Who Trades Options? Buyers, Writers, Hedgers and Market Makers
Every options trade has two sides. The buyer pays a premium for a right; the writer receives it and takes on an obligation. Around those two roles sit participants with very different goals: hedgers who want protection, speculators who want exposure to a price view, and market makers who quote prices on both sides and earn the spread. This guide from OptionLab (option-graph.com) explains who they are, what each one wants, and why knowing the other side helps you understand your own position.
Buyers and Writers: The Two Sides of Every Contract
An option is created when a buyer and a writer agree on a price. The buyer's risk is capped at the premium. The writer collects that premium and carries the obligation: to sell at the strike (a call) or to buy at the strike (a put) if the option is exercised. Because the writer's loss can be much larger than the premium, exchanges require writers to post collateral (margin). The Tel Aviv Stock Exchange, for example, publishes margin parameters for its TA-35 index options.
The same contract can serve opposite goals. A put bought by a portfolio manager for protection may be written by a trader who is willing to buy at a lower price. On option-graph.com you can switch a leg between Buy and Sell and see how the payoff flips between the two sides.
Hedgers: Paying for Protection
A hedger already has a risk and uses options to limit it. The classic case is an investor who owns shares and buys a put. The put costs a premium, which lowers the result when nothing bad happens, but it puts a floor under the loss. Whether that floor is worth its price is easy to test on option-graph.com before paying for it.
Suppose an investor owns 100 shares bought at $100 and buys one put with a $95 strike for $2.00 per share, or $200 for the contract. At expiration:
- Stock at $80: the shares lose $2,000, the put pays $1,300 after its premium, and the combined result is −$700 instead of −$2,000.
- Stock at $110: the shares gain $1,000, the put expires worthless, and the combined result is +$800.
- The floor: below $95 the combined loss stays at $700 -- the $500 drop to the strike plus the $200 premium.

- 100 shares bought at $100
- One put, $95 strike, $2.00 per share (100 shares per contract)
- No dividends, commissions or taxes
Hedging is not free and not complete: the premium is paid every time, and protection lasts only until expiration. Comparing the hedged and unhedged positions on option-graph.com shows the trade-off in dollars.
Speculators: Trading a Price View
A speculator has no position to protect. He uses options to express a view -- up, down, or a large move in either direction -- with a defined cost when buying. Speculators add trading activity, which can help others find a price. Their risk depends on the side they take: a speculative buyer can lose the premium, a speculative writer much more. Before acting on a view, model the exact position -- strike, premium and size -- on option-graph.com to see the breakeven the view has to beat.
Market Makers: Quoting Both Sides
A market maker continuously quotes a price to buy (the bid) and a price to sell (the ask). The gap between them, the bid-ask spread, is how the market maker is paid for providing liquidity and taking risk. Market makers usually hedge the positions they accumulate rather than betting on direction. Their quotes set the prices you actually trade at, which is why the calculators on option-graph.com ask you for the premium you expect to pay rather than a theoretical value. According to its product specification, the Tel Aviv Stock Exchange has market makers in TA-35 index options.
For everyone else, the spread is a cost: buying at the ask and selling at the bid loses the spread even if the price does not move. Including that cost when you test a trade on option-graph.com gives a more honest picture of the breakeven.
Why the Other Side Matters to You
Knowing who might be on the other side explains prices you see. Strong demand for protection can make puts expensive. Wide spreads signal thin trading. A writer's margin requirement explains why selling an option ties up capital even though it brings in a premium. None of this predicts direction; it explains costs and risks. Before trading, look at the full position -- both sides, the premium and the spread -- for example on option-graph.com.
Risks and Limitations
Hedges cost money and expire; speculation can lose the whole premium or more; writing options can lead to losses far beyond the premium received and to calls for more collateral. Market makers may widen spreads or quote less in volatile markets. Options are not suitable for every investor.

Summary
- Every contract has a buyer (a right, capped loss) and a writer (an obligation, collateral).
- Hedgers pay premium for protection; speculators trade a view; market makers quote both sides for the spread.
- The bid-ask spread and the writer's margin are real costs.
- Understanding the other side explains prices; it does not predict them.
- Test both sides of a position, buyer and writer, on option-graph.com before trading.
