Latest API in live:

According to javadoc history.getLastTick only throws an Exception if the instrument being requested is not active. Is active something different than subscribed?

main.java
....
//subscribe to the instruments
Set<Instrument> instruments = new HashSet<Instrument>();
instruments.add(Instrument.EURUSD);
LOGGER.info("Subscribing instruments...");
client.setSubscribedInstruments(instruments);
....


strategy.java onStart():

for (Instrument in : context.getSubscribedInstruments()) {
console.getOut().println("subscribed to: "+in.toString());
}

log output:
"subscribed to: EUR/USD"


Code in question (called at end of onStart in Strategy):

long last_tick=history.getLastTick(Instrument.EURUSD).getTime();

2012-02-01 17:10:38.902 ERROR DCClientImpl$DefaultStrategyExceptionHandler - Exception thrown while running onStart method: null
java.lang.NullPointerException

Desktop live platform the same code works.

Could it be that lasttick / general history based methods can only be called after the platform has received its first tick(s)?

e.g. those methods cannot be called in the standalone api in onStart() since there have been no ticks / history connection created?

This would also explain why this code works on the desktop platform since the platform / feed itself has already been running before the strategy and received ticks.

The code works in onBar() in standalone too. It should be updated in documentation (i couldn't find any reference to this case) that some history methods only work once first ticks/bars/whatever have been received in standalone.

Workaround:

Put your history stuff at the end of onStart and call sleep before it:

Thread.sleep(30000);

Alternatively you could probably loop getLastTick with try/catch until it doesnt throw an exception.

According to context.getSubscribedInstruments() the Instrument is already subscribed. I still have to sleep for some time before i can call the mentioned methods.
