Dear All,
I coded a small tool to close all positions when a global trailing stop is reached. The tool plot on chart some infos like the higest/lowest profit, the current profit, etc ...
However I noticed that the infos are updated on chart only if I move the mouse on chart. As long as I am not active on chart, the infos are not updated. At least the current account P/L should continuously updating.
Attached is the code. Could someone look at it and tell me if something is wrong, missing or even if something isn't necessary in order to work correctly ?
Thank you very much.
Eric

I thin a chart.repaint(); will do trick, but you have to test... public void onTick(Instrument instrument, ITick tick) throws JFException {
for (int i = 0; i < charts.size(); i++) {
if (charts.get(i).getInstrument().equals( instrument)) {
IOhlcChartObject ohlc = ohlcArray.get(i);
prepareInfo(ohlc, instrument);
charts.get(i).repaint(); // <- add this!
}
}
}

Thank you for your help. Will test this asap.

Now, after reviewing my comment I must say that it is a stupid idea to call chart repaint in onTick(). As onTick() is going to repaint the chart of the tick's instrument, isn't it? Also, you might try Widget class for you purpose. It is almost the same as the OhlcInformer, but more user friendly (no need to hide the predefined values, for example). Anyway, we will see...

What am I supposed to do with this ? Implement this in my code or implemente my code in the widget code ? I am very new to java coding !!!

If you are new to java then we find it more feasible for you to use our example as the starting point and move your logic piece by piece to it. Essentially in the case of a chart widget you work with a JPanel which is a standard Java Swing component. In case it does not suffice with this and wiki example, see the Java Swing Tutorial. And if you don't use an IDE for writing your strategy, we would strongly advise you to use one, since not only there it is much more convenient to write your strategy but also you will be able to see the Swing component javadocs.

Only replace IOhlcChartObject instances in your strategy with the mentioned ICustomWidgetChartObject class, and use that one (the Widget objects) to show your messages on the chart, instead of an OhlCInformer.
There are some extra steps necessary (not just a simple replace), as clearUserMessages() for instance is a function of the IOhlcChartObject class only, but I think you can figure it out...
