Yet Another Bitcoin—Altcoin Season Indicator

This is the BTC dominance chart with a background colored in orange representing the Bitcoin season and in blue for the Altcoin season. If the BTC dominance line is inside the orange area we're most probably in a Bitcoin season, and if in the blue area, on Altcoin season.

To help identify short-term shifts in dominance the BTC dominance line is colored:

• if the BTC dominance line has the same color as the background it is overing, it agrees in the short-term with the season
  
• on the other hand, if the BTC dominance line color is different from the background, it means we might be experiencing a short-term shift in season direction
  

You may configure overextended levels as you like, and they are set by default to 40 and 70, for the Altcoin and Bitcoin season respectively.

NB. Better experience if used on daily chart or above.
