Currently I am using esignal and $tick updates only every 6 seconds. Are there any data providers that update this in realtime or is this an nyse update delay issue? Thanks.
would like to know this as well (my data feed updates every ~10 seconds). Especially on a day like today (with some insane swings), it would be nice to see it in a higher frequency.
If it is vital to your trading protocol you can build your own TICK Indicator and update it every second or half second... using Excel, a DDE feed and VBA Code...
With that flexibility.. It can match the general TICK or be your own hybrid TICK...
If you put tradestation tick versus esignal, you will see that tradestation is way faster. It's close enough to real-time to get pretty decent readings off it. You can put the $tick on a 1 min chart and recognize up trend days when it continuously bounces off the zero line. You can take profits when you get +1000 readings.
