It is currently not possible to add specific timeframes to your favorites. However, you can select and customize the default timeframes in the StocksTrader web terminal. To add custom timeframes, follow these steps: 

1. Select the timeframe button. 

2. Scroll down to set up your custom timeframe. 

3. Select the desired value—in this case, 5 minutes and 1 hour. 

4. Save your custom timeframe by pressing the "OK" button. 

These custom timeframes will then appear under the default options.
