Opciones binarias bandas bollinger
At all times there is full transparency, so a trader can exit with the profit or loss they see on their screen in each moment. They can also enter at any time as the rate fluctuates, thus being able to make trades based on varying risk-to-reward scenarios. The maximum gain and loss is still known if the trader decides to hold until expiry. Since these options trade through an exchange, each trade requires a willing buyer and seller. Suppose the index is currently at 1,800, so by buying a call option you're wagering the price at expiry will be above 1,800.
