I'm getting long delays on my quotes with Quotetracker recently with heavy trading. My Ensign Windows app is not affected by this and is working well with IQFeed. The Quotetracker app has been getting worse recently. My Internet connection is fine because all of my other apps are working well.

Just an update for other QT-IQFeed users, I was able to reduce this lag by removing a number of chart windows and symbols off my watchlists. Before, I had like 12 windows spread across multiple monitors and about 250 symbols on my watchlist. Now I have only 4 to 6 windows up on one monitor and about 100 symbols on my watchlist. I also stripped some indicators off my charts.

It appears QuoteTracker just can't handle the load compared to other competitors that I use. It used to get bloated and slow down over time (i.e. - bottle neck). I recommend other users to keep it simple. It just can't handle this. I like QuoteTracker for its charts but it needs to be streamlined architecturally from the software development stage.
