A High Option, which can also be called a Call Option, is an option which offers a return on investment of up to 85% in the event of an underlying asset expiring at a higher rate than the strike price.
Typically traded on a High/Low instrument, when trading binary options one places a High Option when speculating that an asset’s expiry rate will be higher than the strike rate.
For example, if you place a High Option on EUR/USD with a strike price of 1.3552 and the option expires at 1.3558, the trade is In The Money and you make profit.
If a trader places a similar option and the expiry level is at 1.3545, the trade is Out Of The Money and the funds are lost. Some binary options brokers may offer a small refund in case of a loss, though this is uncommon.
If the trader places a similar option and the strike price and current market price are identical, the trade is therefore At The Money, resulting in neither a win nor a loss.
High Options are more commonly traded by beginners because of their inherent simplicity and the higher ROI from winning trades.
