A walkthrough of a TradingView Pine Script implementation of the MTF RVOL concept.
Educational — the script is an indicator, not a trading system.
What the Script Does
`MTF RVOL Pro v4` is a Pine Script (v6) indicator that plots Relative Volume across **six
timeframes** on one chart:
It overlays effort/result scoring, support/resistance proximity (in ATR units), and a
Volume Profile (VPOC) layer, then exposes a strategy engine for signal generation.
The Repainting Problem (and the v4 Fix)
Repainting happens when an indicator uses `lookahead` or future bars, so signals appear
"perfect" in hindsight but vanish live. v4's changelog explicitly targets this:
Core Inputs
rvolLen = 20 // RVOL SMA length
effortThreshold = 0.12 // min effort to count as committed
rangeLookback = 20 // S/R range
supportNearAtr = 0.60 // near-level ATR distance
Why This Matters for Quant Research
A Pine Script is the *fastest* way to validate an idea visually before committing to a Python
backtest. The MTF RVOL concept — volume commitment across timeframes — transfers directly to
the 117-column Python feature set (see the `h1_trend`, `h1_vol_ratio`, `h1_range_ratio`
features). The indicator is the hypothesis; the ML pipeline is the test.
Honest Limitation
Pine Script cannot reproduce the options-surface or order-flow features (OI, PCR, greeks)
that the Python build uses. Treat the script as a **directional filter**, not a standalone
system. The real edge in the research build came from combining MTF context with options
data — something no single indicator captures.
