Can you be more specific what you consider huge? Did you buy quote boosters so that you can subscribe to more than 100 contracts?
From what you are doing, I'd say you'd only need to subscribe to monitor the Last Price and Last Size ticks. So you would look at roughly 4 - 5 call backs per contract per second.
You might want to review your approach and code. I am subscribing to a pretty massive amount of data (process and log them in a Json format) and my server does not break a sweat. And it's a very small server for today's standards. Just to give you some idea:
- The total volume is between 30million and 60million ticks per day and sometimes more than 1,000 callbacks per second for busy days
- That is all available market data for ~75 contracts
- Plus TickByTickLast and TickByTickBidAsk for five contracts (yes five. I ask for five and most of the days get five)
- Plus Level II for three contracts
We use the standard Java API..

Hi,
I am trying to monitor a list of tickers (lets say the list is big).
I want to know when one of the tickers reaches a certain price. The target price is generated by an algo so it's not just a %-change.
I tried subscribing to realtime data to all of the instruments but this generates HUGE amount of network traffic to the point that my code is not really able to process all of the events.
Is this possible to do with scanner subscriptions?
I dont find where I can specify that scanner subscriptions to work only with a specific ticker or a list of tickers.
