Can you get assigned on a long option (one you bought)? No. Assignment only happens to option sellers, not buyers. If you bought (are long) a call or put, you can never be assigned — you hold the right, not the obligation. Here's why that's a clean, absolute rule.
Rights vs. obligations
When you buy an option, you own a right: the right to exercise if you choose. You're in control — nothing can be forced on you. When you sell (write) an option, you take on an obligation: if the buyer exercises, you can be assigned — forced to deliver. Assignment is the seller's risk, the mirror of the buyer's right. Since a long position is a right, not an obligation, there's nothing to assign to you.
What this means for you
Because NoVo trades long options (you're buying calls and puts), assignment risk simply doesn't apply to your positions. The only expiration mechanic you face is auto-exercise if you hold an ITM option to the bell — which you control by simply selling before expiration. There's no counterparty who can force anything on your long option mid-trade.
Buyers hold rights; sellers hold obligations. Assignment is a seller's problem — if you bought the option, it's simply not on your list of things to worry about.
The quick takeaway
Long options can't be assigned — assignment is only for sellers. As an option buyer, your risks are the premium and (if you hold ITM to expiration) exercise, both of which you control. This is one reason buying defined-risk long options is beginner-friendlier than selling. See how NoVo handles assignment and assignment & exercise explained.
