Based on TradingView's built-in Auto Fib Retracement code, how to calculate and plot the price difference between 0 and 1. I cannot figure out how and where to grab the price value of these Fibonnacci levels in the pinescript code.
Example from the linked image : I'd like the indicator to minus 6737,7 (level 0) to 6710,2 (level 1) which gives 27,5.
Thanks !
