They are different since binary options is not connected to Forex market and they are just depending on the movement of the market and they dont put any effect.
Obviously you are not talking out of experience and in a public forum as this, it helps if we do not pass on false information, because you can never tell who may want to use it someday.
What is fact is that, prediction of the direction of currencies is possible with binary options as it is with forex trade, they only differ in the conditions that needs to be fulfilled before profit is made. With binary options, a single tick might be all that is needed to end in the money and in case of a lose, only the amount that is wagered is lost.
I agree, both relies on the same price forecast of the stocks. Both are affected by outside factors, and both is predicted in the same manner like using charts, news, etc. The difference of this two is that, they have different pay out, fees, risk and entirely different liquidity structure and investment process.
