Depending on your account and status there are many disclaimers and additional contract parts you may have to acknowledge or sign when trading certain products. If you do not understand these legal documents (after reading them, not after consulting internet strangers), you should not trade the product.
At Swissquote, the NACH disclaimer I know basically says “This is no offer but only information. This information is only for qualified investors. We are not liable if you lose your investment.” You should at least check what you are agreeing to. Are you just acknowledging it? Are you giving Swissquote a liability waiver? Worst case: Are you unintentionally declaring yourself a qualified / institutional investor*?
Of course in reality nothing much happens. If you see such a note, they are obviously going to let you trade as all they want is your absolve from any liability.
*If you have > CHF 500k in invested/investable assets you are in most cases deemed a qualified investor (independent of your actual knowledge).
