I merged my feeds from the delegates pricefeed script with the bot and made some slight further modifications
(USE WITH CAUTION - COMES WITH _A_B_S_O_L_U_T_L_Y_ NO WARRANTY what so ever)
+ fetches from BTER, BTC38, poloniex, bittrex
+ fetched prices for the other assets from yahoo (except WTI)
+ fetched volumes where possible (the crypto exchanges)
+ bots can now build averages, weighted averaged, median, or any other method based on the data available from all exchanges
+ Object: exchanges .. contains all results from polling and can be used in the bot
+ (almost) no modifications to the market maker bot (except that it has to build an 'average' of some kind from all available prices, and some variable renaming)
+ this bot should (in theory) be able to be market maker for GLD,CNY, and all other assets ... (do not use with 'real' money, unless you checked and rechecked everything)
Have fun ..
Disclaimer: I am currently _not_ yet running it!
Disclaimer 2: I am _not_ a python coder! Expect the worst!
//EDIT: I just merged Nathan's changes into the bot .. now multiple orders/cancels can be executes simultaneously .. at least within one bot ..
