Backtesting lets a trader know whether a strategy has profit potential, while forward testing helps to confirm or refute this. Forward testing (also known as walk forward optimisation) is also slower because it needs to be performed in real time. Each day is traded as it comes, whereas with backtesting, a trader can arrange years’ worth of historical trades in a single day, if desired. Backtest indicators can include the levels or signals that will trigger an entry or exit for a trade. Typically, this is an objective time, like a close or open following the signal, which helps avoid any confusion as to when the trade should be taken.

The simplest backtest includes looking at one-minute or five-minute chart timeframes, for example, of the asset being traded. You could find prior trades based on that strategy and then add up the profits and losses, which would provide an idea of the profit produced that week. The percentage return should give an indication of how successful the strategy is.

This is a rudimentary template you can use as a starting point to creating your own. It gives you a general idea of what information a backtesting sheet may contain. Some traders prefer to use Excel or code it in Python; there aren’t strict rules.

Backtesting vs. Forward Performance Testing

It indicates how much the portfolio is expected to increase or decrease when the market moves by a certain percentage. A beta less than 1 implies the portfolio moves less than the market, while a beta greater than 1 means the portfolio moves more than the market. A beta of 1 indicates the portfolio has the same volatility as the market. But the strategy includes a diversified set of stocks that belong to different sectors. This is because if you only keep stocks from a particular sector, say technology. Then in scenarios like the Dot-com bubble, your strategy will be doomed.

It helps to avoid overfitting to past data and provides a more reliable assessment of how the strategy may perform in the future. By contrast, scenario analysis tests a strategy against a set of hypothetical market conditions, perhaps not found in historical datasets. We’ve gone through the basic process of how to perform a manual backtest of a trading strategy. However, it’s important to remember that past performance doesn’t guarantee future performance. Do bear in mind that these aforementioned examples do not constitute an exhaustive list. In any case, the more details you include in your trading journal about relevant set-ups, the more opportunities you’ll have to learn from the results.

Traders often fine-tune the strategy’s parameters during backtesting to achieve the best possible results for the selected historical period. Walk forward testing divides the historical data into multiple segments, such as in-sample (training) and out-of-sample (testing) periods. It allows traders and investors to simulate trades and analyse how the strategy would have performed in the past. By annualising the returns, investors can better compare the performance of different investment strategies on a consistent basis and assess their long-term profitability. Cumulative returns, also known as absolute returns, measure the total gain or loss of an investment over a specific period, regardless of the time taken. Once the necessary adjustments have been made, validate the strategy by conducting additional tests on different data sets or time periods to ensure its robustness and consistency.

Backtesting and forward testing can be used together to give a more complete picture of how a strategy performs, both historically and in real time. It provides a look into the past performance of a strategy and helps identify strengths, weaknesses, and areas for improvement. Walk forward testing is an advanced method that combines elements of backtesting and out-of-sample testing. It aims to address the limitations of backtesting by incorporating ongoing optimisation and validation steps.

Better Risk management

Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 67% of retail investor accounts lose money when spread betting and/or trading CFDs with this provider.

At minimum, a trading strategy helps to define entry and exit points for both winning and losing trades, plus a position size. In addition, a trading strategy will often provide context, such as defining if and when trades should be taken. For example, only when the price is above or below a moving average, or during the first hour of the day.

As always, there are no guarantees and as such, you should still consider risk management tools. Keep track of the trades executed during the backtesting process, including entry and exit points, trade duration, profit or loss, and other relevant metrics. While backtesting provides historical performance insights, walk forward testing offers a more dynamic and forward-looking assessment of a trading strategy’s potential. Walk forward testing helps to reduce the risk of overfitting, provides a more realistic evaluation of a strategy’s adaptability, and offers greater confidence in its future performance. While backtesting provides valuable insights, it does not guarantee future performance. Backtesting instils confidence in traders before engaging in live trading.
