Stand alone project versus AlgoTrader enhancement

[jplusk]

This post relates to knowm/XChange#576

Douggie and Tim it seems like I came upon the same idea as the both of you (link1 link2), which is integrating the Xchange feed and order handlers with an existing trading software package, such as Algo Trader. I noticed that both of you had given this software project a try and I wonder why you decided to start this project from scratch versus building upon Algo Trader?

I did not, tim did all the main work. Parts are similar. Tim has done a
gteat job of a base frame work for crypto.

Not sure of tim's thoughts, but the key things seem to be:

Support for multiple cryptos on differnt exchanges

Running portfolios with multiple owners

Ability to easy arbitage multiple exchanges

Long precision support

I did start to modify AlgoTrader and spent a month or more exploring that
option. One big problem is that cryptos trade in fractional volumes, but
AlgoTrader uses an int for all volumes. I'm also not a fan of model-driven
development and couldn't really get the dev environment to play nice with
my setup. I think there were a couple other gotcha's I can't remember at
the moment. Anyway, Coin Trader IMHO is further along than the open-source
version of AlgoTrader, is built ground-up for cryptos, and keeps the good
ideas from AlgoTrader of loading modules into Esper.

OH also, AlgoTrader did not design for cross-exchange arbitrage. Their model doesn't distinguish between USD from one source and USD from a different source. Since the real FX market is highly efficient, it's a reasonable assumption, but in the cryptocurrency world, a fatal flaw. Coin Trader was specifically designed to handle price differences between exchanges.

Thanks for the responses and I look forward to following the progress of CoinTrader.
