High/Low Weekly Timeframe

I'm testing a simple but useful indicator that plots the high and low for the current week. The time-frame can be selected by the user.

It's useful when you're trading in a smaller time-frame (example: 1H or 4H) to know exactly the weekly low and high, and whether the price breaks above or below this price lines.

This indicator allows you:
- To select the desired time-frame to get the Low and High.
- To print an optional EMA for the same time-frame.
- To optionally change the bar-color when the close price crosses above the weekly high or crosses below the weekly low.

Hope this helps you to visually identify price movements.

If you like this script please give me a like and comment below.

Thanks,
Rodrigo
