Re: Demo Execution Strategies

Hi mpxtreme, This is a kind of functionality that can be added via API by anyone, if it's needed. Source code of those 3 strategies is available here: https://github.com/BookmapAPI/DemoStrategies/tree/master/Strategies/src/main/java/velox/api/layer1/layers/tradinghelper Regarding if/when we are goin...

Re: Bookmap live entry

Hi gruppes, Sorry for miscommunication. Regarding your specific case - I see that you are using 7.1 according to the error report, so you might want to consider going one version back to 7.0 - those are both beta versions, but 7.0 is closer to becoming a production one (7.0 will most likely not be g...

Re: Accessing the Order-book at indicator initialisation

Hi, The only thing I'd like to correct in what you said is that after module is loaded you get current order book stats via onDepth calls anyway - regardless of if you have SnapshotEndListener - the only thing this listener does is telling you "hey, this is the end of a snapshot, everything past thi...

Re: Accessing the Order-book at indicator initialisation

Hi, While current simplified API doesn't provide a ready OrderBook inside initialize it allows you to implement SnapshotEndListener interface. The state of the order book at that point (assuming you apply all onDepth calls to it) will be exactly what you would get inside initialize if it would be th...

Re: Identifying seller/buyer side from IB's tick data

Hi! When trade is received from a data source that does not provide aggressor information (or other info that allows to determine it reliably) bookmap tries to determine the aggressor based on relative position of the trade (i.e. trade on best bid usually means that seller is aggressor). Quality of ...

Re: Few license exceptions (in log file only) during bookmap startup

Hi, Bookmap just has an instruction to load all possible modules, and license check is applied on the loading stage. As long as you don't have a license to use those modules these exceptions will be displayed. You can safely ignore those as long as it does not mention strategy you are supposed to ha...

Re: onDepth not fired for US stocks instrument using DXFEED

Hi, that's happening because strategies/indicators are blocked with DxFeed due to exchange restrictions. I think we are missing a proper warning message, ideally it should inform you that it's blocked - I assume currently it does not.

Re: Demo strategies: QuotesDelta Indicator

Hi, what is the feed you are using it on? I've noticed that you created another topic, about DxFeed - indicators are blocked with DxFeed due to restrictions imposed by exchanges, but there is a good chance blocking isn't always working cleanly.

Re: Bookmap for MacOS

Hi tocflow, If I'm not mistaken (which I might be because I didn't research it too deeply, so please let me know if I'm wrong or if you have some useful links), GAIN only provides .net based API, and while it's probably possible to run the API library on mac (depending on what the library itself rel...

Re: two indicators with same zero line

You can apply same scale to multiple indicators by adding those to same AxisGroup object (just create an object and add both indicators to it).
