Engulfing & Pin Bar Breakout Strategy
ลิงก์ TradingView
คำอธิบาย
Overview
This strategy automates a classic, powerful trading methodology based on identifying key candlestick reversal patterns and trading the subsequent price breakout. It is designed to be a complete, "set-and-go" system with built-in risk and position size management.
The core logic operates on the 1-Hour timeframe, scanning for four distinct high-probability reversal signals: two bullish and two bearish. An entry is only triggered when the market confirms the signal by breaking a key price level, aiming to capture momentum following a potential shift in market sentiment.
The Strategy Logic
The system is composed of two distinct modules: Bullish (Long) and Bearish (Short).
🐂 Bullish (Long) Setup
The script initiates a long trade based on the following strict criteria:
Signal: Identifies either a Hammer or a Bullish Engulfing pattern. These patterns often indicate that sellers are losing control and buyers are stepping in.
Confirmation: Waits for the very next candle after the signal.
Entry Trigger: A long position is automatically opened as soon as the price breaks above the high of the signal candle.
Stop Loss: Immediately set just below the low of the signal candle.
Take Profit: A fixed target is placed at a 1:5 Risk/Reward Ratio.
🐻 Bearish (Short) Setup
The script initiates a short trade based on the following strict criteria:
Signal: Identifies either a Shooting Star or a Bearish Engulfing pattern. These patterns suggest buying pressure is fading and sellers are taking over.
Confirmation: Waits for the very next candle after the signal.
Entry Trigger: A short position is automatically opened as soon as the price breaks below the low of the signal candle.
Stop Loss: Immediately set just above the high of the signal candle.
Take Profit: A fixed target is placed at a 1:4 Risk/Reward Ratio.
Key Feature: Automated Risk Management
This strategy is designed for disciplined trading. You do not need to calculate position sizes manually.
Fixed Risk: The script automatically calculates the correct position size to risk exactly 2% of your total account equity on every single trade.
Dynamic Sizing: The position size will adjust based on the distance between your entry price and your stop loss for each specific setup, ensuring a consistent risk profile.
How To Use
Apply the script to your chosen chart (e.g., BTC/USD).
Crucially, set your chart's timeframe to 1-Hour (H1). The strategy is specifically calibrated for this interval.
