Automated Trading
To implement signals and automated strategies, you connect Esper event queries to Java code like this:
@When( "select avg(priceAsDouble) from Trade.win:time(30 sec)" )
void checkMovingAverage( double avg )
{
if( avg > trigger )
context.publish( new MyIndicator(5.31) );
}
@When( "select * from MyIndicator where myIndicatorValue > 5.0" )
void enterTrade( MyIndicator s )
{
orders.create( Listings.BTC_USD, 1.0 )
.withLimit( 650.25 )
.place();
}You then attach this class to a Context to receive Esper event rows as method invocations.
24Hr OHLC Bars
Strategy needs to implement a .getInterval() method to return a double in seconds of the size of the bar.
Default simple statful stretegy is 86400 (24Hr) cointrader-esper.cfg.xml
<plugin-view factory-class="org.cryptocoinpartners.esper.OHLCBarPlugInViewFactory" name="ohlcbar" namespace="custom"/>
epl
- Create an esper named window to add the OHLC bars into
create window OHLCShortWindow.win:length(10)
as
select *
from
Bar;
- Add the OHLC bars to it
insert into OHLCShortWindow
select *
from Trade.custom:ohlcbar(timestamp, priceCountAsDouble, market,TestStrategy.getInterval());
- Select values from OHLC bar window
select * from OHLCShortWindow as ohlc
TALIB Set Up
cointrader-esper.cfg.xml
<plugin-aggregation-function name="talib" function-class="org.cryptocoinpartners.esper.GenericTALibFunction"/>
epl
select coalesce(talib("atr", max, min, last, 9),0) as atr from OHLCShortWindow;
