How to Read the Options Chain on Pluang
The options chain on Pluang is the list of call and put contracts available for an underlying asset: you choose the underlying, pick Call or Put, and then see the contracts sorted by expiry date and strike price. Reading it correctly tells you three things at a glance: the cost to open a position — the premium, shown as the middle price between the bid and ask executed in the market and refreshed every 5 seconds — whether a strike is in-the-money, at-the-money, or out-of-the-money relative to the underlying, and how sensitive that specific contract is to price, time, and volatility changes through risk measures such as the Greeks (delta, gamma, theta, vega) shown on the contract page. Liquidity signals such as the order book and the "Low Liquidity" label show how easy a contract is to trade; thin liquidity typically means wider bid-ask spreads and a harder exit before expiry. Checking these five elements together — expiry/strike, moneyness, price, Greeks, and liquidity — before entering any position is standard practice on Pluang's options chain.
- Expiry and strike layout. After you choose an underlying and pick Call or Put, the contracts are listed sorted by expiry date and strike price. Available strike intervals and expiry dates vary by underlying — check the list itself for the specific contracts Pluang currently offers on a given stock.
- Reading moneyness from the chain. Strikes below the current underlying price are in-the-money (ITM) for calls and out-of-the-money (OTM) for puts; strikes above the current price are OTM for calls and ITM for puts. ITM contracts carry intrinsic value on top of time value, which is why they trade at a higher premium than OTM contracts at the same expiry.
- Price, bid, and ask. The price shown for each contract is the middle price between the bid and ask executed in the market, refreshed every 5 seconds. The bid is the highest price a buyer is currently willing to pay; the ask is the lowest price a seller is currently willing to accept, and the order book shows the bid and ask volume at each price level. The gap between the two — the bid-ask spread — is the transaction cost you absorb by crossing the market with a market order.
- Greeks on the contract page. The contract page shows risk measures such as the Greeks: delta (how much the option's price moves per $1 move in the underlying), theta (the premium lost to time decay each day), vega (sensitivity to changes in implied volatility), and gamma (how fast delta itself changes). Comparing these across strikes tells you which contract reacts most aggressively to a move in the underlying versus which one is mainly bleeding value to time.
- Liquidity signals. The order book shows the bid and ask volume at each price level, and a "Low Liquidity" label flags thinly traded contracts; contracts too illiquid to trade without significant price slippage are left out of the list entirely. Open interest (OI) — the total number of contracts at that strike and expiry that remain open, not yet closed or settled — and session volume are other common liquidity measures: higher readings generally mean tighter bid-ask spreads and easier entry/exit. A contract with very low liquidity can be difficult to exit at a fair price before expiry, even if the underlying moves in your favor.

Q: What does zero open interest mean for an options contract?
Zero open interest means no contracts at that specific strike and expiry are currently held open by any trader — none have been bought or sold and left outstanding. Entering a brand-new position at that strike can mean a wider bid-ask spread than a more actively traded strike nearby, since there is no existing pool of counterparties. It does not mean the contract cannot be traded; it just signals thinner liquidity, so consider comparing volume and spread on adjacent strikes before placing an order.
Q: How do I narrow the options chain on Pluang to only near-the-money strikes?
Because contracts are listed sorted by expiry date and strike price, the strikes closest to the current underlying price — the near-the-money ones, where liquidity usually concentrates — sit next to each other in the list for each expiry, so you can scroll straight to them. Any extra filter or view controls can vary by app version, so check the contract list screen directly rather than assuming a fixed menu path.
Q: Why does the same option contract show a different price at different times of day?
The price Pluang shows for each contract refreshes every 5 seconds through the trading session, and it moves as the underlying's price moves, implied volatility shifts, time to expiry ticks down, and buy/sell order flow changes the bid and ask. Even with the underlying unchanged, a contract's premium can drift slightly as theta decays it minute by minute, which is most visible on contracts close to expiry. Refreshing the options chain shows you the latest quote rather than the one loaded when you opened the screen.
Q: Besides delta, gamma, theta, and vega, does Pluang's chain show other Greeks like rho?
Rho, which measures sensitivity to interest rate changes, is another Greek used in options theory, but it matters far less for the shorter-dated contracts most retail traders hold. Delta, gamma, theta, and vega cover price, time, and volatility risk, which are the drivers that move an option's premium day to day. Open a contract in the app to see which risk measures it shows.
