Dynamic risk-reward lines

Hello All

For my short-term trading, I'd like to be able to quickly assess risk:reward, using lines on the chart.

This will be a combination of "Spread Info" and "Blue Spread" (as available from Code Base) - with modifications/enhancement. 

Crucially, these lines would need to dynamically adjust to price levels, by default - with the option to set at fixed levels.

 Parameter settings: 

• Line colour and style
• Upper and lower line price-levels: (fixed or dynamic)
  
  Dynamic:
  
  
• Upper-line distance, as a multiple of spread 
• Upper-line distance, as a multiple of Lower-line distance
• Lower-line distance, as a multiple of spread
• Upper-line distance, as a multiple of Upper-line distance
