Blackflag FTS (Fast Trail System) is a published Pine variant of SuperTrend. It swaps standard true range for a 'modified' true range that adjusts for gaps and recent-bar extremes, then runs the usual ATR-band trailing-stop logic on top of it for slightly earlier flips than vanilla SuperTrend.
On top of the trend line, Blackflag tracks `ex` — the highest high since the last bull flip or the lowest low since the last bear flip — and projects Fibonacci retracement levels from `ex` back toward the trend stop (61.8%, 78.6%, 88.6%). Those Fib lines are intended as pullback entry zones inside the active trend.
Use it the same way as SuperTrend, but treat the Fib levels as 'where to re-enter after a pullback' rather than as standalone reversal signals.
Example
Bull flip at 49,500; price rallies to ex = 52,000. The 61.8% retracement = 50,547 — a common pullback entry zone before the next leg, with the SuperTrend stop as invalidation.
