What Is the Minimum Purchase for an Options Contract on Pluang?

The minimum purchase for an options contract on Pluang is 1 contract, and every contract represents 100 shares of the underlying stock or ETF. Because of this 100-share multiplier, the actual cost of buying 1 contract is the quoted premium (the per-share option price) multiplied by 100 — not the premium figure shown on its own. For example, if an option is quoted at a premium of $2.00 per share, buying the minimum 1 contract costs $200 ($2.00 × 100), plus any applicable fees. Pluang does not support fractional contract purchases: you cannot buy half a contract or a partial lot, unlike fractional share purchases on US Stocks. This 100-share multiplier and 1-contract minimum apply identically whether you are buying a call, buying a put, or writing (selling) a contract, and whether the underlying is a US Stock Option or a US ETF Option.

• Contract multiplier: 1 options contract = 100 shares of the underlying asset. This is a fixed industry-standard multiplier, not a Pluang-specific setting.
• Total cost formula: Premium per share × 100 × number of contracts = total premium paid (for a buy order) or received (for a sell/write order), before fees.
• No fractional contracts: Orders must be placed in whole-contract increments starting at 1 — there is no way to buy or sell a partial contract on Pluang.
• Applies across contract types: The 100-share multiplier and 1-contract minimum are the same for calls, puts, US Stock Options, and US ETF Options, since both trade under the same PT PG Berjangka license.
• Access requirement: Placing any options order — including the minimum 1-contract purchase — requires completing Global & Yield Asset Verification first, since Options is only unlocked at that KYC tier.

Q: How do I calculate the total cost of buying 1 options contract?
Multiply the quoted premium (price per share) by 100, since 1 contract always represents 100 shares of the underlying stock or ETF. For example, a premium of $1.50 means a total cost of $150 for 1 contract, before any fees are added. This calculation applies the same way whether the underlying asset is a US Stock or a US ETF Option, and whether you're opening a long call, long put, or writing a contract.

Q: Can I buy less than 1 full options contract on Pluang?
No, Pluang does not support fractional options contracts — every order must be placed in whole-contract increments, with 1 contract as the minimum. This is different from US Stocks, where Pluang allows fractional share purchases. If your available balance can't cover the cost of 1 full contract (premium × 100), you won't be able to place the order until you top up.

Q: Does the 100-share-per-contract rule apply to both calls and puts?
Yes, the multiplier is identical for calls and puts — every options contract on Pluang, regardless of type or direction (buying or writing), represents exactly 100 shares of the underlying stock or ETF. The only variable that changes your total cost is the quoted premium itself, which moves with the option's strike price, expiry, and market conditions, not the multiplier. So a quoted premium of $2.00 always means $200 per contract, whichever type you trade.

Q: Is the contract size different for US ETF Options compared to US Stock Options?
No, US ETF Options use the same 1-contract minimum and 100-share multiplier as US Stock Options, since both products are offered under the same PT PG Berjangka license and regulatory framework. Whether the underlying is an individual stock or an ETF, 1 contract always equals 100 shares, and the total premium is calculated the same way for both. This keeps position sizing consistent whether you trade stock or ETF contracts.
