Auto Fib Extension Targets A-B-C MartenBG

Auto Fib Extension Targets A-B-C is a Pine v6 indicator that projects Fibonacci extension targets from the most recent validated A-B-C swing. It works in both directions and is designed for trend continuation planning and take-profit placement.

How it works:

Detects pivots with user-defined left and right bars.

Builds bullish swings from L-H-L and bearish swings from H-L-H.

Validates C by a retracement filter (min to max, relative to AB) and an optional HL or LH condition.

Projects targets from point C using C + r*(B − A) for uptrends and C − r*(A − B) for downtrends.

Draws levels 1.000, 1.272, 1.382, 1.618, optional 2.000, plus an optional 1.272-1.382 target zone.

Optionally shows dotted A-B and B-C segments for quick visual context.

Key settings:

Pivot sensitivity: leftBars and rightBars.

Correction validation: minRetr and maxRetr, HL or LH requirement toggle.

Level visibility: enable or disable each ratio and the target zone.

Extension length: horizontal extension in bars.

Visuals: toggle A-B-C segment display.

Why use it:

Fast projection of realistic continuation targets.

Clear confluence when extensions align with prior highs, liquidity pools, or S/R.

Works on any symbol and timeframe once pivots are confirmed.

Notes:

Pivots confirm after rightBars bars, so targets appear only once a swing is confirmed. This reduces repaint-like behavior typical for unfinished pivots.

No alerts are included by design. If you want alerts or manual A-B-C locking and click-to-select anchors, ask and I will add them.
