Looking at the first card, The Sun, we have an image of strength and vitality. His energy is that of a being who knows how to manage his physical energies and knows how to focus on a particular goal. This seems to indicate that you have the resources to achieve your financial goal for short-term gain.
The second card, The Devil reversed, shows us a person who is dealing with his emotions. It could be that you are aware of your fears and insecurities in relation to finances. However, the card also suggests that you are trying to overcome these fears and make more sensible decisions about your short-term trading activity.
The last card, Two of Cups reversed, shows a person who must learn to let go of his fears and insecurities and be more confident in facing life. This seems to suggest that if you are willing to face your fears and be mindful of your spiritual state, then you stand a better chance of achieving short-term financial success.
In conclusion, from the three cards drawn it can be said that you have a good chance of making a significant profit through short-term trading activity. However, you will need to be able to overcome your fears and insecurities and be more aware of your spiritual state in order to have a better chance of financial success. So, the answer to the question is "Yes".
