Statistics indicators
The 13 built-in statistics indicators Vike Trader ships, with every parameter, its default and its sweep range — rendered from the indicator registry.
Statistical indicators are the regression, correlation and distribution kernels — the raw material of a research feature set. Vike Trader ships 13 of them in this category, out of 171 built-in single-series indicators and 8 pair indicators; the indicators overview carries the catalog's shape and the categories side by side.
Every built-in indicator carries one guarantee: its streaming on_bar path equals its batch
vectorize kernel bit-for-bit, proven by the parity gate in the product tree
(crates/vike-indicators/tests/parity.rs). The exceptions are declared, not discovered: an
indicator marked batch-only reads future bars in its batch form, so its streaming value is a
causal best-effort that is NaN at the unknowable tip, and the gate skips it by name. No indicator in this category is batch-only.
Indicators
Each parameter is shown with its built-in default and the range and step the Studio's sweep grid
offers for it (ParamSpec in vike_indicators::registry).
| Id | Name | Parameters (default; range, step) | Batch-only |
|---|---|---|---|
linearreg | Linear Regression | period = 14 (2–200, step 1) | no |
linearreg_slope | Linear Reg Slope | period = 14 (2–200, step 1) | no |
linearreg_angle | Linear Reg Angle | period = 14 (2–200, step 1) | no |
linearreg_intercept | Linear Reg Intercept | period = 14 (2–200, step 1) | no |
tsf | Time Series Forecast | period = 14 (2–200, step 1) | no |
var | Variance | period = 20 (2–200, step 1) | no |
zscore | Z-Score | period = 20 (2–200, step 1) | no |
skew | Skewness | period = 20 (2–200, step 1) | no |
kurtosis | Kurtosis | period = 20 (2–200, step 1) | no |
mad | Mean Abs Deviation | period = 20 (2–200, step 1) | no |
std_error | Standard Error | period = 20 (2–200, step 1) | no |
std_error_bands | Std Error Bands | period = 20 (2–200, step 1); mult = 2 (0.1–10, step 0.1) | no |
rank_correlation | Rank Correlation | period = 14 (2–200, step 1) | no |
Using them
In a Rhai strategy an indicator is a call by id with its
parameters in registry order — linearreg(…) — and the Studio's
indicators pane offers the same catalog with each parameter's
sweep range pre-filled from the defaults below. From Rust, vike_indicators::make(id) builds the
default instance and make_with(id, ¶ms) the parameterised one; both consult the same
registry row this table was rendered from.
