This script allows you to change a template and a timeframe on all open charts.
By default, a template name (Name of Template) is set to <SetCharts>.
You can create your template setting with this name and save it to use easly or select any template name you like.
If you select other name than a default one, you have to write it any time.
The good way to change timeframe is to simply set a needed timeframe before the launch and leave the current setting for the timeframe.
This demo script set automatically time frame to 15M! You can find it for all time frames at low price of 10 USD.
Now it works very well.
