Rebound V-Fib RT

Rebound V-Fib RT
A lightweight, real-time variant of Rebound V-Fib for normal (linear) price charts. It draws the slanted V-Fib, support line, V-Ladder and baseball runner, marks trend entries, and exposes trend/support readouts - fast enough for second-scale charts and the Pine Screener.

For US equities on intraday/daily timeframes. Adjust 'Trading hours per day' for other markets (default 6.5).

Drawing-focused: there is no back-test, technical rating, support/exit signal, trailing stop, or lower-timeframe request. Trend geometry and rates update every bar; support detection and all drawing run on the last bar. Signals and drawings update on the live bar and confirm at close (they repaint intrabar) - for confirmed-only entry alerts, choose "Once Per Bar Close".

DIFFERENCES FROM Rebound V-Fib

Adds the V-Ladder (key Fib levels along the support direction) and the baseball runner (emoji marking how far price has run up the ladder)
Trend entry is shown as a single entry-bar background tint plus an alert, computed from the live bar's rates / V-Fib / lead - no back-test, no support entry, no exit, no trailing stop
Detection works before a full Lookback bars of history exists, so it draws on short histories and in Bar Replay
Tuned for real-time use and Pine Screener filtering rather than historical simulation

OUTPUTS

Overlay:

Slanted Fib band (multi-colored levels), blue uptrend line, purple support diagonal
V-Ladder - purple key levels (0.236 / 0.5 / 1.0 / 1.618 / 2.272 / 3.0) between the previous and current support
Baseball runner - emoji above the first bar that reached each V-Ladder level
V-Fib Ratio label on the last bar
Entry-bar background tint (blue) when a trend entry is marked

Status line + Data Window + Screener:

V-Fib - current V-Fib Ratio (position on the slanted Fib band; the value equals the Fib level number)
V-Trend - net rate (Up + Down), %/day
Sup%/d - support slope, %/day

Data Window + Screener:

Age - bars since the current trend entry (0 when not in a setup). Recommended Pine Screener filter: Age 1 ~ 7
SupAge - days since the current support line was established
SupLead% - close above support, as % of close
Lead% - leading days x uptrend rate. Leading days = days the current price is ahead of / behind the uptrend baseline
Up%/d, Down%/d - trend slopes, %/day

Note: Pine Screener is limited to 500 bars of history; the support readouts (SupAge, Sup%/d, SupLead%) are computed on the last bar only.

INPUTS

General:

Lookback bars - V-shape detection window
Trading hours per day - intraday day-to-bar conversion for the %/day readouts (6.5 = US equities)

Trend detection:

Min downtrend bars / Min uptrend bars - minimum bars from top to V-bottom / from V-bottom to now

Trend entry:

Min uptrend rate - reject if uptrend slope is below this (%/day)
Max downtrend rate - reject if downtrend slope exceeds this (typically <= 0)
Min V-Trend - reject if Up + Down rate is below this
Min / Max entry V-Fib - lower / upper bound of the entry window on the slanted Fib band
Min entry leading gain - minimum Lead% required at entry
Unlock V-Fib - re-arm the entry once V-Fib rises past this (one signal per setup)

Display:

Show baseball runner - toggle the V-Ladder emoji
Show trend entry - toggle the entry-bar background tint
