Question about OnBarUpdate and timing

[rt-trader]

Hi,

Could someone please clarify what happens in the following situation?

The current Bid has only 20 lots at say 866.00 which are taken in a single order.

The next OnBarUpdate processes this.

As that happens will GetCurrentBid() return the just taken Bid of 866.00 or the new Bid of 865.75?

I realise that I could get the Bid data via OnMarketData however as OMD and OBU dont always match (there is an intermitent 1 tick lag) it is possible when doing Bid/Ask analysis to apply OMD data incorrectly within the OBU portion of the indicator.

Thanks

GetCurrentBid() gets the bid at that point in time. If a new bid formed you will get the new bid.

You can just run your bid/ask analysis from OnMarketData() or OnMarketDepth().

Josh,

Thanks for the rapid reply...

That is as I expected and yes i can use OMD however as mentioned in my first post this can return inconsistent results because of the lag issue.

I appears (unfortunately) there is no way around the issue of getting 100% accurate Bid/Ask analysis with Ninja at the moment....

Anything being done about this in version 7?

Thanks

rt-trader,

GetCurrentBid() just accesses the data directly. So it can actually be ahead of OnMarketData(). OnMarketData() is event driven so it is not necessarily the absolute latest bid price while GetCurrentBid() is the moment you call it. But remember, GetCurrentBid() from OnBarUpdate() is not updated on every single bid change since a bid change does not constitute a bar update event.

As bid prices change back and forth it may seem like a delay but there really isn't one. Hope that helps.

Thanks for the clarifications Josh...
