Hi oceanis,

to get Iceberg and Stop  value directly from module

currently not supported but you can leave your request in this topic.

how to use alert in a Strategy ? Have you Java sample ?

Take a look at this example. An alert is played on every n-th trade.

Code: Select all

package velox.api.layer1.simplified.demo;

import velox.api.layer1.annotations.Layer1ApiVersion;
import velox.api.layer1.annotations.Layer1ApiVersionValue;
import velox.api.layer1.annotations.Layer1SimpleAttachable;
import velox.api.layer1.annotations.Layer1StrategyName;
import velox.api.layer1.data.InstrumentInfo;
import velox.api.layer1.data.TradeInfo;
import velox.api.layer1.layers.utils.SoundSynthHelper;
import velox.api.layer1.messages.Layer1ApiSoundAlertCancelMessage;
import velox.api.layer1.messages.Layer1ApiSoundAlertCancelMessage.Layer1ApiSoundMessagesFilter;
import velox.api.layer1.messages.Layer1ApiSoundAlertMessage;
import velox.api.layer1.simplified.Api;
import velox.api.layer1.simplified.CustomModule;
import velox.api.layer1.simplified.InitialState;
import velox.api.layer1.simplified.TradeDataListener;

@Layer1SimpleAttachable
@Layer1StrategyName("Sound Alerts")
@Layer1ApiVersion(Layer1ApiVersionValue.VERSION2)
public class LastTradeSoundAlert implements CustomModule, TradeDataListener {
    private Api api;
    private int tradeCounter;
    private String alias;

    // an alert will be played for every n-th trade
    private int n = 10;
    private byte[] alertSound = SoundSynthHelper.synthesize("alert");
    private Layer1ApiSoundAlertMessage alertMessage = new Layer1ApiSoundAlertMessage(alertSound, "", 1, null,
            (a, s) -> {
            }, this.getClass(),
            alias);

    @Override
    public void initialize(String alias, InstrumentInfo info, Api api, InitialState initialState) {
        this.api = api;
        this.alias = alias;
    }

    @Override
    public void onTrade(double price, int size, TradeInfo tradeInfo) {
        tradeCounter++;

        // play alert for every n-th trade
        if (tradeCounter % n == 0) {
            api.sendUserMessage(alertMessage);
        }
    }

    @Override
    public void stop() {
        // cancel queued alerts for this module if there are any
        // so they will not be played when the module is stopped
        Layer1ApiSoundMessagesFilter soundMessagesFilter = new Layer1ApiSoundAlertCancelMessage.Layer1ApiSoundMessagesFilter() {
            @Override
            public boolean shouldCancelMessage(Layer1ApiSoundAlertMessage message) {
                if (alias.equals(message.metadata)) {
                    return true;
                }
                return false;
            }
        };
        api.sendUserMessage(new Layer1ApiSoundAlertCancelMessage(this.getClass(), soundMessagesFilter));
    }

}

Hello,

Thank you for this answer.

It will be more simple to Log all Alert in a file.

Is there a way to access the values from the SI indicator with an API?

Thanks

[Andry API support]

Hi,
SI-on-chart is able to broadcast its values via API, more info here
https://bookmap.com/knowledgebase/docs/ ... -api-brapi
Do you use Rithmic or BookmapData?

[jayenoh]

Thanks! I'm currently using BookmapData.  Are there any differences between the two?

[Andry API support]

BookmapData provides upto 48 hours of historical data, Rithmic has no historical data.
In the context of API:
1) BookmapData, by default, prevents user code running with realtime data. Please let me know if you need this feature.
2) Python API is unable to work with BookmapData realtime.
