I've programmed a crypto currency trading bot. This article introduces the idea, some programming details and the documentation.
Trading assets can be a full-time job. If one doesn't want to spend the time, one can just buy in regular intervals for fixed amounts of money and realize the dollar cost average effect. Developing this idea a little further leads to buying when the prices drop to obtain more assets for the same money spent. In order to do it automatically, Chris and I have implemented a cryptocurrency buying bot: Vigilant Crypto Snatch.
The program started out really simple, as a single file Python script. It would use the Bitstamp API to query the current market price of Bitcoin. Then it would take the Cryptocompare API to query the market price a specified time earlier. If the prices had dropped a given percentage, it would send a buy order via the Bitstamp API. Time delay, drop percentage and amount of money to spend have to be set by hand, and in the first iteration by guess.
