[L] MTF SSL Channel

This indicator plots SSL Channel, ideally from an higher time frame. I couldn't find any SSL Channel script with this feature so I made one, hope that helps others.

Features:

No Repainting
The script does not repaint and follows Pinescripters' guidelines.

Other Time Frame
It is possible to select another (higher) time frame. If a lower one is selected the script warns to change it, since calling a lower time frame leads to unreliable data.

Alerts
It is possible to create alerts for trend changes (cross Up or Down).

It also shows simple labels to see trend status at glance.

Notes de version:

- "Use other time frame" has been made optional; you can use it in the same resolution as the chart in a more reliable way (leaving the option un-checked instead of setting "Same as chart" will avoid smoothing).
- Added SSL Channel background (can be disabled in the Style Settings)
- Added option to show\hide SSL Cross labels and Trend Status information

Notes de version:

- Code clean-up
- Updated to latest Pine version
- Updated graphics and style options

Notes de version:

Notes de version:

Updated with optional label style (Color \ Dark)
