Hello support,

There is a way to use Line Break feed data in strategy like other feeds?

I want to use 2 Line Breakbars.
If I use:
@Configurable("Line Break:") public IFeedDescriptor fd = new LineBreakFeedDescriptor(Instrument.EURUSD, OfferSide.BID);
then it does not works and Ireceive error in java cosole during try to run stratgy

if I use:
@Configurable("Line Break:") public LineBreakFeedDescriptor fd2 = new LineBreakFeedDescriptor(Instrument.EURUSD, OfferSide.BID);
it works but in starting parameters I can select only Period (like 1 minute ...) but not (2 Lines) like in Tools->Preferences->Period (when I add LinePeriod feen on the platform)

Please explain to me how it works.

Regards,
Jan

Line break feed is available. The only problem is that it cannot be selected from @Configurable.

FeedDescriptor fd = new LineBreakFeedDescriptor(Instrument.EURUSD, OfferSide.ASK, Period.TEN_MINS, CreationPoint.OPEN);

Yes thanks,
I saw that, but please describe me how it works, I mean what does means parameters Period here and CreationPoint?
What means in relation to the available on the platform Line Break where I only can select "2 Lines", "3 Lines" etc...:

e.g. What is the equivalent of 3 Line Break in JForex API code?

Line break bars:
Let's take the lowest (L) and highest (H) value of last N bars (or "lines" in this context).
A new bar is created whenever a new tick breaks H or L value.

Image

If trend continues a new short bar is created.
If trend changes the direction new bar will be bigger because the price will have to cross all the previous bars.

  • First bar's end value is always equal to next bars start value.
  • Only last N bars are considered

The "line" means: price level that must be crossed to form a new bar.
