Time-based trading strategies capitalize on the recurring patterns seen at specific times in the financial markets. By focusing on particular trading sessions, like the London or New York sessions, traders can take advantage of periods of heightened volatility and liquidity. TradeStation’s EasyLanguage makes it straightforward to build, test, and automate time-based strategies, giving traders a solid foundation to execute strategies consistently across different market sessions.

In this guide, we’ll walk through creating a time-based strategy using EasyLanguage, discuss the performance differences between the London and New York sessions, and provide code examples to help you get started. By backtesting across sessions, traders can identify the optimal timeframe for strategy deployment.

Why Use a Time-Based Strategy?

The forex and futures markets exhibit unique behaviors depending on the time of day, with the London and New York sessions accounting for the bulk of trading activity and volatility. The London session, starting around 8:00 AM GMT, is known for strong price moves as European markets open. The New York session, beginning at 8:00 AM EST, often brings high volatility, especially when overlapping with the London session, creating opportunities for more substantial price movements.

A time-based strategy capitalizes on these session-based patterns, allowing traders to focus on the hours when the market is most active. By defining specific entry and exit times in an automated strategy, traders can participate only during these high-activity periods, which is particularly useful for those who wish to avoid market inactivity or reduce overnight exposure.

Building a Time-Based Strategy with EasyLanguage

Creating a time-based strategy on TradeStation involves the following steps:

1. Identify Entry and Exit Times: Define the session window for trade entries and exits. For instance, set the strategy to open positions only during the London session, with a hard stop or exit at the end of the session.

2. Set Entry and Exit Rules: Establish the conditions for entering or exiting trades, such as buying or selling based on specific price action within the session window.

3. Include Risk Management: Define stop-loss, take-profit, or trailing stops to manage risk effectively.

4. Backtest and Optimize: Run the strategy over historical data for both the London and New York sessions to assess which timing delivers the best performance.

Code Example in EasyLanguage for a Time-Based Strategy

Below is an example of a time-based strategy in EasyLanguage. It allows trades only within a specified timeframe and exits any open positions at the session’s end.

// Time-Based Trading Strategy

Inputs: StartTime(0800), EndTime(1200), StopLossAmt(1000), TargetAmt(2000);
Vars: tradeEntryPrice(0), sessionActive(false);

// Check if within the trading session time window
If Time >= StartTime and Time < EndTime then sessionActive = true
Else sessionActive = false;

// Buy Condition - Buy only if within session time
If sessionActive and Close crosses above High[1] then
Begin
    Buy("Entry") next bar at market;
    tradeEntryPrice = Close;
End;

// Exit at session end or if stop-loss/target is hit
If Time >= EndTime and MarketPosition = 1 then
    Sell("ExitEndSession") next bar at market;
Else
    Begin
        If (MarketPosition = 1) and (tradeEntryPrice - Close >= StopLossAmt) then
            Sell("StopLoss") next bar at market;
        
        If (MarketPosition = 1) and (Close - tradeEntryPrice >= TargetAmt) then
            Sell("Target") next bar at market;
    End;

Code Breakdown

1. Input Parameters: Define the trading session window (e.g., 8:00 AM to 12:00 PM) using StartTime and EndTime, as well as stop-loss and target amounts.

2. Session Timing: sessionActive checks if the current time is within the specified session window, allowing trades to be executed only during that period.

3. Entry Condition: A buy order is placed if a breakout occurs within the active session window, using Close crosses above High[1] to trigger entry.

4. Exit Conditions: Positions are closed either at the session’s end or based on stop-loss or profit target thresholds, effectively managing risk and session boundaries.

Backtesting the London vs. New York Sessions

Backtesting is essential for determining which trading session offers the best results for your strategy. TradeStation provides robust backtesting features that allow traders to test different timeframes, optimize input parameters, and view performance metrics, such as profit factor, win rate, and drawdown.

Session-Based Differences

1. London Session: Known for its high volatility, the London session is typically more active at market open and during the overlap with the New York session. Traders focusing on breakout or momentum-based strategies may see improved results during this time due to the strong price moves.

2. New York Session: With significant volatility due to the overlap with the London session, the New York session also offers high liquidity. For those focused on U.S. equities or dollar pairs, the New York session can be ideal, especially around the U.S. economic announcements.

By running the time-based strategy over both sessions, you can identify which provides higher returns, lower drawdowns, or a higher win rate, allowing for optimization. EasyLanguage on TradeStation also provides detailed session reports, giving insight into performance across various conditions.

Benefits and Limitations of Time-Based Strategies

Benefits:

• Improved Efficiency: By focusing on active market hours, time-based strategies can yield better results by avoiding low-liquidity periods.

• Reduced Overnight Risk: With exits at the end of each session, time-based strategies limit exposure to overnight events.

• Consistent Execution: Automated time-based strategies ensure trades are executed without delay during peak hours.

Limitations:

• Time Dependency: Results may vary based on session conditions, making adaptability key.

• Technical Challenges: Automated time-based strategies require consistent platform uptime and reliable internet, which is crucial when trading volatile sessions.

• Limited Flexibility: Relying solely on specific times may mean missed opportunities outside those windows.
