Sorry, still not sure I follow. Think of the alias as of a key that identifies an instrument. There is no guaranteed relation between that key and the instrument itself - that's just an identifier. So, you get identifier for the next callback inside onCurrentInstrument, then store it and you get act...

Hi. I'm not 100% sure what you are trying to achieve. Are you trying to understand which alias the MultiInstrumentListener# onInstrumentAdded belongs to? If so - you get onCurrentInstrument right before that call (same as with other types of updates - you will get onCurrentInstrument first, and actu...

Hi, There is, presumably, a microcode bug, affecting running Java on 10th and 9th gen Intel CPUs, so you might want to avoid those: https://bugs.openjdk.java.net/browse/JDK-8263710 (so maybe don't get 10850k; for those affected - switching to SerialGC in bookmap settings might help, also see below) ...

Hi. Is your intention to listen for that data or to send this data into bookmap? Please note, that when selecting the 1st or 2nd mode on the launchpad (trading simulated by bookmap) you will not receive those events in your indicators since simulated trading layer just does not currently support tha...

Hi. If you are writing a Layer0 adapter (connector) you can send updates via onStatus and onBalance callbacks.

Hi. Let me add to the answer... While you can't use that functionality directly, you can replace it by simply sending multiple orders for the same price with different bracket parameters. For the most part that will result in nearly the same result (main difference is that you can't atomically modif...

Unfortunately there is no way to do it with single action, but you can do it as below: To cancel all you need to issue a cancellation requests on all orders. Ideally you should group those into a batch using OrderCancelParameters#batchId and OrderCancelParameters#batchEnd. To actually flatten you sh...

Ok, so I guess we are down to two options, both would be feature requests:
- letting adapter send historical data to bookmap
- letting adapter define non-bookmap historical servers (i.e. you provide you URL to a server that returns data in some format defined by us)

Any comments on those options?

Hi. Unfortunately we don't support that directly via API at this point. We can, however, consider some alternative ways to achieve that and/or handle it as a feature request to add such API capability.

Which source are we talking about? (license restrictions differ, and so do the options).

Hi. Let me clarify: is your intention to insert historical data that you retrieve from your own source into bookmap?
