Numerical their output, just a different code, I want to know, they still have what distinction?

public void onAccount(IAccount account) throws JFException {
        MyLastEquity1 = history.getEquity();
        MyLastEquity2 = account.getEquity();
        console.getOut().println("1 is"+MyLastEquity1);
        console.getOut().println("2 is"+MyLastEquity2);
    }

See:

https://www.dukascopy.com/client/javadoc/com/dukascopy/api/IAccount.html#getEquity()

I see..
but why it is updated about every 10 seconds,isn't 5 seconds.
this is my code .

public void onAccount(IAccount account) throws JFException {
        MyLastEquity2 = account.getEquity();
        
    }

public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
        console.getOut().println("2是"+MyLastEquity2);
    }

OK,I get it ! I know what I need!

onTick :Here one would implement a strategy logic which is related to price change.

onbar :Here one would implement a strategy logic which is related to time period.
