What is option chain ?

OPTION CHAIN.

 An option chain is a table that displays all available options contracts for a particular underlying asset (such as a stock, ETF, or index), for a given expiration date. It helps traders and investors analyze and choose which options to buy or sell.

Key Components of an Option Chain:

  1. Calls and Puts:

    • Call Options: The right to buy the underlying asset at a specific price.

    • Put Options: The right to sell the underlying asset at a specific price.

  2. Strike Price:
    The price at which the underlying asset can be bought (call) or sold (put).

  3. Expiration Date:
    The date the option contract expires. After this date, the option becomes worthless if not exercised.

  4. Last Price:
    The most recent trade price of the option.

  5. Bid and Ask:

    • Bid: The highest price a buyer is willing to pay.

    • Ask: The lowest price a seller is asking.

    • The difference is called the spread.

  6. Open Interest:
    The total number of outstanding (not yet closed or exercised) contracts.

  7. Volume:
    The number of contracts traded during the current session.

  8. Implied Volatility (IV):
    The market's forecast of how much the underlying asset is expected to move.

Example Layout of an Option Chain:

CallsStrike PricePuts
BidAskLastLastAskBid
2.002.102.05100.001.951.901.85

Each row shows options for a specific strike price, with data for both calls and puts.

Why It's Useful:

  • Helps analyze potential trades

  • Compare premiums across strikes and expirations

  • Assess liquidity and market sentiment

  • Find the best strike price for your strategy

Emotional control: Stay calm through wins and losses. Patience: Wait for high-quality setups. Confidence: Comes from practice, backtesting, and journaling. 💡 Tip: Journaling your trades and emotions helps spot self-sabotaging patterns. 📊 2. Risk Management "It's not about how much you make—it’s about how much you keep." Position sizing: Risk a fixed % of your capital per trade (commonly 1-2%). Stop-loss orders: Define how much you’re willing to lose before entering. Risk-to-reward ratio (R:R): Aim for at least 1:2 (risk $100 to make $200). Capital preservation: ...

Price action in trading refers to the movement of a security's price over time, and it's the foundation for many trading strategies—especially among technical traders. Instead of relying heavily on indicators or economic data, price action traders study raw price movements, typically through charts, to make trading decisions.

Support and Resistance Horizontal levels where price has historically reversed or paused. Price action often reacts to these levels. Trends and Trendlines Identifying upward (bullish), downward (bearish), or sideways trends helps determine market direction. Breakouts and Fakeouts Watching how price behaves around key...

What is Binary Trading?

Binary trading.   Binary trading refers to a type of financial trading where the payoff is either a fixed amount or nothing at all. It's often described as an "all-or-nothing" option. Here's a breakdown: eg: Quotex.com 1. How It Works You choose whether the price of an asset (like a stock, commodity, or currency) will go up or down by a certain time. If your prediction is correct at the expiry time, you get a fixed return (e.g., 70–90% of your investment). If you're wrong, you lose the entire investment . 2. Key Features Simple Yes/No choice : Will the asset be above or below a certain price at a specific time? Short-term focus : Trades can last from 30 seconds to a few days. Fixed risk and reward : You know exactly how much you could win or lose before entering the trade. 3. Example You bet $100 that the price of gold will be above $2,000 in 1 hour. If it is, you get back $180 ($100 original + $80 profit). If it isn’t, you los...
