Hello API Support,

I would like to kindly ask whether is possible to publish here example of "Draw on all charts" "on Tick" method.
I mean for instance the mentioned horizontal line(s) (ask,bid) would move based on tick (real time).

Thank you for any response.

J.

Hi Jiri:

See the example in annex...



Trade well

Perfect JL,

Thank you.

bidLine = chart.draw("Bid", IChart.Type.HLINE, 0, 0);

Please don't use the deprecated methods, instead use:

IChartObject bidLine = chart.getChartObjectFactory().createHorizontalLine("Bid", tick.getBid());
chart.add(bidLine);

See more here https://www.dukascopy.com/wiki/#Create_and_manage_chart_objects

            instruments = Instrument.values();
            subscribed = new int[instruments.length];

You don't need to take care of the instruments, simply iterate the following way:

public void onTick(Instrument instrument, ITick tick) throws JFException {
        for(IChart chart : context.getCharts()){

and on stop do the following (if there won't be such object the remove will take no effect):

    public void onStop() throws JFException {
        // garbage collect
        for(IChart chart : context.getCharts()){
            chart.remove("Ask");

Hello API Support,

is there any reason why my last question has been deleted?


Regards,
J.

The bug will get fixed with the next JForex-API version.

I see, perfect.

Thank you.

Hello Api Support,

could you please advise how to get approximate solution (with help of deprecated methods) before the mentioned bug will get resolved?
For strategy "Add custom information in OHLC Index" (again based onTick method) I would need to use it at all opened charts (even same instruments)

Thank you in advance

J.

You should ensure the key uniqueness among all charts for each chart object you create.
Simply iterate through IContext.getCharts() and apply the logic likewise as it is given in the example.

Thank you,

It helped.
