This is not a bot but can you help find profitable pairs. This minimalize time to find it you must only check how much coin is avaible to trade for lower price, how much is to sell on higher price and if this coin isn't disabled on this exchanges. In the same time you can check much pairs earlier i play on my old arbitrage script and take some profits from it maybe  not 100% but somebody have luck to double it my average daily profit earlier: about ~5 up to~10%
