You should ask the Energizer how much, he's free to set his own prices. Guessing it would not run on your Mac unless your running windoze emulator.

For me, it was plenty expensive, but I think I made the right choice. Bought it on high lucky profits, and not having a heart-attack anymore on huge market swings, just incremental profits instead...

And just to be clear, I'm not a shill for Energizer. I started by specifically searching for bot-traders on Google and ran across his announce here, from way back in March.

This part of his announcement below made it worth the money for me. I mean he's way ahead of my curve, maybe he's onto something...

"EnerBot is a modular/custom Mt.Gox trading bot. I've started developing EnerBot 18 months ago. During this period EnerBot used hundreds of different trading strategies until it matured and reached its final flexible/profitable trading algorithm, that I've been using privately for the last 6 months."

So far it's working for me. I took a week or so before I actually took the plunge to purchase. These things you never can tell, mostly just looked back on posts here long-time back from Energizer to feel comfortable he's not a scammer. I felt that most scammers don't take a year or so making posts that portray themselves as up-standing citizens, before they scam you...

I was right, Energizer is indeed an upstanding citizen and has a good product and good support after the sale. If you can afford it, I recommend it...
