Ways to backtest your trading strategy

Once you have developed a potential strategy that you believe to be the real deal, it is time to test it out. There are several ways to backtesting trading strategies. They are mainly divided into two methods; manual and automated backtesting.

·         Manual backtesting

Manually backtesting a trading strategy, however, you view it, is pretty exhausting. However, this method provides traders, especially beginners with a real feel of how the market works. If you are looking for some practical experience in trading, manual backtesting is the way to go.

Follow these steps to backtest your trading strategy manually:

o   Step 1

Obtain a trading chart that is easy to read and feed in the desired currency pair you wish to backtest on. If you have any indicators or tools that make up your strategy, include them on the chart. Roll the chart back several periods.

o   Step 2

Shift the chart bar after bar and seek out possible trading setups. This is the grueling part, as you will have to sift through hundreds of them at a time to find the perfect setup.

o   Step 3

Once you spot a possibly profitable setup, log all the information as pertains to your ‘virtual’ trade. An Excel spreadsheet is the best way to record the data. Note down starting date, entry point, reward-risk ratio, stop-loss, take-profit plus any other information you deem noteworthy. This will be used to analyze the strategy and gauge the success or failure of the same.

o   Step 4

Step 4 isn’t necessary if you have found a working strategy. If not, however, get back on the chart and sift, once more, through the bars as you fine-tune your approach until you find a worthy setup. Then you can proceed to Step 3.

Manual backtesting is, from the onset, time-consuming. This is especially true since you will have to sift through piles of data unaided by any computer. Moreover, any proper backtest needs to go through as much data as possible.

Ten years’ worth of trading information is the go-to standard if you are looking to day trade your strategy. If you decide to go through such data, you ought to be mentally prepared for the workload. However, it is the most definitive way traders get to learn actual trading.

It is fast and traders can then evaluate a trading strategy faster than it would have taken using the manual method. Moreover, traders might have several approaches on tap and backtesting all of them manually just wouldn’t cut it.

Usually, to conduct an automated backtest, you first have to get a backtesting software. First, there are free versions that we shall consider in this article. Paid versions are also available and even demo accounts count as backtesting software.
