you see everything that happened with ticks. intervals show a consolidated view. What happens if over a second the range was 10 cents and there were 1000 transactions but 99% of transactions happened at a specific price; intervals dont show that. take it to extremes. what do ticks show that a one year interval chart doesnt?
With 1 sec data you can't use footprint chart if you consider use this type of chart. You can't analyze accurately the bid vs ask volume and it will be less accurate to spot price absorption ( ask hit the bid and price don't go down or bit hit the ask and price don't go up ). Again, only if all of this really matters to you.
All types of charts show higher highs, higher lows / lower lows, lower highs. All types of charts are used by traders here. They'll all swear by which one is best (the one they use). Zoom out mute. Spend time focusing on the bigger picture As far as actual differences, tic chart will move fast when things pick up. Time chart always moves at the same speed
You can't or will likely have to have special software to chart the tick of more than one instrument (on a single chart). You can't chart the tick of an index because it does not trade (some api/software can workaround this). 1sec charts can be awesome for some things. Many software will not even show 1sec charts. I had to build my own fucking software because I wanted 1sec charts of the differential of the futures mid price and it's respective index. My other broker could do it, but with some glitches/limitations. I found tick to be useful only as a 'second opinion' on any read I had. I don't even really respect the tick data, because I know that the pros all have on-the-millisecond post and cancel so any tick data you see is necessarily abbreviated. Also, the NYSE calculates an aggregated tick for me via the dow internal.
