The first tarot, the Knight of Wands, represents an optimistic view of the question. The Knight is a sign of action and progress, indicating that the answer to the question will be positive. Also, Wands are associated with vital energy and a willingness to do something productive. This suggests that there is a good chance of a big profit through long-term trading activity.

The second tarot, Ten of Cups, can also represent a negative view of the question. Cups are associated with emotions and relationships, so the Ten of Cups can indicate that investing is not only based on financial analysis but also on emotional factors. This could mean that the final result will not necessarily be positive and that these more subtle aspects must also be considered.

The third tarot, Six of Pentacles, shows one possible outcome of the question. Six indicates stability and security, while Pentacles are associated with money. So this card can be interpreted as a good long-term financial return through stock trading.

The last card, the reversed Eight of Cups, shows advice for dealing with the question. The Eight represents the balance between opposing forces, while the Cups indicate that one must be aware of one's emotions when making important financial decisions. So this card reminds us of the importance of maintaining the balance between logic and feeling when investing in stocks for the long term.

In summary, tarot cards give a probably positive answer to the question of what are the chances of a big profit from long-term stock trading. However, the tarot also invites us to consider the emotional aspects and to act in a balanced way to achieve maximum financial success. Yes, so the answer to the question is probably yes.
