Indicator idea based on classic Bollinger bands and Telson T8 moving average. The indicator detects Bollinger bands narrowing which should predict a move to a direction.
NOTE: You need to define in the indicator settings (Narrow percentage) the percentage between the upper and lower bands that would be highlighted. For example: if you set 5%, the indicator will highlight the parts that the upper and lower bands are less than 5% compare the current price (usually close price, but you can define otherwise)
Use the Telson T8 to determinate the trend/direction of the move.
