Custom Multi-Timeframe Indicator

It's a pretty simple example of a nice custom screener you can run for multiple timeframes. This is an RSI screener, but you can easily change the function for your own Indicator.
Screener displays:

• Last value of the instrument
  
• RSI value for up to 10 instruments / 4 timeframes.
  

In Parameters you can change:

• 4 timeframes
  
• 10 instruments
  
• Parameters for RSI
  
• Styling parameters for table
  

If the selected timeframe will be lower than the current one you will receive a warning message in a table.

Thanks to @MUQWISHI to help me code it.
