I do not think there are bots trading Dash. I know I personally have been buying a lot of Dash this past week, and likely others have been doing the same. There is no historic trade data available to build a good bot trader.
If anyone figures out how to use the BTC38 api to poll recent Dash trade data, please PM me
I am getting a "503 service unavailable" error.

Hi everyone,

Please consider my proposal for funding DashTrader.info. More information can be found at: https://dashtalk.org/threads/proposal-dashtrader-info-lets-advertise-by-putting-dash-back-on-the-markets.8271/

I have also spread the word over here, though I'm not sure how much discussion it will generate:
