Options glossary
Key ideas before any simulated trade.
Call option
A call gives the buyer the right, not obligation, to buy an asset at the strike price.
Put option
A put gives the buyer the right, not obligation, to sell an asset at the strike price.
Strike price
The fixed price used to calculate whether an option has value at expiration.
Expiration
The date when the option contract ends. After expiration it may be worthless.
Premium
The price paid to buy the option. For buyers, this is the maximum loss.
Breakeven
The underlying price needed at expiration to recover the premium paid.
Risk
Options can move quickly and expire worthless, so exposure is capped in this simulation.
Leverage
A small premium controls 100 shares, which can magnify both gains and losses.
