One way I have been working the VTC volume is using  multiple bots. Fixed amount trade, earnings on percentage trade indicator, and cancel order ( like it does anything on f-ing Cryptsy ). I set each bot a bit different. ex 0.5/0.5 % change, 1.0/0.5 % change, and 0.5/1.0 % change. This way the bots tried different things and buy/sell at different points. Then you can set a manual drop sell point in case it falls through the floor. Or dynamic if you want, w/e.
