame lower than D but I imaging there will be more false signals/losses on lower time frames. However, if further analysis supports the signals, lower time frames may still be quite profitable.

Thank you for you hard work on this indi!
