The notions of calls and puts are the very basic notions when dealing with options in general, and with binary options in special.
In principle, keeping a simple approach for everyone to understand, whenever you are buying a call option, you are expecting the price for the underlying security to go up and by the time the call option expires to be higher than the options strike price.
The same is very much true when dealing with binary options: when you are trading a call binary option you are looking for market price to go up, in order for that option to be a winner.
when a trader thinks the eur/usd price will close at or above 1.3100 level at 15:00 GMT, for example, he/she can buy a call option on that outcome;
let’s assume he/she buys at 14:00 GMT one call option with the price of 100 USD;
if price at 15:00 GMT is at or above the 1.3100 level, the call option’s profit = 75%*100 usd = 75 usd
The recordings that go with this chapter will show you live examples about what to expect from a call option.
