I'm thinking about using this only when the market is going down. It appears to lose BTC if market is going up in the short term. Also, maybe it's important to adjust the trading strategy based on the the market condition. Right now the market is very volatile, and I am wondering if the short-term strategy works the best in that case. If the market is flat and boring, there there is no point trading high frequency with a bot. I would be better off doing it manually, turtle-trader style.
Does anyone have experience in the variable efficacy of this product?
Granted it's your money (btc) I think most of us would advise you to stay away from this product. I tried for days trying to figure out what kind of trading strategy they were utilizing in it's decision making. It seems completely random, RSI, MAC, MACD, Stochastic oscillator, etc. I couldn't figure out what they were using. Like someone mentioned, it very well could be a man in the middle attack to steal bitcoins from traders. I honestly don't know, and without seeing the bots source code it's too difficult to tell.
They've admitted that they are using Ruby to code this bot, which is really a piss poor language to be using for algorithmic trading. Python, or hell even C++ and C# would be a better alternative than Ruby.
Best advice I can give, and this is from experience with a pretty good size loss is stay the hell away from this bot.
