<<It used to be real easy to scalp, infact it took me about 1 month to change 1200 into 3500>>
I turned $300 into $4000 in one day, recently. Just posting this to let others know that it can be done.
One trade, for example: 50 contracts at $20 ($1000), closed that day above the binary ceiling, payout $5000.
The problem is that the next day I gave back $2000 - if you wait too close to expiration, and you aren't close to the underlying price you get stuck with a worthless contract. This can happen VERY easily, and VERY fast.
Overall, HS is a different animal, and you can't really compare it to active futures trading. After all, you aren't trading futures, you are betting on their outcomes, in a binary fashion. You can do this with $100, so it's great for people who want to play around.
If you haven't tried it, it's worth checking it out, as you have very little too lose (assuming, of course, you only put down a little bit of money).
