A sty is a bump that forms on or in the eyelid as the result of a blocked gland. The word sty can also be spelled stye.. There are two distinct types of styes: hordeolum and chalazion. Each has different causes and treatments. A hordeolum is a blockage of one of the sweat glands found in the skin of the lid and base of the eyelashes, or one of the small sebaceous glands found at the base of the eyelashes. Sebaceous glands secrete sebum, a waxy, oily material.

Alternatively, currency trading options can be held alongside the underlying forex pair to lock in profits or minimize risk. In this case, limiting the upside potential is usually necessary for capping the downside as well.
