Your javelin must land tip first. A throw landing flat or tail first is a foul and is not measured. The javelin must also land within the two sectors in the field set at an angle of 28.95 degrees to the runway. When the javelin lands outside the sector, your throw is foul.
The selected point is marked by the spike and the zero end of the tape is held at the spike. The tape is drawn tight through the centre of the circle. The distance is measured at the point where the tape crosses the inner edge of the circle directly back through the centre of the circle (there should be a mark)
Dropping of the discus outside of the circle during initial swings before the turn and throw results in a foul attempt. An attempt is considered a foul if the athlete touches the top or outside of the rim during the throw. If the discus lands on or outside of the sector lines the throw is determined to be foul.
In men's competition, the shot weighs 7.26 kilograms (16 pounds). The women's shot weighs 4 kg (8.8 pounds). American high schools usually use 12 pound (5.44 kg) shots for boys and 4 kg shots for girls; these are sometimes used as practice shots as well. The weight of the ball differs depending the age group.

A short put is a type of strategy regarding the selling of a put option. The option itself is a security in its own right, as it can be purchased and sold.
A short straddle is a combination of writing uncovered calls (bearish) and writing uncovered puts (bullish), both with the same strike price and expiration. Together, they produce a position that predicts a narrow trading range for the underlying stock.
A short call means the sale of a call option, which is a contract that gives the holder the right, but not the obligation, to buy a stock, bond, currency or commodity at a given price.
Covered calls are an options strategy where an investor holds a long position in an asset and writes (sells) call options on that same asset to generate an income stream. A covered call is also known as a "buy-write".
The second way to sell a call is to select “STRATEGIES” on the top left of the trade page, click “OPTION”, and finally click “GO” next to “Short Call Option.” To adjust the strike price, drag the pentagon from left to right. To adjust the expiration, click the “- TIME” and “+ TIME” buttons.
There are actually three things that can happen. You can buy or sell to “close” the position prior to expiration. The options expire out-of-the-money and worthless, so you do nothing. The options expire in-the-money, usually resulting in a trade of the underlying stock if the option is exercised.
For the writer (seller) of a call option, it represents an obligation to sell the underlying security at the strike price if the option is exercised. The call option writer is paid a premium for taking on the risk associated with the obligation. For stock options, each contract covers 100 shares.
Call Options Expiring In The Money. When a call option expires in the money The seller of a call option that expires in the money is required to sell 100 shares of the stock at the option's strike price. Short options that are at least $.01 ITM at expiration are automatically exercised by most brokerage firms.
Sell To Close (STC) means "Closing a position by Selling". Sell To Close is used for selling a long position. When you Sell To Close (STC) an options contract, you are actually selling the options contracts that you own to a market maker in order to realize a profit or loss.
Put Options Strike Price. A put option is just the opposite of a call option. With a put option, the buyer has the right to sell 100 shares of stock at the strike price before expiration. If the buyer chooses to exercise, the seller must buy stock at the agreed upon strike price.
