Basic Echo Ray Draggable Anchor
This is a price deviation / echo / replication band tool built in Pine Script v6, centered around a user-draggable vertical anchor line (time-based starting point).Main idea:You choose one anchor point in time (drag the vertical dashed blue line)
At that exact moment the indicator "freezes" / snapshots selected moving averages (of high/low/close)
It then creates a grid of horizontal rays extending to the right, based on symmetrical echo/deviation distances calculated from that snapshot
The echo size can grow or shrink either linearly (percentage mode) or via repeated square-root compression (very popular in some harmonic / fib-like crypto & forex setups)
Core calculation modesMode
Echo / deviation formula
Typical character
Common use-case feeling
Square Root
scale × √(√MA)
very compressed at higher prices
crypto, logarithmic feel, mean-reversion
Percentage
scale × start% × MA
classical linear percentage bands
stocks, forex, more traditional range
Most important levels drawn as rays (from anchor)u0 / l0 → frozen lowMA / highMA themselves (thick yellow)
u0.5, u1, u2, u3, …, u14 → upper deviations (mostly red)
l0.5, l1, l2, …, l14 → lower deviations (mostly green)
thicker lines at ±4, ±8, ±12 (more visual weight)
mid (50%), mid25, mid75 (customizable quartiles-ish)
Typical use cases (2024–2026 trading context)Anchor-based mean reversion / range trading
→ Drag anchor to recent swing high/low / news event / session open
→ Trade fades / reversals when price reaches u2–u4 or l2–l4 rays
→ Very common on BTC, ETH 1h–4h–1D after big moves
"Echo" continuation / breakout filter
→ After strong trend starts from anchor, price walking along u4–u8 or l4–l8 rays is considered continuation
→ Break & close beyond u12 / l12 often treated as exhaustion or very strong acceleration
Square-root mode as poor-man's log-scale bands
→ On assets that show parabolic / exponential behavior (crypto, some small-caps, meme coins)
→ Square-root compression creates bands that feel "logarithmic-ish" without changing chart scaling
Session / news / event replay analysis
→ Place anchor at FOMC, NFP, ETF approval tweet, halving, etc.
→ See how price respected / ignored the echo grid in following days/weeks
Visual "magnet" & confluence finder
→ Combine with VWAP, volume profile, order blocks, fibs
→ Many traders watch when multiple rays + other levels cluster together
Quick summary – when people usually add this indicatorYou want custom-time-period fixed deviation bands (not rolling like regular Bollinger)
You like draggable anchor VWAP-style tools but want more levels / different math
You trade crypto or high-vol instruments where classical % bands become too wide too quickly
You want to quickly visualise "where would price be if it continued the same volatility pattern from X moment"
In short: draggable time anchor + snapshot MA + square-root or %-based deviation rays
→ modern evolution of fixed-level fib / ATR / percent bands with very strong community usage in 2024–2026 crypto & index futures spaces.
