SSL Indicator

Description

The SSL indicator consists of two SMAs, one of the Highs,the other of the Lows.

On Close above High SMA, the indicator is Long, on Close below Low SMA, the indicator is Short.
The Long vs. Short is visualized by a red and a blue line.
When Long, the blue line is at the High SMA and the red line is at the Low SMA.
When Short, the red line is at the High SMA and the blue line is at the Low SMA.

Furthermore, transitions between Long and Short coincide with crossing of the red and blue lines.

Thanks for the update, but I just saw an SSL indicator has already been published. So I think I just remove mine.

Just an update to Bart's SSL Indicator which allows you to access variable types of Moving Averages.

Cheers
