Library "distance_ratio"
Collection of types and functions that can be used for the calculation of the ratio [0, 1] of a distance
from a barrier price using several methods. Methods supported are percentagewise (PERC), atr-based (ATR), fixed
profit (PROF), tick-based (TICKS), risk reward ratio (RR) and local extrema (LOC).
This library is meant to replace my previously published "distance_percentile" library since it offers a more intuitive interface by using the method syntax.

v2
Use method syntax for "long_biased_dist_ratio" and "short_biased_dist_ratio".
For types use PascalCase instead of camelCase to work around some compiler errors as Stratfather suggested.

v3
Some optimizations in the PROF method calculations

v4
  • Add Standard Deviation method for distance and LOC margin
  • More accurate PROF calculation formula with commission fees
릴리즈 노트
v5
Add step logic to stdev method by adding multipliers
릴리즈 노트
v6
Simplify exit commission fee calculation
릴리즈 노트
v7
Add initial entry fees in the PROF calculation

v8
(minor) without base quantity
릴리즈 노트
v9
Use barrier as the entry price for the stepped fixed profit calculations that are also scaled with the price movement when there are consecutive price targets

v10

  • Added price and ticks methods
  • Added separate restrict methods
  • Simplified the object types
  • Removed the bias logic in the LOC method
릴리즈 노트
v11
  • Tick related methods not return an integer
  • If there is a not defined value during calculations return an error if fatal or zero otherwise
  • Remove restrict argument from "pure" ratio, price ticks calls
릴리즈 노트
v12
Update some documentation and fixed a typo in the error message
릴리즈 노트
v13
  • Updated documentation
  • Use force_overlay for the example plots
릴리즈 노트
v14
  • Use enum where possible
릴리즈 노트
v15
Update to pinescript version 6
릴리즈 노트
v16
  • Pass the stop loss distance instead of ratio
  • Update the example
