Range Breakout System is a trading strategy that identifies and trades price breakouts from a predefined range. Traders use this system to capture momentum when an asset moves beyond a support or resistance level.
Concept
The strategy is based on the assumption that when the price breaks above or below a well-defined range, it is likely to continue moving in that direction. The range is typically defined by:
- High and low prices over a period – Example: The highest and lowest prices over the past 20 days.
- Support and resistance levels – Key levels where price repeatedly reverses.
- Opening range – The high and low of the first trading hour.
Trading Rules
- Identify the range: Define the breakout levels based on past price action.
- Buy Signal: When the price breaks above the range.
- Sell Signal: When the price breaks below the range.
- Stop-Loss: Placed slightly below (for long trades) or above (for short trades) the breakout level.
- Take Profit: Set using risk-reward ratios or trailing stops.
Example
A simple implementation of a range breakout system using Python:
import pandas as pd
import matplotlib.pyplot as plt
# Load historical stock data
df = pd.read_csv("stock_prices.csv")
# Define the range (e.g., last 20 days high and low)
df["High_20"] = df["High"].rolling(window=20).max()
df["Low_20"] = df["Low"].rolling(window=20).min()
# Generate buy and sell signals
df["Buy_Signal"] = df["Close"] > df["High_20"]
df["Sell_Signal"] = df["Close"] < df["Low_20"]
# Plot the data
plt.plot(df["Close"], label="Stock Price")
plt.plot(df["High_20"], label="20-Day High", linestyle="dashed")
plt.plot(df["Low_20"], label="20-Day Low", linestyle="dashed")
plt.legend()
plt.show()
