Yes. 3SIL and similar instruments are only suited to intra-day trading. They are not intended to track accurately over periods longer than one day, because of a characteristic known as daily reset which creates an undesirable effect referred to as leverage drift.
If the relevant index rises by (say) 15% over the course of a week, you should not expect a return of 45% on your 3x leveraged etf. If you don’t understand why this, you are swimming naked and out of your depth...
