PINE LIBRARY

distance_ratio

已更新

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.

版本注释

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.

版本注释

v3
Some optimizations in the PROF method calculations

版本注释

Add Standard Deviation method for distance and LOC margin
More accurate PROF calculation formula with commission fees

版本注释

v5
Add step logic to stdev method by adding multipliers

版本注释

v6
Simplify exit commission fee calculation

版本注释

v7
Add initial entry fees in the PROF calculation

版本注释

v8
(minor) without base quantity

版本注释

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

版本注释

v10

Added price and ticks methods
Added separate restrict methods
Simplified the object types
Removed the bias logic in the LOC method

版本注释

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

版本注释

v12
Update some documentation and fixed a typo in the error message

v13
