"""
Rettangolo Runner - Esecuzione live della strategia RETTANGOLO.

Loop ogni 60s:
  1. Per ogni symbol in rettangolo_assets.csv (strategy=rettangolo)
  2. Calcola compute_signal() (rettangolo_strategy.py)
  3. Se c'è segnale LONG o SHORT:
     - Safety cap MAX_OPEN_POSITIONS (10 globale, già in rettangolo_config)
     - FIX 2026-07-21 Mattia 16:35: ANTI-DOPPIA LOCALE via signal_state.json (cooldown 4h)
     - Se gia' posizione aperta su quel symbol: skip
     - Altrimenti: set leverage 3x, market order, set SL/TP via set_trading_stop
  4. Logga tutto in rettangolo_runner.log

NON tocca file di config (rettangolo_assets.csv, rettangolo_config.py).
NON modifica posizioni esistenti (time-stop lo fa Pine via webhook).
