Using meditation in trading refers to approaching the activity with a sense of equanimity and non-attachment, similar to the principles of Buddhism. This can involve accepting that losses are a natural part of the process and not becoming overly attached to the outcome of a trade. It also means to be mindful of the present moment and not getting caught up in future projections or past regrets. It can also mean being honest with oneself, being open to learning, and having a sense of compassion for others. By implementing these principles, a trader may be less prone to making impulsive decisions based on emotions and more likely to make rational and well thought-out trades.
