Q&As: tick chartsI can assume many people heard about other people using tick charts & tick-aggregated (xd) tick charts. You know, like 233 ticks, 512 ticks etc
1) It never makes sense to aggregate tick charts by ticks. You loose information. Unless there's a specific reason you're very well aware off, there's no sense in all these 64 tick, 89 tick charts or whatever many ticks;
2) General rule is when you really need to use tick charts is when, well, there's nothing to aggregate... You're scrolling through resolutions lower->higher: 20Y bars (ok, maybe in the next century but still), 5Y bars, 1Y bars, 1Q bars, 1M bars, 1W bars, 1D bars, 2H Bars, 30m bars... Suddenly on 30m bars, you realize that lotta stuff missing, you see the holes in the chart, no trades happening during these particular intervals ie no bars were formed. And at this point, generally when you have more than 30% NA values, now it's the time to substitute the current resolution with pure tick chart, not before, not after. So now, instead of 30m bars you use tick charts, and obviously you stop scrolling deeper into resolutions.
3) the last 256 ticks (general rule, can be expanded and expanded and expanded) is what you're interested in;
4) Regardless the vehicle, real volumes (not the inferred ones) are used on ticks charts.
