I decided to search truth of trend power with and LinReg and found it in a somewhere of the middle. Also, I added a limit area, where you need to keep a more attention, because it can show a potential reversal.
You can change parametrs with a your own look.
One more signal for indicator:
- If "WOM" is above "1" - it's a direction;
- If "WOM" is below "1" - it's a direction.
