To save your custom Fibonacci levels and colors in StocksTrader, you can follow these steps: 

1. After adjusting your Fibonacci retracement levels and colors, open the side menu on the left (by clicking on the small arrow near the company's logo).

2. Find the drop-down menu, click on it and select "New layout". You can rename the layout as you wish. 

3. Set up your chart to your preferences – add indicators, adjust colors and appearance. 

4. This new layout with your settings will be available in the menu and you can switch to it when needed. Automatic settings for all new charts are not available, but this way you can quickly select the chart with your favorite settings.
