Hello,

i need to get a non dominant side of DOM data.
Is it possible in ascil or not ?

Maybe with function like AskDOMSortPred ?

There is no information about that in entire internet or sierra site ..........

Thanks For Help
Dave

p.s.:i got a older version of sierra.
function like // sc.GetRecentAskVolumeAtPrice() + bid
// sc.GetCurrentTradedAskVolumeAtPrice + bid

not available !

If I understand your question correctly you are referring to the side that does not drag in resting volume to the starting position. So as an example.

The market is at Bid = 2000 / Ask = 2000.25. Then after a little bit of fighting, the price moves up by 1 tick.
So with the new price level we have Bid = 2000.25 / Ask = 2000.50. At this point, the Ask will be the strong side and drag in resting volume 1 level out to start the price level, but the Bid will be the weak side and start the price level with 0 volume. It will have to be spontaneously back-filled..... Or the level will just immediately break. It usually just immediately breaks by the way.

So if you could just call your level 1 volumes, then you can get both the strong side and weak side resting volumes.

There is no such thing as resting level 2 volumes for the weak side. That is why this is the weak side, because it can not use resting volumes. So the only way to ever see this is to call it from the level 1 feed, as soon as you hit level 2 (Beyond just the best bid / best ask) all you will see is strong side asks above and strong side bids below.

I can't give you the syntax for Sierra, but I hope this helps.

PS: I could give you everything you could possibly need with NT though...
