[Simplified API] PositionListener Issue in v7.1.0 build:7

[Gregory]

Bookmap version 7.1.0 build:7

After thorough testing, I have concluded that the PositionListener isn't being called. This can be confirmed by running OrdersDemoNoHistory.java in the DemoStrategies repo here:

Code: Select all

https://raw.githubusercontent.com/BookmapAPI/DemoStrategies/8980c39106f57926559b6ac74e27b1f1b25312b9/Strategies/src/main/java/velox/api/layer1/simplified/demo/OrdersDemoNoHistory.java

https://github.com/BookmapAPI/DemoStrategies

Orders are executed, however onPositionUpdate never seems to be called. How else can we poll the system for positions? Is there a similar method to poll for orders, aside from verifying them as them populate onOrderUpdated?

Thanks,
Greg

Hi Gregory,
was that live or replay mode? We've been solving the issue with position listener in the replay mode but the live mode must be working.

We're talking about replay mode. Is there another way during replay to poll the system for positions? Also is there a similar method to poll for orders, aside from verifying them as them populate onOrderUpdated?

Yes, there is, but not within the Simplified API.
Please take a look at "AveragePrice" from DemoStrategies, class Layer1ApiAveragePositionPriceDemo.
There is an object dataStructureInterface you can get a list of TreeResponseInterval-s from.
The 0-th element of the list will be a collection of aggregated events which happened no later than t0 moment;
enery n-th element (assumed n > 0) will be an aggregation of events from (t0 + n * intervalWidth) moment to (t0 + (n - 1) * intervalWidth) moment.
Take a look at CaclulateValuesInRange method as an example of getting a list of orders.
As soon as you get a list of orders, you're able to calculate your position based on orders' status.

Hi AndreyR,
it seems that the issue about the PositionListener is still here!

Have you news about it?

thank you...

Hi. We don't currently provide position info or balance in replay and client-side simulated trading mode. We are planning to improve the simulator at some point, but currently it's not done.

I am not in replay mode but in real time mode....however the trading mode is simulated...

So, is it working only in real time and real account trading, right?

thank you for your response

[Andry API support]

Right. It will be fixed but the date has not been set yet.

Is there a way to know (using the API) if you are on Live or Sim/Replay? That way we can workaround this issue using an internal "Position Listener" based on what is executed after the code/addon is loaded.

[Andry API support]

hi blk! No way to detect sim mode at the moment. You can figure out Live or Replay by comparing current and provider timestamps.
1) get provier time:
- (for Simplified Api) implement TimeListener, override onTimestamp method

Code: Select all

    @Override
    public void onTimestamp(long t) {

- (for non-simplified) get time from provider

Code: Select all

long t = provider.getCurrentTime();

2) subtract provider time from current nano time

Code: Select all

long a = NanoClock.currentTimeNanos();
Log.info("" + (a - t));

For Live data the result will typically be around 1 * 10^6 (nanos) but it depends. For Replay it will be significantly greater.
