Realistically

will 300 on my account suffice do i need more buying power?

Who knows? No context.

Are you referring to Nadex? Are you trading binaries or spreads? What strategy or system are you using?

nadex spreads. using alchemy and sharpshooter.

$300 is way too small. Your just going to lose it. Get a decent size account b4 you start to trade. I don’t recommend trading with less than $2000. You could trade with less but your going to be an emotional trader which is not good.

i was thinking out having a go with the binary hunter.
