Hi, I found a web site called surefirething.com, which has a Camarilla calculator. They want $99 to use their calculator. Do they have some secret formula? Is their calculator really any different?

Good question. Before buying it you should ask them for some more info about how they back tested it, what the probabilities are, what money management they suggest with it. That should give you something to compare it against the other pivots with. Also ask them what it trades best with, i.e. bonds, e-minis, other index futures, forex/currencies, stocks, commodities etc...
