Share a quote from 'Gary (author of Stock Depth Trading Psychology)':

【If the entry model itself is already satisfactory, adding extra information will not affect the trading results, but it will influence our feelings about the trade, possibly filling us with confidence. Perhaps this seems beneficial, but in reality, it is merely a blind and hollow confidence, as adding extra information does not improve accuracy. Worse still, we may feel overly confident and take on too large a position because much information points towards a certain predictive direction.

Here, we also mistakenly use technical information to adjust our feelings and boost our confidence. In this process, we may become overly bold, not acting according to the objective probabilities of the entry model, but rather acting based on the feelings generated by this trade.】

Recently revisiting trading psychology, I was deeply touched to see this quote again. I tend to unconsciously integrate multiple theories or pursue so-called multi-indicator resonance, but this does not necessarily prove a higher success rate in trading; it merely boosts confidence and still cannot change the outcome of losses. Moreover, when integrating various technical theories, different analytical results can lead to decision-making confusion. Finding the one that best suits me is enough.
