What Is Exercise in Options Trading on Pluang?

Exercise in options trading is the action a buyer (long holder) takes to use their contractual right to buy the underlying asset at the strike price for a call, or sell it at the strike price for a put. On Pluang, US Stock Options and US ETF Options are American-style contracts, so you can exercise this right at any point before the contract's expiry date, not only on expiry day itself. Only the buyer of an option holds this right; sellers (short positions) cannot exercise — instead, they may be assigned when a buyer on the other side of their contract chooses to exercise. Because Pluang's options are American-style, early assignment risk is real for anyone holding a short call or put, and can occur well before the stated expiry date. Exercise decisions must be made before Pluang's expiry-day cutoff, since the platform automatically force-closes any open options position roughly one hour before market close on expiry day.

How exercise plays out mechanically:

• Exercising a call means buying the underlying shares or ETF units at the strike price, regardless of where the market is currently trading.
• Exercising a put means selling the underlying at the strike price.
• Exercise only comes from the long (buyer) side of a contract; the matched short position on the other side is the one that gets assigned as a result.
• Trading options on Pluang requires completing Global & Yield Asset Verification first.
• Options are custodied through Atomic Vaults LLC, with SIPC account protection.
• Any confirmed exercise-related cost is shown in the app before you confirm the action — check current terms there rather than assuming a fixed figure.

Q: What's the difference between exercising an option and being assigned?
Exercising is an action only the option buyer (long holder) can take — choosing to use their right to buy or sell the underlying at the strike price. Assignment is what happens on the other side: when a buyer exercises, one of the sellers (short position holders) of that same contract type, strike, and expiry is matched with the resulting obligation. In short, buyers exercise by choice; sellers get assigned as a result of someone else's exercise decision, which they cannot refuse or opt out of once matched.

Q: Can I exercise a Pluang option before its expiry date?
Yes. Pluang's US Stock Options and US ETF Options are American-style, so you can exercise a long call or put at any point before the contract's stated expiry date — you don't have to wait until expiry day. This is different from European-style contracts, which only allow exercise at expiry. Because exercise can happen early on Pluang, anyone holding a short position should treat early assignment as a real, ongoing risk rather than something that only matters on the last trading day.

Q: What happens if I hold an option through expiry day without exercising it?
You don't need to manually exercise on expiry day itself — Pluang automatically force-closes any options position that is still open, roughly one hour before market close on the expiry date. This means the platform steps in ahead of expiry rather than leaving your contract to run to a passive, automatic cash-settlement with no prior action on your part. To control the outcome yourself — for example, to actually take delivery of the underlying via exercise — you need to submit your exercise instruction before this cutoff.

Q: Who has the right to exercise an option — the buyer or the seller?
Only the option buyer (the long holder of a call or put) has the right to exercise. The seller (short holder) has an obligation, not a right — they must fulfil the trade at the strike price if a buyer matched to their contract chooses to exercise, and they only find out once they're assigned. This asymmetry is central to options trading: buyers pay a premium for the right to choose, while sellers collect that premium in exchange for the obligation to perform if exercised.
