Remove multiple Pine Script indicators: SSFDSP, STARCHANNEL, STBANDS, STC, UBANDS, UCHANNEL, VWAPBANDS, and VWAPSD. These indicators were deleted to streamline the library and remove unused or redundant code.

+//@function Calculates TD Sequential — Tom DeMark's exhaustion counting system
+//@param comparePeriod Lookback for setup comparison (close vs close[comparePeriod])
+//@returns [setupCount, countdownCount] signed setup (1-9) and countdown (1-13) values
+//@description TD Sequential identifies trend exhaustion via two phases:
+//  Phase 1 — Setup (1 to 9):
+//    Buy Setup: consecutive bars where close < close[comparePeriod] (count negative)
+//    Sell Setup: consecutive bars where close > close[comparePeriod] (count positive)
+//    A completed setup reaches ±9. The count resets when the condition breaks.
+//  Phase 2 — Countdown (1 to 13):
+//    After a completed 9-count setup, countdown begins:
+//    Buy Countdown: close < low[2] (counts negative, toward −13)
+//    Sell Countdown: close > high[2] (counts positive, toward +13)
+//    Countdown is non-consecutive — only qualifying bars increment.
+//    Countdown resets if an opposite setup completes (±9 in other direction).
+//    A completed ±13 signals potential exhaustion reversal.
+//  Setup values: −9 to −1 (buy) or +1 to +9 (sell), 0 = no active setup bar
+//  Countdown values: −13 to −1 (buy) or +1 to +13 (sell), 0 = no active countdown
+//  The oscillator output combines both: setup during phase 1, countdown during phase 2.
+//  All state is O(1) via var scalars — no buffers needed.
