Terra FVG & iFVGs

Terra – FVG & iFVG (Fixed-TFs for lower TF viewing)

What it does

Detects classic 3-bar Fair Value Gaps (FVGs) on a fixed source timeframe (e.g., 1m).
Draws FVGs immediately (default white), then converts the same box to iFVG once fully mitigated by close (bull FVG → bearish iFVG color, bear FVG → bullish iFVG color).
Lets you view higher-TF logic on lower TF charts (e.g., see 1m levels on a 15s chart).
Optionally blind the indicator on higher TFs so it only shows at/below the source TF.

Key features

Fixed TF input: choose one source TF; drawings align across charts via xloc=bar_time.
FVG → iFVG conversion: automatic recolor on validation by close (no repaint tricks).
Extend right edge: project boxes N source bars into the future.
Independent caps: keep at most X FVGs and Y iFVGs (defaults 3 & 3).
Draw order toggle: iFVGs on top (default) or FVGs on top.
Opacity per type: separate transparency for FVGs vs iFVGs.
History cap (optional): limit total boxes shown; oldest are pruned safely.
Alerts (optional): fire on iFVG confirmation.

Inputs (quick reference)

Source Timeframe: e.g., 1 (1m) or 15S; toggle “Show on higher TFs” if you don’t want blinding.
Draw Order & Limits:
iFVGs on top (ON/OFF)
Max FVGs (default 3)
Max iFVGs (default 3)

How it works (logic)

On the source TF, detect 3-bar gap:
Bull FVG: high[2] < low
Bear FVG: low[2] > high
Draw FVG box immediately (white by default), anchored from candle #1 time to +N source bars.
During the validation window, if close crosses the opposite bound, convert to iFVG (recolor, preserve/extend right edge).
On lower TF charts, drawings are time-anchored and align 1:1.
