Hi Dukascopy Community
I have question concerning the fastest access to tick data. I am going to do some scalping and I am wondering if my thinking is right:
Of course after prior subscription to the instrument While in onTick I am filtering data:

if (instrument == Instrument.EURGBP )

than I try to do some things and question appears:
Is there a possibility to write to variable current value of bid and ask side?

Or maybe there is faster way for example:

history.getLastTick(Instrument.EURUSD).getAsk()

My point is just to get the faster access for computations to the current values on the market.

Could you please advise me what is the best way to achieve this?

Regards

The fastest way is to fetch the tick from the onTick method as it gets called every time a new tick arrives.

public void onTick(Instrument instrument, ITick tick) throws JFException
{

}

You don`t have to ask for a tick, as it is already there (the tick parameter of the function is always the latest tick).

Thank you for answer.
What if the strategy includes playing on two pairs, for example eurusd and audjpy. In such situation strategy needs to know what is the last tick of each of those two.
For one of those you've already explained, but how to get the value of last tick of second currency pair?

To be clear please find described situation below:

public void onTick(Instrument instrument, ITick tick) throws JFException {
if (instrument == Instrument.EURUSD){
Some computation with last values of eurusd and audjpy; 
}
if (instrument == Instrument.AUDJPY){
Some computation with last values of eurusd and audjpy;
}
}

Regards

in that case use ITick.getLastTick.
