User defined trendline points

  Hello All,

  I am trying to code an indicator that will draw a line between two points on RSI like I have attached in the screen shot.

  I am wondering what is the best way to tell ProBuilder the coordinates if my line?

  Once I have these I thought I might be able to duplicate this line by calculating the slope with rise/run so I can have duplicates of the line on the indicator.

  I hope this will also allow me to get the value of the line at any given point in time.

  Any advice would be greatly appreciated,

  Many thanks,

  Tim.

  Hi @tabarrington

  What are the conditions for these two points?

  Does the RSI have to be at a certain value or are only the dates of these points decisive?

  Hi JS,

  Thankyou very much for the reply!

  RSI and date have to be at a certain value…

  Ive played around with a few things like DATETOBARINDEX(2022022117) to stop the X coordinates moving when a new bar is loaded which does work but Ive been unable to define a variable using that…

  Is there a way that you know of for saving a set point in time, such as DATETOBARINDEX(2022022117), to a variable?

  Many Thanks!!

  I deleted all duplicates.

  Hi @tabarrington

  That’s right, you could use DateToBarIndex to draw your line between two dates and at certain levels.

  You then have to enter two dates, a start date and an end date.

  The indicator then draws the line between these two data and plots the values of the corresponding RSI.
