I'm using 20/42@15m at Bitstamp lately and it has performed very well during those post-rally conditions. I sometimes buy back some BTC gradually during hard crashes (having an option in the bot to do that would be awesome), so I almost doubled my BTC over the last two weeks or so.
It sold at 644 today btw.
Youve kept the bot on 24/7? and double your coins at 15min interval?
No, when buying back manually you have to disable the bot or it will sell all your coins on the next tick.
