GetCurrentAsk() Efficiency

[ScottB]

Does anyone know the relative efficiency of GetCurrentAsk/GetCurrentBid vs. storing the bid/ask in OnMarketData?

The real issue is where is the data stored - my machine or on a remote server. I am trying to avoid calls to remote servers whenever possible to reduce latency.

Thanks

Hello Scottb,

Thank you for your post.

Calls using GetCurrentAsk() or GetCurrentBid() will retrieve locally from your machine, not a remote server.

Thanks for your quick response.

From other posts it appears if I check GetCurrentBid/Ask in OnBarUpdate vs storing the data from OnMarketData myself, I will avoid race conditions between the internal NinjaTrader data structures which are updated prior to OnBarUpdate events and the bid/ask prices available in OnMarketData - is that correct?

Thanks
Scott

Hi Scott, that's correct - for the bid, ask, last the OnBarUpdate() related methods would be best if you're not dependent on their exact event timing (as you would have access to with OMD).

Perfect! I only wish trading were so precise that I would need exact timing but unfortunately, I think my best algorithms are just one step short of guessing and I have been doing this a very long time.

As always, thanks.
