// Description:
// "gary Short CallSpread with Trend Filter" — protected release by GaryQuant.
// This indicator identifies short-entry related signals (S, S2, S3) and close signals (P)
// using EMAs, RSI (+ RSI MA), MACD histogram, SAR, SMA120 distance gate and a daily ATR-based
// spread size. A configurable multi-timeframe trend filter (default 15m) restricts or allows
// sell signals per defined rules. The script draws persistent spread boxes and labels on
// confirmed bars, provides alertconditions for confirmed signals, and exposes inputs for
// tuning. Published as Protected: source hidden, description provides sufficient explanation
// for moderation and user understanding without disclosing proprietary internals.
