Using the Web App
The Tradewell web app is made up of a backtesting engine, data sets, and various analytics tools. When you join Tradewell, you’ll set the amount of data you can access in your web app when you choose your membership plan. Here's how to open your web app to analyze trading strategies.
The asset field is where you pick the security you'd like to backtest. You can enter the full ticker symbol of the security directly, or you can search for it in the field itself. Currently Tradewell supports equities, ETFs, commodities, crypto currencies and forex. Just start typing the name or first few letter of the security in mind, and a dropdown many will appear with a list of likely securities. Click the name of security you want to backtest, and it symbol will automatically load in the asset field.
Once you've selected your security, use the Update button to load it on the chart. The button will also reset the range of filtered values for metric that appears on the chart, in the event that the metric is universal across tickers. If the metric is not universal across tickers, ie. the metric is a proprietary metric or limited to a specific asset class, the metric values will remain the same.
The metric selection field is composed of three dropdown menus stacked on top of each other. The field allows you to change the metric on the chart. The top menu contains the major categories of metrics available on the platform. The middle menu contains contains a sub-category of metrics within the first category. And the bottom menu contains the individual metrics that you can load on the chart. By default, the app shows the top category as "Technical", the subcategory as momentum, and then the metric itself as a 14-period RSI. The entire metric catalog can be found here.
The filter section allows you to define the rules of your trading strategy before you convert those rules into signals. The section is composed of a range slider with two green handles that define a lower and an upper bound of a metric, as well as two input boxes where you can directly enter these values if you prefer. By default, the range slider and input boxes are pre-populated with values equivalent to the minimum and maximum bounds of the metric on the chart itself — so you are automatically prevented from filtering values of the metric that do not exist.
Once you've used the filter section to select a range of metric values to backtest, hit the "DISPLAY SIGNALS" button so that your signals appear on chart. You can identify them as the black circles that appear on price and metric line charts, and as black markers on the candlestick and OHLC charts.
The RUN BACKTEST button is the last button to press once you have followed the above steps. Pressing this button will backtest the forward returns of the asset you've selected, whenever one of the signals you have created fires. The default forward return period shown in the Scatterplot and the Distribution of Returns is 20 days. The Historical Forecast tab shows the price path the asset took over the next 60 days. And the Summary Table and Signal Data display, respectively, n-period return and a statistical summary snapshots over 1 to 60 trading days.
The lookback period range slider can be found at the bottom of the chart. You can use the range slider to select more data — up to 50 years of price data if using the "Pro" version of the app. You can also use the range to filter between different dates. For example if you want to adjust the lookback period to the timeframe between 10 and 15 years ago, you would simply move both of the green handles: the left handle to 10 years and the right handle to 15 years. Then press the Adjust button.
