This is a simple indicator that displays a trend relative to the current day.
It should be used only on H4 or smaller timeframes.
The red line stands for the bearish trend, while the blue line means the bullish one. A moving average of a larger period specified in the parameters is used to track the overall trend. The second line works from the current day.
If you focus on the second line while a signal appears on the first one, you may decrease the parameter down to 8 to enter the marker earlier.
