+# Sirius Trading - Pine Scripts
+
+This directory contains custom algorithmic trading scripts designed for TradingView (Pine Script v5).
+
+## Scripts
+
+### 1. `SiriusAITrendMaster.pine`
+A robust, trend-following strategy designed for crypto and equities. 
+
+**Core Logic:**
+- **Entry:** Uses a Fast/Slow EMA crossover.
+- **Filter:** Validates momentum by requiring the price to be above/below the Volume Weighted Average Price (VWAP) before taking the cross.
+- **Risk Management:** Implements an automated, dynamic ATR-based trailing stop-loss.
+
+### 2. `SiriusMeanReversion.pine`
+A mean-reversion counter-trend strategy designed to catch over-extended moves in ranging markets.
+
+**Core Logic:**
+- **Entry:** Buys when the price crosses below the lower Bollinger Band and RSI is oversold (< 30). Shorts when price crosses above the upper Bollinger Band and RSI is overbought (> 70).
+- **Risk Management:** Uses strict percentage-based Take Profit and Stop Loss limits set via the script inputs.
