Chart Time Update Interval

Versus:
-frequency of trades in specific instrument
-personal comfortibale reactionspeed
-entry strat, (trail) stop strat
-available cpu

Thinking about it, I can live comfortly with 2 Chart updates every second.

How many:
-chart udates do you have in your timeframe?
-do you need?

So I want to update my chart every 500 millisecond = 0.5 second.

I wrote my own charting software. There is no provision for setting update frequency because charts are updated every tick. Even in fast markets, on four screens, modest graphics cards (NVS285), a quad core Q9550 is still 70% or more idle. Data feed is IB for futures and DTN IQ for stocks. Code is all Java.

Technically the trick is to repaint last bar only per tick and only update whole chart on the open of a new bar.

With modern CPUs and graphics hardware, there is no excuse for two updates per second etc etc. Vendors should fix their software. If they can't or won't, find another vendor.

Price ladder doms are likely to be more CPU intensive than charts.
