(Read the post after this one first Agent, I realized you are talking about dailies and I am talking hourly)
Yes the payout does adjust as the price moves but what Nadex does is say at 10:00 A.M. ET they put out a price 1.3100. You either say by expiry it will be above or below and it will be approx. 50/50 if spot is at this price. Now at 10:15 it moves to 1.3120. With Nadex your stuck with above/below 1.3100 or above/below 1.3200. So lets say in this scenario you are sure that it will not break 1.3150, with Nadex all you could do is say below 1.3200 but the R/R would be bad since it is already below 1.3200. Probably risk 80 to make 20.
On the others the price is constantly moving, with spot. At 10:15 your options would be above/below 1.3120. If you are convinced of a move to 1.3150 and then fall, you can wait for 1.3150, place the trade below 1.3150 and then as long as it is below 1.3150 at expiry you win.
For me all I use is two moving averages and one or two probabilities. I trade when it gets to some moving average I believe it will reverse on and I place the trade at that price when it reaches it. Then all I need is it to reverse 1 pip at expiry and I'm in the money. It can move against me as far as it wants without stopping me out, as long as by expiry it comes back to at least one pip in my favor, I'm in the money. I countertrend for the most part but you could trend trade it too, if you think once it hits some price it will fly in that same direction just wait for your price and place the trade in the same direction it is moving, as long as at expiry you were right by 1 pip you're in the money.
Optionbit has a demo so you could see what I'm talking about or you can just go on their site and watch it and you'll see how it is different. The demo when I used it was good for one whole day! So if you're going to get it be ready to test it quickly. None of the others have demos that I am aware of.
