Some data provides have limits on how many data feeds you can use at any one time. For example, Interactive Brokers only allows 3 Level 2 (Market Depth) feeds at a time.
Jigsaw does help with that by ensuring that feeds are shared internally.
In the above example, we have Depth & Sales, Summary Tape, Reconstructed Tape all using the level 1 feed from Rithmic for instrument ZBU16. The RapidTraderPro Broker Manager consolidates these requests and just makes one request for the Level 1 feed.
Subscription Monitor would show these subscriptions as follows:
If you hit a subscription limit you have 2 options.
1.Go to Subscription Monitor, find which tools have the subscription and then manually close them
2.Go to Subscription Monitor, select the subscriptions you want to close and click "Kill Subscription"
