Hippo

A cryptocurrency exchange recording and playback package, based on the XChange library.

Reading Usage

To read data, you will need a database with data in it. A read only one is provided for you. You'll need to set your environment variables upon launch to the following values:

HIPPO_DB_URL=mongo.nefariousplan.com
HIPPO_DB_NAME=cryptomarkets
HIPPO_DB_USERNAME=hippo
HIPPO_DB_PASSWORD=hippo

Then, make a new MongoTickerDatabase, and get the feed for the currency pair, and turn that into a OHLCV data set:

TickerDatabase ticker = new MongoTickerDatabase("Bittrex");
Set<Trade> rawPriceData = ticker.get(new CurrencyPair("BTC", "USDT"));
OHLCVDataSet data = new OHLCVDataSet(rawPriceData, Duration.standardHours(1));

You can them stream that into any data analysis:

WeightedMovingAverageFunction wma = new WeightedMovingAverageFunction(10);
  data.stream().map(x -> new WeightedSample(x.volume, BigDecimal.ONE)).forEach(x -> {
  wma.addSample(x);
});

Writing Usage

To write data, you will need to provide your own database and credentials in the environment variables.

Then construct your XChange exchange adapter:

Exchange cryptopiaExchange = new CryptopiaExchange();
cryptopiaExchange.applySpecification(cryptopiaExchange.getDefaultExchangeSpecification());
exchanges.add(cryptopiaExchange);

And give it to a LiveTickerWriter:

new LiveTickerWriter(exchange);

And watch the data stream in!
