We all have emotions, so, I learn that when I buy at left side, I buy normal stocks (buying yesterday is left side). This way, I have the confidence to hold even if I am wrong
But when I buy 2x or 3x leverage, I usually buy at right side with proper stop loss. This is counter-intutitive because buying at right side means stock already shorts higher at that time. However, emotionally, it gives me better chance to hold it.
It took me many many years to get used to this trading principal.
