Hi Dave
Yes, I use Trades Per Tick on Sierra Charts. They have three advantages over time based charts. They show beautiful higher highs and higher lows so the flow of the market is easier to see. The second advantage is being able to see the speed of the market.
They do lack decent wick formation which is my down side as pinbars are not shown clearly.
However the biggest reason I use Sierra charts for some of my 1 minute trading is MT4 misses some data from your provider so doesn't show every tick on your charts. On M1, it makes the flow of the market with higher highs and higher lows harder to see. Its like trading fuzzy bars.
Does that make trading volume bars ( Ticks per Bar ) better ?. My answer is yes if your trading 1 minute bars ( 133 Ticks per Bar ) and
5 minute bars ( 500 Ticks per Bar ) - No for higher
Do I use Ticks per Bar all the time - No
I prefer to trade on MT4 using time based bars with good trade manager instead of Sierra Charts.
On Index's, Sierra Charts just kills MT4.
Here's an example of a trade a month or two ago with 133 Ticks trading AUDUSD - notice the flow.
