Developing Automated Trading Strategies

Algorithm Development with thinkScript

To illustrate the process of developing an algorithmic trading strategy, let’s explore a basic moving average crossover strategy using thinkScript.

input shortLength = 9;
input longLength = 21;

def shortMA = Average(close, shortLength);
def longMA = Average(close, longLength);
def crossover = shortMA crosses above longMA;

plot BuySignal = if crossover then low else Double.NaN;
BuySignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);

plot SellSignal = if crossover crosses below longMA then high else Double.NaN;
SellSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

Backtesting Strategies

Once you develop your algo strategies, testing them is crucial for ensuring their effectiveness.

• Use the Thinkorswim Backtesting Feature: The platform provides a user-friendly interface for backtesting scripts, allowing you to see how a strategy would have performed based on historical data.

Applying the Trailing Stop Strategy

Trailing stop strategies can be pivotal in locking in profits and minimizing losses. Here is a simple approach to implementing a trailing stop in your algo trading.

1. Define Your Parameters: Decide how far you want your trailing stop to follow the market price.
2. Implement in thinkScript: You can embed trailing stop criteria in your thinkScript to automate adjustments based on the asset’s price movements.

input trailOffset = 1.00; // Trailing stop offset in dollars

def highestHigh = Highest(high, 20); // Look back over the last 20 bars

plot TrailingStop = highestHigh - trailOffset; // Set trailing stop level

Thinking Strategically About Automated Trading

Developing Effective Trading Strategies

To have success in algorithmic trading, you need to craft strategies that account for various market dynamics. Here are a few foundational strategies you might consider:

Trend Following

• Description: Leverages momentum by executing buy orders when the market trends upward, and sells when the trends reverse.
• Implementation: Use Simple Moving Averages (SMA) or Exponential Moving Averages (EMA) to identify entry and exit points.

Statistical Analysis and Data Collection

Collecting and analyzing market data is integral to formulating a robust trading strategy.

• Historical Data Analysis: Review past price movements and patterns to predict future behaviors.
• Using Statistical Tools: Tools such as R or Python can handle complex statistical models that can benefit your algo trading initiatives.

Case Study: Backtesting a Trend Following Strategy

To provide a real-world example, consider a trend-following strategy backtested over a 5-year period. Assume a strategy using a 50-day SMA shows:

• Win Rate: 65%
• Average Profit per Trade: $150
• Number of Trades Executed: 100

Collectively, that would present a robust opportunity for profit.

Trading Psychology in Automated Transactions

Understanding the Human Element in Algo Trading

Even with the advantages of automated trading, psychology plays a role. Understanding how psychological biases can impact decision-making is crucial for developing resilient trading strategies.

Avoiding Common Trading Pitfalls

• Over-Trading: Automated systems can lead to excessive trading if not set correctly.
• Ignoring Market Conditions: Algorithms must be adjusted according to changing market trends and volatility.
