distance_ratio

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.
Notes de version
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.
Notes de version
v3
Some optimizations in the PROF method calculations
Notes de version
v4
  • Add Standard Deviation method for distance and LOC margin
  • More accurate PROF calculation formula with commission fees
Notes de version
v5
Add step logic to stdev method by adding multipliers
Notes de version
v6
Simplify exit commission fee calculation
Notes de version
v7
Add initial entry fees in the PROF calculation
Notes de version
v8
(minor) without base quantity
Notes de version
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
Notes de version
v10

  • Added price and ticks methods
  • Added separate restrict methods
  • Simplified the object types
  • Removed the bias logic in the LOC method
Notes de version
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
Notes de version
v12
Update some documentation and fixed a typo in the error message
Notes de version
v13
  • Updated documentation
  • Use force_overlay for the example plots
Notes de version
v14
  • Use enum where possible
Notes de version
v15
Update to pinescript version 6
