Market maker
Un operatore che quota continuamente prezzi bid e ask, fornendo la liquidità che ti permette di negoziare opzioni in qualsiasi momento.
A market maker is a firm (or trading desk) that continuously quotes both a bid and an ask on an option, standing ready to buy from you or sell to you at any moment. Without them, most option strikes would have no one on the other side of your order, so they are the reason you can click buy or sell and get filled almost instantly. They earn the spread between those two prices and hedge the risk they take on, usually in the underlying stock.
In practice this matters most when you look at liquidity. A tight bid-ask spread, say 1.20 by 1.22, tells you a market maker is actively competing and you can enter and exit cheaply. A wide spread like 1.10 by 1.60 warns you the strike is thinly traded and every round trip will cost you.
A common mistake is placing market orders on illiquid options. You are effectively letting the market maker pick the price, and you may pay far above the true mid. Use limit orders near the mid and let the quote come to you instead.
