Volume indicators
The 14 built-in volume indicators Vike Trader ships, with every parameter, its default and its sweep range — rendered from the indicator registry.
Volume indicators fold traded quantity into the picture — accumulation, flow and volume-weighted prices. Vike Trader ships 14 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).

vwap | VWAP (session) | none | no |
obv | On-Balance Volume | none | no |
ad | Accumulation/Distribution | none | no |
adosc | Chaikin A/D Oscillator | fast = 3 (2–50, step 1); slow = 10 (2–200, step 1) | no |
cmf | Chaikin Money Flow | period = 20 (2–200, step 1) | no |
efi | Elder Force Index | period = 13 (2–200, step 1) | no |
eom | Ease of Movement | period = 14 (2–200, step 1) | no |
kvo | Klinger Volume Oscillator | fast = 34 (2–200, step 1); slow = 55 (2–500, step 1); signal = 13 (2–100, step 1) | no |
mfi | Money Flow Index | period = 14 (2–100, step 1) | no |
net_volume | Net Volume | none | no |
nvi | Negative Volume Index | none | no |
pvi | Positive Volume Index | none | no |
pvt | Price Volume Trend | none | no |
volume_osc | Volume Oscillator | short = 5 (2–50, step 1); long = 10 (2–200, step 1) | no |
Using them
In a Rhai strategy an indicator is a call by id with its
parameters in registry order — vwap(…) — 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.
